In-Wall Subwoofer with a Sealed, Fire Rated Enclosure
Looking to add some bass to a system without the bulk of traditional subwoofers? Featuring dual 8” woofers, and an integrated fire rated back box, the Dynamo IW-S is one of the most flexible in-wall subwoofers on the market. It’s retrofittable size means you can even add it to existing construction without the hassle of drywall repairs. Blending performance with practicality, the Dynamo IW-S is perfect for a “zero footprint” Home Theater or Distributed Audio system.
Designed for quick installation into existing rooms without the need for expensive and time-consuming drywall repairs. The sealed, fire rated enclosure makes Dynamo IW-S suitable for a variety of residential or commercial applications, especially where sound control is desired.
Purpose-built for high output and low distortion from a compact, retrofittable enclosure. The dual, 8” High-Excursion Carbon-Fiber-Reinforced Polypropylene woofers provide more surface area than a 10” sub for powerful, accurate bass without the bulk. The integrated enclosure ensures consistent performance in any application while reducing sound transmission to other areas of the home.
Our MDA series amplifiers have made adding bass to whole home music systems easier than ever. For these distributed audio systems, the Dynamo IW-S can easily be driven off the bridged “subwoofer output” allowing you to take advantage of the MDA’s robust bass management, custom DSP profiles, and advanced ARC Genesis room correction for optimized performance in any environment.
Explore the MDA SeriesWith powerful bass and zero footprint, you get the best of both worlds, allowing you to add bass to any room without taking up valuable floor space.
Sometimes a traditional subwoofer just isn’t in the cards for every system. The Dynamo IW-S is the first in-wall model in our highly acclaimed Dynamo Subwoofer series. With a minimalist look, the Dynamo IW-S is a great way to have much of the performance of a standalone sub without the bulk. Bass you’ll notice, with a look you won’t.
In addition to the MartinLogan MDA series, the Dynamo IW subwoofers are compatible with the MartinLogan MP500 amplifier. The custom DSP presets optimize performance and our engineers even designed options to support running dual subwoofers off a single amplifier, making it easier than ever to get powerful bass in a stealth installation.
