Proficient Audio Solutions FS10 Protégé 10” Dual-Drive Powered Subwoofer with 250-Watt Amp (Black) 
Mid-size maximum muscle! The Proficient Audio Solutions Dual-Drive Subwoofer offers great bass without taking up too much space. It can shake the floor but goes unnoticed in most settings. With a 10” driver, 250-watt RMS, and extra-wide surround it’s equipped.
Features
This subwoofer’s extra-wide surround increases the cone excursion, allowing it to move more air and pound out deeper bass. The 250-watt RMS call D amp powers the driver and a 10” passive radiator reinforces the lowest notes. This creates a smaller sub with more than 10+ dB extra deep bass output than other models.
