Selling a pair of like new condition PARADIGM ADP-350 SURROUND SPEAKERS. No issues whatsoever. All drivers in like new condition, cabinet condition also like new. The ADP-350 is a dipole surround loudspeaker that utilizes the same tweeter and bass/midrange drivers as the CC-350 and incorporates Paradigm's Reverberant Soundfield technology. Two pairs of the tweeter and bass/midrange drivers fire in opposite directions that are said to be "optimized with differing radiation patterns at various frequencies to ensure both timbre accuracy and a very large reverberant soundfield." The speaker measures 13"H x 11.4"W x 8"D. Its frequency response is rated at 75Hz to 20kHz (reverberant soundfield), sensitivity is 87dB, and the recommended amplifier power is 15 to 175 watts.
