Everyone knows that the easiest way to get low, rumbly bass is to use a larger driver. Enter the Studio Reference Sub 15! This guy fills the room easily, and with the option to use the Perfect Bass Kit and it's on board DSP, most of the traditional complications of using a large diameter woofer are overcome.
Out of the box, the sheer amount of air this thing can move is fairly impressive, but once you do the PBK setup, coupled with an NAD Audessy setup, the results are well worth having a listen to! Currently fired up in Demo Lounge 3, make sure to come by before our neighbors complain.
