Regardless of the color of the drivers and enclosure, the only visible parts - once installed - will be white (white grille and trim, if this item is trimmed).
MartinLogan Dynamo IW-O
Non-powered in-wall subwoofer
Requires the optional back box DYNIWHOBB (which is very large, so it's only appropriate for new construction. If you're retrofitting, use the Dynamo IW-S instead of the IW-O).

IW-O Back Box
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 Separately) 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.
