In-Wall Subwoofer with an Open Back Design
What’s the difference between Dynamo IW-O and IW-S? The Dynamo IW-O uses the same retrofittable size, and dual 8” woofer configuration as the IW-S, but with an open back design instead of a sealed, fire rated enclosure. The open back of Dynamo IW-O means more sound will transfer into the wall (which could cause some noise complaints from other rooms), but with the tradeoff of deeper bass extension and higher output potential than IW-S. IW-O also has an available “High Output Back Box” accessory for when a mixture of sound control and higher output is desired.
Dynamo IW-O gives you flexible installation options. Choose to use it in its default open wall cavity configuration and you have an affordable, easily retrofittable, high output subwoofer solution. For new construction projects, or when drywall repair isn’t an issue, the optional HOBB (High Output Back Box. Sold Seperately) acoustic backbox provides a large enclosure volume to let the Dynamo IW-O stretch its legs, while providing acoustic control to reduce sound transmission through the wall.
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.
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 Series
With 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-O expands the offerings in our highly acclaimed Dynamo Subwoofer series. With a minimalist look, the Dynamo IW-O 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.Explore the MP500
