Martin Logan Balanced Force subwoofers.
BalancedForce® Series
Subwoofers engineered specifically to match the speed, accuracy and big sound of an electrostatic loudspeaker. BalancedForce subwoofers feature superior low-frequency technology, and ultra-heavy duty construction, to effortlessly bring the deep, deep down you desire.
Building on the groundbreaking technology of the original Descent,
BalancedForce 212 incorporates new features and enhancements that
simplify system integration while improving performance. Its signature
two-driver, force-canceling configuration virtually eliminates
bass-blurring cabinet resonance. And each rugged, custom-built
aluminum-cone driver is driven by sophisticated DSP-based, high-power
amplifiers. The result is dynamic, unrestrained output to the very
lowest frequencies, yet with clarity and definition approaching that of
electrostatic transducers.
Ultimate Performance Subwoofers
Chances are you've read or heard at some time that adding a subwoofer to a system built around electrostatic speakers is nearly impossible. Although that's not necessarily true (and we have the subwoofers to prove it), the idea is grounded in experience. For many years subwoofers and electrostats did not blend very well. Turn on the sub and maybe you got the deeper, stronger bass you were looking for but that wonderful electrostatic snap and midrange clarity were, if not gone, now smeared and disconnected.
Our goal, when we began our first subwoofer project, was to deliver the good stuff — deep, tight, powerful bass — and none of the bad. We wanted to build subwoofers that, when combined with ultra-fast electrostatics or conventional cone speakers, would blend seamlessly to the very bottom of the frequency extreme. BalancedForce subwoofers are the full realization of years of engineering by the MartinLogan team combined with the latest innovations in advanced digital signal processing, amplification, electrical system designs, and room correction.
Custom Low-Pass Filters for
Individual Loudspeaker Models
Custom tailored low pass filters are available for nearly every floor standing MartinLogan loudspeaker released in the last 30 years. These optional custom filters adjust the subwoofer's low pass settings to seamlessly blend with the roll-off characteristics of individual loudspeaker models. Filters are easily installed via a user-friendly process involving a USB thumb drive and are available for free download. Many unique filters are currently available and additional filters will be added as new speakers are released.

Rel S3 SHO

Habitat 1

S/5 Super high power

Fit your Space
Habitat1 is a brilliant new concept that takes sub bass to new levels by incorporating the room, your Habitat, into its design. It is common in design circles to speak of taking the room into account, but never has the complete system approach employed by REL been utilized so utterly to one singular purpose. Perfect, deep bass that emanates almost invisibly from somewhere hidden within the room.

Power and Performance
The beautifully balanced S/3.S/3 SHO derives from the flagship S/5 SHO and offers a more compact footprint and much of S/5 SHO performance for use with either slightly more modest systems or rooms that cannot handle the power and output of S/5 SHo.

Qualitatively, it is the equal of S/5 SHO, sans the grand scale, power and majesty of its larger sibling.Beautifully balanced, S/3 SHO offers powerful, incisive and beautifully balanced performance.
The Serie S Flagship
S/5 SHO exceeds the mandate for mid-level models and crosses this model into true reference quality. S/5 SHO produces exceptionally low bass with tremendous impact and speed. Even difficult-to-render instruments such as pipe organs are dealt with effortlessly.

Large scale, high end 2-channel systems make a perfect pairing for S/5 SHO and grand theaters are ideal. Medium to grand rooms are appropriate.

T+A Criterion TC610 W Sub-Woofer

This active sub-woofer is yet another completely new development. Its amplifier is based on the overall design of our switch-mode output stages of discrete construction (they do not employ standard off-the-peg chips), which have already proved to perform superbly in our TCI active loudspeakers. The amplifier offers unsurpassed dynamic abilities and speed, and its power reserves and sound qualities are equally impressive. An output of more than 1000 Watts is available, and the amplifier is directly coupled to a pair of special 26 cm drivers of very low resonance frequency, capable of enormous excursions. The net result is an exceptional standard of deep bass reproduction and tremendous stability under load – a combination which has never been achieved before. We have equipped the active unit with a modern signal processor which controls the whole system; automatic calibration to match the listening room is possible using the microphone supplied in the set.
The calibration software, which is an in-house development, also offers the option of using a PC to calibrate the sub-woofer’s output and frequency response to suit the listening room to match individual preferences. The remote control handset included with the speaker has many useful set-up facilities, such as user-variable limit frequencies and continuous level and phase control from the listening location.
As you would expect, the TCD 610 W also features a sophisticated protective circuit and automatic power-on facility.
