Dayton Audio B652 Bookshelf Speakers Black Cabinet Great Sound! Overview Get the power and punch of the original awesomely-affordable Dayton Audio B652 speakers, now with the pristine high frequency performance enabled by AMT (Air Motion Transformer) technology! Dayton Audio B652-AIR speakers take a big step up, thanks to the addition of a higher-quality AMT tweeter. The AMT's folded Kapton ribbon diaphragm moves more air but with less effort and distortion, for purer and satisfyingly dimensional sound. B652-AIR speakers sound better than ever, yet retain the original B652's same compact size. The B652-AIRs also share the efficiency that delivers big acoustical output without requiring a huge amplifier…and they're still extremely affordable! In fact, the Dayton Audio B652-AIR is the most reasonably priced speaker using AMT technology. All of the other original-B652 speaker's features are still present: a tight-sounding 6.5" woofer in an optimally-damped sealed wood composite enclosure, an included keyhole hanger bracket, quick-connect terminals, non-marking rubber feet, and a removable fabric grill that doesn't get in the way of the B652-AIR's improved audio quality. We've even included the speaker cables! Compatible with receivers that support 4-8 ohm speakers.
