Brand: Polk audio
The Polk Audio SDA-2 is a high-performance floor-standing loudspeaker that was introduced in 2009 as part of Polk Audio's existing SDA (Special Dyamic Assembly) series. The SDA-2 features two 1-inch Titanium dome tweeters with Polk's patented Power Port bass-loading technology, which increases low-frequency output and reduces turbulence for smoother bass response. The cabinet is made of MDF and is both braced and acoustically treated to minimize resonance and distortion. The midrange driver is a 6.5-inch polypropylene cone with a rubber surround for accurate range reproduction. The Polk Audio SDA-2 is designed to give audiophiles a realistic and dynamic listening experience, making it an excellent choice for audiophiles who demand high quality sound.
