Professional Collection Pendants provide superior bass and dispersion in an ultra-modern enclosure. The secret is our rearfacing tuned bass radiator that virtually doubles the cabinet size when it comes to low-end reproduction. We have the same premium transformers and Silk DPSD ™ tweeters as the rest of our Professional collection, ensuring a smooth, consistent sonic signature for all of your installs, regardless of style or placement. They come standard in black and white with three woofer/ tweeter compliments and one subwoofer.
