Overview
The JBL JBLL10CSWALAM is a floor standing powered subwoofer with a 10 inch driver, 250 watts of power, RCA connectivity, and a Walnut finish, weighing 11 lb.
As a subwoofer rather than a full TV or soundbar, this unit is meant to add low frequency output to an existing stereo or home theater setup through its RCA input, not to run on its own. The Walnut finish and floor standing design point toward a piece meant to sit visibly in a living room rather than hide behind furniture.
- 10 inch driver, 250W power rating
- RCA connectivity
- Floor standing design
- Walnut finish, 11 lb
Who it's for
Home theater or stereo owners who want to add bass through an RCA subwoofer input and prefer a wood finish over black plastic. Not a standalone speaker, so it needs a receiver or amp with an RCA subwoofer output.
Pros and cons
- 10 inch driver with 250W of power
- Walnut finish suited to visible placement
- Light at 11 lb for repositioning
- RCA only, no wireless connectivity listed
- Requires a receiver or amp with a subwoofer output
Performance notes
A 10 inch driver at 250 watts is sized to fill in low frequency output for a mid-size room, connecting through a single RCA line rather than wireless or speaker-level inputs. At 11 lb, it is light enough to reposition without much effort despite the floor standing design.
