Loaded with custom technologies, the Definitive Technology Descend DN15 is a digitally optimized subwoofer designed for movies and music. It is outfitted with dual 15” Bass Radiators that are pressure coupled to the 15” driver and 1500W peak Class H amplification that deliver powerful bass with amazing speed, musicality, and control even at 20Hz. Featuring the unique 3XR Architecture with three-times the bass-producing surface area of traditional subwoofers, the DN15 performs like two 18” ported subs and delivers exceptional and clearer lows without any unwanted port noise distortion. Featuring Intelligent Phase Control enables you to tune the subwoofer to flawlessly blend with your home theater system. Built-in controls allow adjust volume, low pass filter, EQs modes (Flat, Deep and Loud), and phase control (0/180°) for optimum bass levels. A perfect complement to any home theater system, you can easily connect the DN15 via LFE or stereo line level RCA inputs (cables not included). Add another, same-model subwoofer to your home audio set up to dramatically improve realism, smooth out peaks and dips, as well as to get an even bass response for all your movies and music. Be at the center of action from any part of the room!
