Our Compact 8" (20cm) Cellular Bass® module is a patented Front Loading Acoustic Compression Chamber and Waveguide that pumps out the deepest sub bass content without the boom and distortion of bass reflex loudspeakers.

Model CBLS 1 is our passive sub - bass speaker with a compact Cellular Bass® module built for home entertainment systems.                

Model CBLS 3 is designed as a full range 3 - way enclosure with 8-Ohm electro magnetic tweeter, 8" (20cm) midrange, 8" (20cm) Cellular Bass® module and crossover. 

The patented Sub Bass Compression Loudspeaker System features a close proximity front baffle and a moving element acting as a diaphragm to resonate air in a compression cavity.

This layout is extremely effective in damping boom resonances from the enclosure that would otherwise exit via the diaphragm and colour the output. The diaphragm is part of a loudspeaker formed into a flat face driver and tests have established the ideal frequency range and power limits for this design.

Compressing both the boom resonance of the closed box and the free-air resonance of the special sub-bass driver produces a broader and flatter frequency response graph that extends across 120Hz to 20Hz, with greatly reduced colouration across it's sub-bass band.

Our compact sub bass is proven to extend the low frequency range by employing front and back Acoustic Compression Loading Systems.

There is a need for a bass reproduction system that gives a superior performance compared to the compact bass reflex designs commonly found in home entertainment systems.

The patented “Acoustic Compression Loaded System” drives sub-bass outwards from the compact unit with the efficiency to deliver clear fundamentals at output power levels you set with ease.

These unique features pump sub-bass waves from the outlet vents into your listening space whilst high acoustic resistance blocks room reflections from reaching the driver.

Our compact Compression Bass Loudspeaker System is the best replacement for bass reflex units. It will bring a new and pleasurable experience to your choice of entertainment.

We aim to raise the awareness of audiophiles to the Compression Loading technique for acoustic resistance loading of sub woofers. This is a critical requirement for reproducing a life-like bass acoustic image in smaller home entertainment spaces.

Our research and development was focused on home entertainment where 10 Watt bass reflex boxes are often small versions of a 1000 Watt model.                                     

It is well known that these small boxes do not work like a true bass reflex and stop producing clean bass output below their boom box resonant frequency. The poor performance is due to a lack of acoustic resistance loading of the sub woofer.

We have successfully corrected the acoustic loading deficiencies to get a superior sub bass performance in a domestic environment.

The Compression Loading System is our Cellular Bass® patent and it has been further developed as a 4 x Cellular Bass® speaker to achieve a high SPL output for the public performance market.

Air is very thin stuff, and bass vibrations are relatively slow. For a slow-moving bass loudspeaker cone to have much effect on the air, it has to be large and it has to travel back and forth a long way.

It may seem as though a high-power woofer is a powerful, rugged, macho device, but in reality it’s a piece of paper frantically flapping in the breeze, trying to make a difference. It’s not easy to make that kind of thing linear.

By way of comparison: under water you can get loud bass down to 20Hz from a 2-inch diameter woofer.
