The Polk Audio Vanishing Series and Polk Audio VS 700-LS ‘B-Stock’ in-ceiling surround loudspeaker employs a rear-mounted 5″ x 7″ Dynamic Balance mineral-filled polypropylene Cassini-Oval cone woofer, with rubber surround, for a smooth, consistent frequency response. The oval woofer is mounted at an angle in the enclosure, behind the midrange and tweeter, and ported out the front.
The Polk Audio VS 700-LS ‘B-Stock’ has a 2-1/2″ Dynamic Balance aerated polypropylene cone midrange. The aerated polypropylene cone is 20% lighter than conventional polypropylene, and 35% lighter than aluminum, to give you clear midrange and high efficiency. Polk Audio’s patented Dynamic Balance technology eliminates unwanted resonances.
Ring Radiator Tweeter
The Polk Audio VS 700-LS ‘B-Stock’ employs a 3/4″ Dynamic Balance ring radiator tweeter for detailed highs and superb imaging.
Wall Distance Toggle Switch
If you mount the in-ceiling loudspeakers closer than 2 feet from a side wall, the proximity of the surface can elevate the midbass response between 50 and 200Hz, causing a boomy sound. To compensate, the 700-LS is equipped with the Vanishing Wall Distance Toggle switch, located on the front panel. The filter adjusts the crossover to flatten the response, and tune out the boominess, without sacrificing the deep bass response of the speaker. The switch is labeled “Wall Dist.” with two positions: in (<2′) and out (>2′).”
