Pros: A ported 10 inch subwoofer with app control and room correction you can adjust from your seat, now discontinued. Its 300W RMS amplifier averages 113.9dB from 40 to 80Hz and is rated from 24Hz. ARC room correction is included. The Active Ridge Technology surround lets the driver move farther.

Cons: Deep output falls off, with 98.2dB at 25Hz and 82.7dB at 20Hz, so it is weak for the lowest movie effects. It is discontinued, so you must buy used. At 19.1kg and 417mm tall it is a mid sized cabinet for a 10-inch sub, and it costs a lot for that output.
