What customers say
Customers consistently praise the Martin Logan BalancedForce 210 for its exceptional bass control and musicality, establishing it as a reference subwoofer. The dual opposing drivers produce bass that is remarkably tight, fast, and free from cabinet resonance or boom. Reviewers emphasize its surgical precision and effortless depth, noting its seamless integration with high-end speakers. While the unit is substantial in size, the resulting articulate low-frequency performance is universally deemed worth the investment. The sophisticated room correction technology is highly valued for achieving a flat frequency response, solidifying its position as a benchmark in high-fidelity audio.
Know before you buy
The BalancedForce design uses two opposing drivers that fire in opposite directions. This cancels out cabinet vibrations, ensuring the subwoofer stays stable and produces clean, distortion-free bass rather than rattling the enclosure.
Yes. The BalancedForce 210 allows for simultaneous connections to both LFE (for home theater) and 2-channel sources. This means you can maintain separate settings for movies and music without needing to swap cables.
It is specifically engineered to integrate with high-resolution speakers like MartinLogan’s electrostats. Its sealed cabinet design provides the tight, fast transient response necessary to keep pace with the speed and transparency of electrostatic panels.
Room correction is supported via the optional Perfect Bass Kit (PBK). This kit uses a microphone and software to measure your room's acoustics and automatically adjust the subwoofer's output to eliminate peaks and dips caused by your specific environment.
The controls are discreetly located on the top of the unit, hidden beneath a smoked glass panel. This keeps the aesthetic clean while ensuring you can easily adjust your settings without needing to reach behind the cabinet.
A sealed cabinet provides a more controlled and accurate bass response compared to ported designs. While it may not offer the same 'boom' as a ported sub, it delivers deeper, tighter, and more musical bass that is easier to blend with your main speakers.
