Overview

The Martin Logan Dynamo IW-O is an extremely capable in-wall subwoofer, bringing legendary Dynamo performance without taking up valuable floor space.

The Choice Is Yours

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.

Bass Without The Bulk

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.

Distributed Audio Made Easy

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.

Practical Performance

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.

Other Features

  • Ultra Rigid Stamped Steel chassis and baffles and die-cast aluminum clamps add strength and rigidity for better bass performance, and more durable installation.
  • Magnetically attached grille: Easily reveal or hide the performance whenever you like.
  • Premium-grade components include high-power rated resistors, capacitors and heavy gauge wire inductors.
  • Optional (sold seperately) High Output Back Box available for when sound control is desired. The IW-O with optional back box will requires new contruction or drywall repair to be performed. If both sound control and retrofit sizing is required, take a look at the Dynamo IW-S.
  • Nickel-plated, spring-loaded binding posts feature a larger wire hole to accept higher-gauge wire or banana plugs.

The Hidden Alternative

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.

A Perfect Match

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.
