Definitive Technology IW Sub Reference
sku# 735IWREF
Get big bass, save space If you want a solid home theater system, you definitely need a powerful subwoofer. And if you're looking for a bigger boom, these can end up getting pretty big. The Definitive Technology IW Sub Reference is a space-saving solution that brings your entertainment to life with high-impact bass. This in-wall sub has a 13" long-throw woofer paired with a 13" passive radiator, giving it a ton of surface area for its size, but with greater control and accuracy than a single-woofer sub.
