MartinLogan Dynamo IW-O High Output Back Box
This is the matching back box for the MartinLogan Dynamo IW-O open-back subwoofer (not included in this purchase)

This back box is very large, so it's only appropriate for new construction (except for rare exceptions).

Shipping weight: 21 lbs Shipping demensions: 16" x 6" x 51" As you can see, this back box is HUGE - but that's what makes it sound so good!! Since in-wall subs don't have quite the force of free-standing subs, most AV professionals recommend two in-wall subs for home theater spaces (which means two back boxes).
