Also new from Paradigm are the in-wall PCS80SQ and in-ceiling PCS ADR, $299/each. I didn't get a chance to hear them but it's encouraging that Paradigm designed rack-mount amps especially for them, including the 300-watt X300 and 850-watt X850. My colleagues have already covered the 3000-watt Signature Sub 25, with its three-inch woofer excursion, but I thought I'd throw in a rear shot. Note the USB input which facilitates mic measurement, because if there's one component in your system you really need to dial in right away, it's the sub!
