Overview
A listener short on floor space gets deep bass from a football sized cabinet built around KEF's Uni-Core technology. Two force cancelling drive units run from a built-in Class D amplifier, and the sub plugs into a wall outlet and connects to the audio system.
Compact size lets the sub fit beside furniture in a small room while the listed frequency figure points to very deep bass. The cabinet is dense for its size, and the cable to the receiver or amplifier is not in the box.
Who it's for
Small rooms, desks and apartments are the setting, where a full size cabinet would crowd the space. Listeners who want a sub they can carry around easily, or who expect every cable in the box, should look elsewhere.
Pros and cons
- Compact cabinet for tight floor space
- Force cancelling drivers reduce cabinet movement
- Built-in Class D amplifier, no external amp
- App control listed
- No RCA cable listed in the box
- Heavy for its small footprint
- Wireless setup details not explained in the listing
Performance notes
Bass depth comes from the two drivers working against each other so cabinet forces cancel, letting a small box move air without shaking. The built-in Class D amplifier supplies the power, and room placement then shapes how much bass reaches the seat. Corners and walls reinforce low notes, so moving the sub changes the result.
