Definitive Technology IW Sub Reference Passive in-wall subwoofer

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.

The IW Sub Reference’s enclosure is non-resonant to prevent unwanted vibrations so you can feel the onscreen action without knocking all of the family photos off your wall.

Match with the SubAmp 600

Definitive Technology  designed the 275-watt SubAmp 600 subwoofer amplifier (sold separately) to perfectly match this sub. Using them together guarantees you’re getting just the right amount of power for optimal performance.

This amp goes on a shelf or equipment rack, along with your receiver and other A/V gear. If you have a large room, or want more evenly distributed bass, install two IW Sub References and drive them both from a single SubAmp 600. The amp delivers 230 watts to each sub.

Importante note: To take advantage of the IW Sub Reference’s 5-year warranty, it should only be paired with the SubAmp 600.
