The CSS LDW7 woofer is utilized in a parallel pair to achieve high output, ultra-low distortion bass that extends down to 30 Hz anechoic and 20 Hz in room. While only measuring in at 7” each, they can provide the output of a traditional 10” woofer pair thanks to a Klippel optimized motor with a full copper sleeve, generous motor venting, and low loss suspension system. However, hitting the deepest notes at high output with low distortion doesn’t come at the sacrifice of a monolithic speaker in your living space. The cabinet measures in at a svelte 10.5” at it’s widest point, with the baffle being only 8” wide.
