About In Wall Subwoofers
Shop in-wall subwoofers for powerful, concealed bass in home cinema, music and architectural audio systems. Choose from individual passive subwoofers, dedicated amplifiers and complete in-wall subwoofer packages with compatible components.
Why Choose an In-Wall Subwoofer?
An in-wall subwoofer adds low-frequency depth and impact without requiring a conventional subwoofer cabinet on the floor. The driver is installed within the wall and finished with a discreet grille, making it ideal for media walls, living rooms and dedicated cinema rooms where appearance and floor space matter.
In-wall subwoofers can complement in-wall speakers, ceiling speakers or a conventional surround-sound system. They can improve the weight of music, make film soundtracks more immersive and reduce the strain placed on smaller main speakers.
What Do You Need?
Most in-wall subwoofers are passive and do not contain their own amplification. A complete installation will normally require:
- An in-wall subwoofer driver
- A compatible dedicated subwoofer amplifier
- A suitable enclosure or back box where required
- Speaker cable between the subwoofer and its amplifier
- An RCA connection from your AV receiver or compatible stereo system to the subwoofer amplifier
Check each model carefully because the required amplifier, enclosure and installation method vary. Our complete packages combine a compatible subwoofer and amplifier, providing a simpler option if you are starting a new installation.
Choosing the Right In-Wall Subwoofer
Before ordering, check the wall cavity depth, cut-out dimensions and whether a dedicated back box is included, optional or required. An 8-inch model can suit smaller rooms and music systems, while larger 10-inch or dual-driver models generally provide greater low-frequency output for larger rooms and home cinemas.
Using two in-wall subwoofers can also provide more consistent bass across a larger seating area, although the ideal quantity and position will depend on the room.
Browse our subwoofer amplifiers separately, or choose one of the ready-to-install packages shown below. If you are planning an in-wall audio system, contact our specialists before installation for help checking compatibility, positioning and cable requirements.
