Description

BalancedForce 210 delievers powerful bass with electrostatic-like detail to any audio system, whether for high-end stereo music listening or multi-channel home theater. Its two-driver, force-canceling configuration virtually eliminates cabinet resonance and the resulting bass blur that plagues conventional subwoofers, while a sophisticated DSP-based amplifier ensure the purity and accuracy of the sound from the drivers.

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.

BalancedForce® Alignment

Opposing Aluminum Element Woofers for Deep, Clean Bass

Dual low-distortion woofers pair a high-power magnet structure with 10- and 12-inch aluminum cone diaphragms to deliver huge excursion and sound output while preserving minute bass details, all without a hint of distortion. The cone material’s exceptional damping properties ensure the smooth, non-resonant response necessary for seamless blending with high-resolution full-range loudspeakers.

BalancedForce 212

These woofers, spaced 180 degrees apart in a ‘BalancedForce’ configuration, operate in exact opposition, to nullify distortion causing cabinet vibrations and deliver pure bass energy. Traditional subwoofer enclosures suffer from an equal and opposite reaction to the cone’s movement, generating acoustic vibrations within the cabinet. You feel this by touching the cabinet. Although the “physics” of this phenomenon actually cause a subwoofer cabinet to resonate or even dance, most subwoofer designers apply weight or mass to the cabinet to minimize such disturbances, but still leave one byproduct—”smeared bass”. BalancedForce is an elegantly simple solution that removes the variable of cabinet vibration contributions from the acoustic equation.

Amplifier Design

Advanced Ultra-Efficient D-Class Amplifier

BalancedForce subs match powerful proprietary switching amps with incredible woofer drivers resulting in tightly defined bass while keeping distortion at the lowest possible levels. The BalancedForce 210 features an 850-watt class-D switching amplifier capable of a 1700-watt peak operating at over 90% efficiency. BalancedForce 212 features dual 850-watt amplifiers (one for each woofer) with a total system power of 1700-watts (3400-watts system peak).

Low-noise, high-power transformers and switching power supplies feature high-quality MOSFET transistors, noise-suppression networks, and control circuitry to provide tremendous levels of current with extremely low levels of distortion. Split power supply rails minimize distortion while maximizing switching efficiency. Military grade glass epoxy circuit boards, temperature sensors, and protection circuitry guarantee quality sound and reliable trouble-free operation.

PBK Room Correction & 25Hz Level Control

Although correct placement plays a key role in optimizing subwoofer performance, positioning a subwoofer often requires compromises. The optional MartinLogan Perfect Bass Kit (PBK, sold separately) uses a computer and microphone to listen throughout the listening environment and tailor the sub’s performance to the unique acoustic properties of a room—resulting in clean, powerful bass down to the lowest frequencies.

Additionally, a built-in 25Hz level control allows listeners to adjust subwoofer output by ±10dB and compensate for excessive room gain by cutting output in the 20- to 30-Hz range, or to accentuate the feeling of deep-bass energy by augmenting those frequencies.

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.

Beautiful Finishes

High-gloss black cabinets and top trim are standard. Top trim is available in a variety of optional high-gloss, hardwood, and real-wood veneer finishes.

Sealed Cabinets

Although ports are a convenient and cost-effective way of increasing low-frequency output, their reliance on resonant energy impairs bass quality. The BalancedForce subwoofer’s sealed system exhibits less transient-blurring group delay while maintaining smooth, consistent response, regardless of music or movie source material.

Martin Logan

Founded in the late 1970s, Martin Logan has been a consistent leader in electrostatic speaker design. With hands-on design and engineering, each model provides high-quality audio like no other. More specifically, the ESL series is one of the brand’s most highly distinguished releases to date. The mission of Martin Logan is to find the “Truth in Sound” by designing speakers that can “render the most complex musical passages as faithfully as a prism disperses the color spectrum.” Overture displays and offers many speakers from the Martin Logan Reserve ESL Series, featuring the Ethos, Spire, Summit X, and their “flagship” CLX. This prestigious series has taken the world by storm, providing some of the best audio quality for home entertainment systems. In addition to the brand’s speakers, their subwoofers are also top-notch, producing a considerable amount of power. Overall, Martin Logan has some of the most powerful and dynamic electrostatic speakers as well as other distinguished speaker systems. Overture is a proud dealer of Martin Logan products, selling customers the best speakers from Martin Logan. Interested in purchasing a new Martin Logan component?
