Looking for an affordable home theatre sub that is also tight and musical? L22 uses our proprietary servo design to gain low frequency clarity and articulation. For home theatre use, L22 uses two 12″ driver to deliver low frequency impact and output that home theatre demands. While many of our competitors limit their best technology (such as servo) to their top level models, we wanted to make Direct Servo affordable, so we’ve held nothing back. As a result, you get the tight and music bass you wouldn’t normally expect from a subwoofer at this price range.
