Know before you buy
No, this is a passive subwoofer. You will need to pair it with a separate, external amplifier to power the unit.
Yes, the grille is designed to be paintable. This allows you to customize the finish so the subwoofer blends seamlessly into your wall decor.
The unit is fully enclosed, which simplifies installation by ensuring consistent sound quality regardless of the wall cavity. However, you should verify that your wall depth can accommodate the enclosure dimensions of 25.13 x 14.38 inches before cutting.
Despite its discreet profile, the 13-inch driver and matching bass radiator are engineered to deliver a frequency response down to 14Hz. This provides deep, impactful low-frequency output comparable to many traditional floor-standing subwoofers.
While it is primarily designed for home theater applications, it can be used in any custom audio setup. Just ensure your external amplifier is capable of driving a 4-ohm load.
