Overview
The Klipsch SPL-120 is a tabletop mounted subwoofer with a 12 inch driver and 600W power rating, connecting through RCA and weighing 45 pounds in a black finish.
Klipsch built the SPL-120 around a single large 12 inch driver rather than multiple smaller drivers, a common approach for pushing low frequency output from one enclosure. RCA is a standard analog connection for subwoofers, meaning it will pair with most AV receivers and amplifiers that include a subwoofer output.
- 12 inch subwoofer driver
- 600W power rating
- RCA connectivity
- Tabletop mount, black finish, 45 lb
Who it's for
Fits a home theater setup wanting stronger bass than built in TV or soundbar speakers provide, with a receiver that has an RCA subwoofer output. Less suited to a wireless-only setup, since the listed connectivity is RCA rather than a wireless link.
Pros and cons
- 12 inch driver sized for deep bass extension
- 600W power rating
- RCA connectivity works with most AV receivers
- 45 pounds, not easily moved once placed
- RCA only, no wireless connection listed
Performance notes
A 12 inch driver moves a larger volume of air per stroke than smaller drivers, which generally supports deeper bass extension at the cost of a larger cabinet, reflected here in the 45 pound weight. The 600W rating and tabletop mounting point to a unit meant to sit on the floor or a low platform near the front of a room rather than being wall mounted.
