For my room, testing this next to a SVS SB-4000, (SVS costs more) this sub out preformed the SVS. The DN15 has all the benefits of a ported sub without the chuffing. Warning though, this sub weighs over 150lbs. Not the easiest unboxing experience and my first shipment attempt arrived damaged.

Beautifully designed subwoofer, very heavy and well-built. Comes with a simple but nice remote that is straightforward and easy to use. The bass is amazing, you can both feel and hear the quality it puts out, very pleased.
Wow. Listened to a SVS Sub and then listened to this one DN12 and the bass that comes out of this is very impressive. Ordered it, hooked it up at home and it will shake things that you would not expect. We really like the sound thst comes out of this little sub Will be buying a second one soon.
This is a nice upgrade from the Def Tech Supercube that served me well for years. This sub provides room filling deep base at a reasonable price point. It's helped take my movie watching to the next level. Base heavy scenes like the opening of Star Wars Episode III and the race in Ready Player One really steal the show.

A:AnswerHello, first be sure to turn the LFE out to LFE plus Main in the receiver. For instance with Denon, if the front speakers are set to large the bass output will need to be changed to LFE plus Main. Further assistance please contact us at https://support.definitivetechnology.com/
