Beale Street Audio 70/100V Commercial Audio Ceiling SpeakerWhile most 70/100V in-ceiling speakers only give passable performance, Beale Street has created 70/100V speaker that sounds just as good as their professional line of 2-way audio speakers. This speaker is fully baffled, but instead of just a top hat, this enclosure features their Sound Vortex Technology that uses a unique sprial in the enclosure to create three tuned ports that not only add bass but also a wider dispersion pattern for fuller sound. To make this speaker complete, Beale Street used a 3/4" aluminum tweeter capable of reproducing frequencies of 24kHz.
