This Klipsch subwoofer is the most powerful in the Reference series, aside from some of the newer models. Its 12-inch front-firing driver produces low frequencies brilliantly with minimal distortion. 

Thanks to the all-digital amplifier, it can recreate sound signals without losing quality. So you get the bass and sound just how the engineers have meant for it to be heard. You can place it anywhere in the room per your needs, as the front-firing port allows positioning flexibility. 

This one only allows wired input, but you have both line-level and LFE RCA jacks. It’s easy to be paired with other speakers and blends the bass with the sound for a cohesive auditory experience in home theater. 

The sub has a streamlined modern aesthetic with LED for on/off state. The body is made of MDF, a sturdy material but not overly heavy. The black finish on the wood makes it a versatile speaker that blends with other components of the home theater system effortlessly.
