A:Answer Assuming you are referring to L7S10 Solo-Baric 10" Subwoofers? They are the only subwoofers in the L7 line that carry a 1200 watt Peak rating. If so, then yes, the CXA 1800.1 will be plenty of power to drive a pair of those 10" subwoofers. The 44L7S104 subwoofer is rated for 600-watt RMS power handling with a 1200-watt Peak. Please make sure your gains are set properly and do not operate your amplifier into a clipping state and you should be good!
