Overview
Built for tight installs, the JBL K951094 is an 8 inch subwoofer rated at 125 watts, connecting via aux or RCA and weighing under a pound.
Despite being filed under TV & Home Theater subwoofers, the under-seat mounting spec listed here is more typical of vehicle audio installs than a floor-standing home theater subwoofer, so it's worth checking the intended install space before buying. RCA and aux inputs cover both car head units and basic home receiver setups alike.
- 8 inch driver
- 125w power rating
- Under-seat mounting
- RCA and aux connectivity
Who it's for
Buyers who need a subwoofer that fits a tight space, such as under a seat, in a small footwell, or inside a compact cabinet, rather than a full-size floor unit. Not for anyone wanting maximum room-filling bass output.
Pros and cons
- Compact under-seat mounting
- RCA and aux inputs cover multiple sources
- Light at 0.99 lb
- Under-seat design suits tight spaces over full-room bass
- Category listing as home theater may not match its car-style mounting
Performance notes
The 8 inch driver in an under-seat enclosure trades maximum output for a small footprint, with a 125w rating and RCA or aux inputs covering line-level connections from a receiver or amp.
