Visual Sound Panaray 502 B 扬声器

Bose Corp.","The Panaray® 502®B loudspeaker delivers low-frequency response down to 55Hz for installations requiring additional bass-extension. Bose® patented Acoustimass® speaker technology launches low-frequency sound on two air masses. This filters out audible distortion, making the low-frequency sound is non-localizable. As a result, the enclosure can be placed where it is most convenient - even hidden out of sight. With a frequency response of 55Hz-150Hz, the Panaray® 502® B bass loudspeaker is engineered to match acoustically with the Panaray® 502®A speaker systems.
