Overview
The Klipsch 1070640 is a floor-standing subwoofer with a 10-inch driver and 500 watts of rated power, built to add low-end bass to a home theater speaker system via an RCA connection.
At 55 pounds and roughly 25 inches tall, this is a dedicated bass unit meant to sit on the floor near a seating area or front speakers rather than tuck onto a shelf. The 500 watt rating and 10-inch driver put it in Klipsch's mid-size home theater subwoofer range, finished in the brand's ebony color option.
- 10-inch driver
- 500 watt rated power
- RCA connectivity
- Floor-standing design, ebony finish, 55 lb
Who it's for
Fits a home theater or stereo setup where the existing speakers or soundbar lack low bass and there's floor space for a standalone unit. Not for anyone needing a compact or wireless subwoofer, since this connects via RCA and stands on the floor.
Strengths and trade-offs
Drawn from this product's published specifications.
- 500W power with a 10-inch driver for real low-end output
- Floor-standing design suited to home theater rooms
- Heavy at 55 lb, not easy to reposition
- RCA-only connection, no wireless option
Performance notes
A 10-inch driver paired with 500 watts of power is built to move enough air for noticeable low-frequency output in movies and music, and the floor-standing format lets the cabinet's size contribute to bass extension in a way a shelf unit can't.
