Overview
Klipsch builds this powered subwoofer around a big woofer inside timber walls, supplies a grill, manual and power cord, and connects to a receiver over a wired RCA link.
The listing covers the useful basics, including output power, warranty terms and a remote control with bass boost. It also contains confused entries such as vehicle type, a Wi-Fi protocol and a range in meters, which do not fit a home subwoofer.
Who it's for
Home entertainment rooms with floor room for a large cabinet suit this sub, especially alongside an existing receiver. Buyers in small apartments or anyone wanting a wireless link should look at a smaller or wireless model.
Pros and cons
- Remote control and bass boost
- Grill, manual and power cord included
- Split warranty on woofer and amp
- Several listing entries look wrong
- Large cabinet and heavy
- Frequency response given as a single figure
Performance notes
Low-frequency output rises with woofer size and amplifier power, and the wood cabinet adds rigidity. Corner placement raises level while open walls thin it. The remote and bass boost let level be adjusted from the seat, but a room still decides how deep the bass feels.
