The volume of air a subwoofer displaces is the direct measure of how loud it can play: the M7-12IB displaces more than twice as much as most 10-inch subwoofers, thanks to oversized parts and a very powerful motor.\u003c\/p\u003e\n\n\u003ch3\u003eParameters\u003c\/h3\u003e\n\n\u003cp\u003eFor system designers: free-air resonance 35.34 Hz, Qts 0.791, Vas 56.35 litres, linear excursion Xmax 18.5 mm, effective piston area 0.052 square metres, DC resistance 3.543 ohms.
