"An Interview with NevilleThiele" - By Steve Mowry,Voice Coil 2006.

"…SM: What do you see asthe trends in loudspeaker design and development in the next tenyears?

NT: Active loudspeakers with equalization ,lower crossover frequencies, and more nearly omnidirectionalradiation. Theymay not be trends but seem to me a better way of doing things ….".

Introducing the Ultimate Equalizer

Exampleof The Ultimate Equalizer System Configuration Screen (BBM+CABS)

Majorcharacteristics of Ultimate Equalizer system are

Active system – allows amplifiers to exert maximum control over loudspeaker driver and makes crossover characteristics independent of driver loading.
DSP crossover and voicing – maintains crossover and voicing characteristics with mathematical precision.
Amplitude and phase HBT equalization – results in flat amplitude and phase responses and extends bass response.
Linear phase – maintains 0deg acoustical phase response of each driver, which results in transient-perfect system for correct spatial imaging ( realism, depth, resolution, ambience ) for multi-channel sound reproduction.
Minimum-phase/Linear-phase room EQ – removes most obnoxious room modes.
Available with BBM bass management and CABS active suppresor of room modes .
Remote control – via 2.4GHz wireless keyboard and mouse.
Built-in WAV Player - with this option, there is no need for any sound cards at all. UE will create and play 'playlists' with the standard CD-style WAVE files (16-bit/2-channels/44.1kHz) using motherboard codecs.
And also Hi-Res WAVE files 24bits/2-channels/96kHz and 24bits/5.1-channels/96kHz using motherboard codecs and digital add-on sound crads.
Use Windows Media Player, or install other Media Players – to create audio server and state-of-the-art loudspeaker management system ( user-friendliness, power, flexibility, cost efficiency and sound quality ) on one HTPC.
Removes 'flabby' or 'woolly' bass and provides linear-phase bass as commented by:
1. Michael Gerzon " The subjective effect of phase compensation of the bass from loudspeakers is very marked, giving a much tighter and more 'punchy' quality, with greater transparency, and interestingly a subjective extension of bass response of at least half an octave. The improvement is audible even on loudspeakers with a very high cut-off frequency, such as Quad electrostatic designs. . . . The benefits of bass phase equalisation are considered, by those who have heard itt , to be a substantial improvement over what was hitherto possible with analog technology, and digital equalisation provides a way of improving bass performance without going to ridiculously large giant space-consuming power-hungry monster speakers, and is certainly a much cheaper route ".

2. Keith Howard "As I pressed Play, I didn't know what to expect: a mild improvement or a revelation. To use a curry-house analogy, I was half-prepared for korma rather than phal. But when I compared the unprocessed and phase-corrected tracks, it took only a few seconds of the latter to persuade me that here was a significant improvement. Just as Michael Gerzon described, the phase-corrected sound was both weightier and punchier, and distinctly more coherent. It simply sounded more like a bass guitar, to the extent that I almost hummed along—not something that I would normally expect to do when listening to a bass-guitar accompaniment shorn of all else (sorry, John), and certainly not an urge I felt with the unprocessed track. Still, time-consuming as it was, this experiment involved only a single music excerpt and was conducted in mono, and so hardly offers a comprehensive insight into the full benefit of bass phase correction. But what I heard convinces me that this is an area in which the application of DSP can make a significant contribution to fidelity."

Ultimate Equalizer V10 has been released.....

For full description of the program features,please download PDF manuals below. This release is recommendedfor i7-960, 3.2GHz or better processors. Please note, thatour software is periodically reviewed and fixes are implementedas an ongoing process.

List of improvements in Ultimate Equalizer V10.0

1. The size of project data files is reduced to half of the V9 size. This is quite substantial change, and allows for faster loading of project files.

2.MLS system uses WASAPI 16bit/24bit drivers instead of the legacy WDM/MME drivers.

3. RoomEQ measurements use WASAPI 16bit/24bit drivers instead of the legacy WDM/MME drivers.

4. Added second version of the BBM system. The FL channel is independently filtered and summed with Left Subwoofer, and FR channel is independently filtered and summed with Right Subwoofer.

5. Current Bass resolution settings (buffer-size dependant) are displayed on MLS transfer function screen.

6. Bit depth on the input-side can be set to 16bit or 24bit. Many contemporary motherboards only allow for 16-Bit depth on recording side due to compatibility with CD recordings requirements.

7. MLS system uses the same impulse response files as SoundEasy V21. The UE10 and SoundEasy V21 programs are compatible for impulse response measurements.

8. WASAPI Debug Mode. Useful to debug sound card drivers implementation.

9. Automatically appends buffer size and sampling frequency to driver's filename. Also, appends sampling frequency to impulse response filename.

10. Compiled and tested on Windows 10/64bit.

The UE includess inverse-HBT equalization , time-inverse processing that eliminates phasedistortion, crossover filtering, and partitioned convolution .Equalization of the individual drivers' response to the userspecified acoustic target is performed automatically with theclick of a button. The outcome is a transient perfectspeaker system with flat amplitude and phase responsesthat faithfully reproduces any input signal relative to thedesign point, as demonstrated by the ability of thespeaker system to play undistorted square waves.Shelving and notch filters are included to voice the speaker toother than ruler flat response and the time-inverse processingand be switched on or off as desired. Recommended sound card isLynxAES16 and Delta1010LT (capable of WASAPI technology inExclusive Mode). This stand-alone, fully self-containing programincludes ALL functions, that you need to createyour 'DSP-on-PC' system. The UE-PC incorporates RoomEqualizer and large 5.1 Home Theatre option (8in/16out).The program includes self-starting option, so you can arrangeyour PC to start running UE on power-up, and thus have the wholeprogram up and running by pressing 'Power ON' button onyour PC case.

SoundEasy v27 has been released......

SoundEasy + EasyLab system is acomplete modelling and measurementsoftware package. ( for full description of the program features, pleasedownload the PDF manual below )

SoundEasy operatesin time and frequency domains and models the complete design andadvanced (Phase/SPL/Zin - constrained)optimisation process of multi-way loudspeaker system, includingWMTMW arrays. The program allows for a complete characterisationof all drivers, including complex transfer function for soundpressure (amplitude frequency response) and input impedance. Directdata import functions from PC-based measurement systemsare included. SoundEasy will even tell you if your imported phaseis correct and will help you to correct it (using Hilbert-BodeTransform, HBT, during the import). Enclosure design includes 13 types of enclosures,including H/U Dipoles and handlesmultiple driver configurations. Up to 4 identical drivers can beplaced on the front panel to analyse diffraction distortion andmutual radiation impedance. Large-signal analysis isprovided and includes: BL(x) and Cas(x) non-linearity, portcompression and thermal power compression effects. Our NEW, full-screen, scrollable,re-sizable CAD section of theprogram, handles all electronics of the passive/active systemsuch as: complete and detailed passive or active crossoverdesign, and time/frequency/impedance compensation circuits. TheCAD system allows you to include advanced DSP components, like LinearPhase Filters, Time Delay Elements, andour own Super-Components, Mega-Componentsand Modular Crossover concepts, none of which can beimplemented in standard, passive crossovers. 100 of popularfilter/crossover types are built-in. Finally, complete systemresponses are obtained by taking into account mutual 3D alignmentof the drivers on the front panel, including off-axis simulations, tiltingand rotating drivers . As theRay-Tracing Methods are really not suitable for low-frequency(below 300Hz) room modelling, we have implemented extensiveevaluation of room and car cabin acoustics using Image Method andthe powerful FiniteElement Method for complex room geometries - ideal for 4sub-woofer placement evaluation, including two dipole subwoofers. The FEM includes modelling ofabsorption at each node and allows you to include openedwindows, carpets, heavy drapes, (any size) etc. in youranalysis. The program is quite large. It contains over 80plotting screens/control boxes for modelling various designprocesses and a number of 'calculators' for performingspecific modelling functions. There are also numerous dialogueboxes for customizing plotting and display functions. The programincludes support for design and optimization of Transient Perfectcrossovers. Small-Thiele loudspeaker model has been expanded byusing FEM to model enclosureresonant modes . Non-Coherence Analysis is included and Minimum-Phase Extraction is based on iHBT and Curve-Fitting Algorithm. Peak Power Dissipation ratio displayed.

DSPFunctions

1. CAD-based Digital Equalizer has been implemented to enable perfect filtering withsimultaneous equalization of ANY irregularities of SPL responsecurve. This has been accomplished by modifying the targetedfilter transfer function by the inverse SPL response of thedriver, and at the same time cancelling the parasitic'tails'of the SPL using Hilbert-Bode Transform. OurEqualizer allows you to audition your favorite audio-CD via thesound card and also includes simulating propagation delays due todifferent spatial location of the acoustic centers of drivers.This feature is significantly more advanced than typical DigitalFilter - see SoundEasy Reference Manual, Chapter 9 for details.Filters and Equalizers up to 2x4-way can be constructed andevaluated with suitable, MME-compliant sound card.

2. Digital Room Equalizer (DRE) allows you to step out of the loudspeaker box anddo something constructive with your room acoustic. The DRE is aHBT-based, minimum-phase equalizer, designed to put 'finaltouches' on your room transfer function. It includesfull-screen SPL pixel editor for precise modifications to yourmeasured SPL curves and other processing tools. Please seeSoundEasy Reference Manual, Chapter 19 for details. Will run onmost 16-bit, full duplex, stereo sound cards.

3. System Phase Equalizer works with already built loudspeakers and allows you toremove all phase delays due to enclosure and crossover frequencyresponses. Loudspeaker equalized this way will reproduce squarewave reasonably well, depending on amplitude irregularity. Pleasesee SoundEasy Reference Manual, Chapter 19 for details. Will runon most 16-bit, full duplex, stereo sound cards.

4. Advanced System Phase Equalizer . In addition to (3), the Advanced System PhaseEqualizer also equalizes the amplitude response of theloudspeaker system. When operated with a loudspeaker system, youwill be able to flatten the amplitude AND phase of the completesystem. Loudspeaker equalized this way will reproduce square waveperfectly. Please see SoundEasy Reference Manual, Chapter 19 fordetails. Will run on most 16-bit, full duplex, stereo soundcards.

5. Bass Synthesizer. This is a sub-octave bass synthesizer generating firstsub-harmonic of the lowest bass note present in the musicmaterial played through the synthesizer. The resulting bassoutput is user adjustable and is perfect way to give yoursubwoofers something to do. You can also write your own WAVfiles, while the bass synthesizer is working, so you can modifyyour favourite music, giving it tonal balance of your choice.Please see SoundEasy Reference Manual, Chapter 19 for details.Will run on most 16-bit, full duplex, stereo sound cards.

6. Digital Filter (FIR implemented as Fast Linear Convolution, and alsoas Partitioned Convolution ) function has been provided forauditioning your crossover design via sound card. Ourimplementation includes simulating sound propagation delays dueto different spatial location of the acoustic centres of drivers.You can also write your own, and read WAVfiles. Please see SoundEasyReference Manual, Chapter 9 for details. Filters and Equalizersup to 2x4-way can be constructed and evaluated with suitable,MME-compliant sound card.

EasyLab - Advanced is an expanded section of the SoundEasy program,dedicated to frequency and time domain measurements of the driverand room acoustics. The system incorporates digital (MLSand pre-emphasized MLS) and analogue (ESS) measurement system thathas been implemented for measuring SPL and Zin. Both methodsinclude powerful post-processing functions, including amplitude/timezoom-in on Impulse Response, scroll ImpulseResponse and analog input buffer, HB Transformfor easy determination of acoustic center of thedriver. Dual Channel Oscilloscope with built-in6 signal generators: Sine Wave, Square Wave, Pink Noise,White Noise, Two-Tone and Tone-Burst.Next, Spectrum Analyser with various screencontrol option (including WarpedFFT ), THD display, and the sameset of signal generators. Cumulative Spectra Decay (CSD)Analyser now includes Tone-Burst Waterfallsas well.There is also a Small-signal(T/S) and Qb extraction screen using Delta Mass andDelta Compliance methods, RLC Measurement screen,Distortion Analyser, including estimation ofnon-linear coefficients of BL(x), K(x) and Le(x)using truncated Volterra series expansion method, and finally,advanced Non-linear Parameter Measurement screenand modeller based on driver's differential equations andnumerical differentiation. EasyLab employs extensively MLS-typeof test signals, Hilber-Bode Transforms and curve-fitting methodsin it's measurement system. 'Curve Arithmetic'function for Digital and Analogue measurement functions is alsoprovided. Your SPL field measurements can be saved as a raw-datafiles, so that you can perform all post-processing andpresentation functions later, at your convenience - see SoundEasyReference Manual, Chapter 16 & 17 for details. Tone bursttesting method is also implemented. The next addition to theEasyLab system is RT60 measurement capability.The system incorporates Schoeder Backward Integrationand two methods for noise reduction: Truncated andSubtracted. THD/IMD measurement system and Cepstral Deconvolution have been added recently, and finally, a Matching Filter Technique has been implemented, in this release. CepstralDeconvolution and Matching Filter Technique both allowreconstruction of measured, echo-contaminated, low-frequencyresponse of a loudspeaker system. Non-Coherence Distortion analysis, CSD Differential plots and Large Signal Impedance Measurements are the latest additions to EasyLab section.

BoxCad isa sophisticated software tool (separate program) focused onenclosure analysis using acoustic impedance models and electricalimpedance models - highly recommended for advanced designers. 10models are built-in for your convenience, but you can letyour imagination fly and invent an esotheric enclosure andanalyse it using BoxCad - unlike using other loudspeakermodeling programs, you are NOT restricted to built-in enclosuremodels. Again, frequency and timedomain analysis is available. The results of the analysis can becombined with active/passive circuits designed with built-inelectronic CAD system. And yes!, you can model PassiveRadiator Band-Pass enclosures of any type with BoxCad.If you are concerned with vent non-linearitiy during turbulentflow - perhaps PR system will satisfy your requirements. And howabout an Acoustic Cannon ?.

BassBox Pro™ is a state-of-the-art speaker enclosure design program. It is used around the world by professional and amateur speaker system designers to design worldclass speaker boxes. BassBox Pro is very versatile and can be used to design speakers for a wide variety of applications including home hi-fi, home theater, car, truck, van, pro sound reinforcement, recording studio monitors, stage monitors, PA, musical instruments, etc.

Easy to Learn and Use
BassBox Pro has many features that make it very easy to learn and use. For example, when the program is first run, a Welcome window (shown below) will appear to help you configure the program and introduce you to its on-screen manual.

The on-screen manual (shown below) is extensive and contains most of the same information as the beautiful 364 page printed manual. Both the on-screen and printed manuals are the best in the industry and include a 'Box Designer's Guide', 'Sample Designs' and 'BassBox Pro Reference'.

BassBox Pro also includes a 'balloon' help feature (shown below). When the mouse pointer hovers over a control or label, a small text box will appear to provide a definition or explanation of the object below.

Box Design is as easy as 1-2-3
There are many ways to begin a speaker design with BassBox Pro, including the use of its innovative Design Wizard. In general, speaker design involves the following steps:

Enter the driver parameters such as Fs, Vas and Qts. BassBox Pro's driver database contains parameters for thousands of drivers.
Calculate the box volume and tuning. This is very easy with the program's helpful 'Suggest' button. It will cause BassBox Pro to recommend a box that will produce a smooth bass response.
Evaluate the performance with the graphs. This can include the effects of the acoustical environment. For example, BassBox Pro can estimate the in-car response in the graphs to show how the speaker will sound to passengers inside a car.

Each box design can be saved and re-opened or re-used later. As many as ten different designs can be open at the same time. Box designs can also be duplicated so that driver or box information does not need to be re-entered.

Design Wizard
BassBox Pro includes a powerful Design Wizard (shown below) to help new users quickly design a speaker. It can start with either the driver or the box and then it will walk you through BassBox Pro as it prompts you for information in an orderly progression. In this way it serves as a 'smart' assistant to help you use the program.

Main Window
The centerpiece of BassBox Pro is its resizable main window (shown below) that includes a summary of all open designs. Up to ten designs can be open simultaneously.

A mini preview graph is provided for each design to show its amplitude response. These preview graphs are automatically updated whenever a design is altered, providing 'real time' feedback. A small picture beside each mini graph displays the box type that has been selected (closed, vented, bandpass or passive radiator). A summary of the driver and box parameters is listed in a text box.

Largest Driver Database
BassBox Pro includes the world's largest database of driver parameters! Users can add, edit or delete drivers and the database can be searched by manufacturer, driver model name, driver parameters or suitability for a closed or vented box.

Driver Properties
Information about a driver is contained in the Driver Properties window. The driver information can be entered manually, imported from another BassBox Pro or BassBox Lite speaker design file, imported from the CLIO, DATS / WT3, LAUD or Woofer Tester 2 measurement systems, or it can be loaded from BassBox Pro's extensive driver database. Like many windows in BassBox Pro, the Driver Properties window uses tabs to organize the information. Three of its six tabs are displayed below. The first illustration shows the 'Configuration' tab where the number of drivers and their mechanical and electrical configurations are set.

Notice above that the mechanical configuration settings include compound or isobaric and push-pull.

The second illustration shows the 'Parameters' tab containing the driver's Thiele-Small and electromechanical parameters. 'Net' parameters are displayed when more than one driver is specified. If the driver has a dual voice coil, separate parameters can be entered for each of the three voice coil wiring methods (separate, parallel and series). An 'expert mode' is available to analyze driver parameters for errors.

The third illustration shows the 'Dimensions' tab containing the driver's outer shape, piston type, dimensions and volume settings.

Not shown are the 'Description', 'Response' and 'External' tabs.

Design Many Different Box Types & Shapes
BassBox Pro models a wide variety of box types including closed, vented, vented with active HP EQ filter (B6), single-tuned and double-tuned bandpass and passive radiator boxes as shown below:

Twenty-two different box shapes are available as shown below:

Box Properties
The information about the box is contained in the Box Properties window. Three tabs are displayed below. They depict a single-tuned bandpass box with three chambers (using two drivers). The first illustration shows the 'Box Design' tab where the box type, shape, volume, tuning and dimensions are set. Notice that it includes a scaled drawing of the box. This drawing automatically updates in 'real time' whenever the box is changed.

The second illustration shows the 'Vents' tab which contains the vent parameters and dimensions. The vent parameters include the number of vents, their shape and end type. If a passive radiator box is selected, this tab will appear as the 'Passive Rad.' tab.

The third illustration shows the 'Parts List' tab with a scaled drawing of each box part, a list of dimensions and, if appropriate, cut angles.

Not shown are the 'Description', 'Damping' and 'Interior' tabs.

Acoustic Properties
BassBox Pro accepts two different types of acoustic data. It can be entered manually or imported from several popular measurement systems (B&K, CLIO, IMP, LMS, MLSSA, OmniMic, Sample Champion, Smaart, TEF-20 and TrueRTA). This acoustic data is added to relevant graphs to improve their accuracy.

The acoustic response of the listening environment is entered into the Car/Room Acoustic Properties window (shown below). For example, the acoustic response of a motor vehicle interior can be entered to show how a speaker will sound to a passenger inside a car.

The normalized acoustic response of the driver is entered into the 'Response' tab of the Driver Properties window (not shown). The driver's acoustic response is normalized to its predicted Thiele-Small response.

Performance
BassBox Pro provides nine graphs to evaluate the performance of a speaker design. The Normalized Amplitude Response, System Impedance, Phase Response and Group Delay graphs are provided for small-signal analysis. The Custom Amplitude Response (shown below), Maximum Acoustic Power, Maximum Electric Input Power, Cone Displacement and Vent Air Velocity graphs are provided for large-signal analysis.

The graphs include numerous options. There are two graph modes: a combination graph window which displays graphs one at a time for computers with low VGA resolutions and separate graph windows for simultaneously displaying multiple graphs for computers with higher XGA resolutions.

The graphs can display the 'pipe' resonance of vents, the estimated piston band on-axis amplitude rise of a driver and the estimated diffraction response shelf (of selected box shapes) that can result from the front-panel circumference of the box.

Other options include two vertical and two horizontal scales, seven graph memories, cursor and an export (copy) function via the Windows clipboard.

Custom Printouts
Custom printouts can be created which include the box and driver parameters, a three-dimensional box drawing with internal and external dimensions, a parts list with two-dimensional box part drawings, dimensions and cut angles, an English fraction-to-decimal conversion table, wiring diagram with an external network parts list and nine graphs. A custom logo or graph can be imported and printed in the title block.

Test Procedures
Driver and passive radiator test procedures are included in the program to help you measure most Thiele-Small parameters. (Requires test equipment such as: sine wave generator, frequency counter, power amplifier, 1000 ohm 2-watt resistor, voltmeter, ohmmeter, test box.)

Passive Network
A passive network (high-pass, band-pass or low-pass filter, impedance EQ network and/or L-pad) can be entered or imported from X•over Pro to display the system impedance.

Compatibility
BassBox 6 Pro can open speaker design files from BassBox 6 Lite, Eminence Designer 1 and older versions of BassBox (versions 5.1, 5.0, 4.0 and 3.0). Passive network information can be imported from X•over 3 Pro.

BassBox Pro includes:
A BassBox Pro license includes an installation CD with the BassBox Pro computer program, driver database and online manual. A beautiful 364 page printed manual is also included.

System Requirements
BassBox 6 Pro requires Microsoft® Windows® and has broad compatibility with 64-bit and 32-bit versions of Windows 10, 8.1, 8†, 7, Vista and XP. The program requires a minimum of 36 Mbytes of free hard disk space and a CD-R compatible CD-ROM, DVD or Blu-ray drive. Also, the Arial and Symbol TrueType fonts must be installed (both fonts are a standard feature of Windows). BassBox 6 Pro is not available for download.
