Our take on the Klipsch SPL-150 800W Subwoofer
The Klipsch SPL-150 is a 15-inch powered subwoofer with a 800W class D amplifier, built for home theater and music systems that need serious low-end output. It uses a front-firing Cerametallic woofer in a bass-reflex cabinet with a rear port, and adds Klipsch's WA-2 wireless kit compatibility so it can sit away from the receiver. It suits large rooms and movie-first setups; smaller rooms and apartment neighbors will find its size and output hard to tame. Against sealed 12-inch subs it digs deeper and plays louder, but it is a big, heavy box that needs space and careful placement.

What reviewers say
Owners of the SPL-150 generally describe it as a high-output sub that adds real weight to movie soundtracks and holds together at loud levels. The recurring complaints are its size and weight and the boominess that comes from a rear-ported box in a small room.
- Bass outputPraisedOwners say it delivers deep, forceful low end that gives movie soundtracks real weight.
- Size and weightCriticisedBuyers call the cabinet large and heavy, making placement and moving a two-person job.
- Room boomMixedSome owners report boomy bass in small rooms until level and crossover are dialed back.
Questions and answers
- Is the SPL-150 good for movies or music?
- It is strongest with movies, where its 15-inch driver and 800W amplifier add weight to explosions and scores. It also works for music if you keep the crossover and level modest.
- How big a room does it suit?
- It is built for large rooms and open living spaces. In small or shared-wall rooms its output is hard to control and bass carries easily.
- Can it connect wirelessly?
- Yes, with Klipsch's WA-2 wireless subwoofer kit, which replaces the cable run to the receiver. The kit is sold separately.
- Does it need space behind it?
- Yes. The port is on the rear, so leave clearance from the wall to avoid chuffing and boomy bass.
- What is in the box?
- The subwoofer itself with its power cord and basic documentation. A subwoofer cable and the wireless kit are not included.
- How does it compare with the SPL-120?
- The SPL-150 uses a larger 15-inch driver and more amplifier power, so it plays deeper and louder. The SPL-120 is smaller and easier to fit in a modest room.
