Alpha Series 10-Inch In-Wall Subwoofer

The Monoprice 130487 Alpha Series subwoofer is a new 10-inch in-wall speaker designed for home theater bass. It uses a carbon fiber driver that stays rigid under heavy stress, reducing distortion from cone flex. Rated at 300 watts peak power, it targets listeners who want deep, room-filling low frequencies without floor-standing cabinets.

Build Integration

This in-wall unit mounts directly into a stud bay using included easy-install tabs and a cutout template, requiring only a screwdriver. It frees up floor space and eliminates the need for a separate subwoofer enclosure in the room. The removable grille accepts paint so the speaker blends into the wall finish. An external amplifier such as the Unity series 200-watt bridgeable power amp is required to drive the passive subwoofer.

Sustained Output Behaviour

The carbon fiber cone material resists deformation during prolonged high-excursion passages, keeping distortion low when the driver is pushed hard. Its stiffness helps maintain consistent bass extension during long movie scenes or music sessions rather than softening as the cone heats up. The 300-watt peak rating indicates the thermal and mechanical limits for dynamic bursts, not continuous sine-wave output.

Questions about this item

How deep does the 300 watt peak power handle sustained bass before the driver reaches its limit?

The carbon fiber cone maintains shape under heavy stress, giving high volume bass extension with minimal distortion during extended playback.

What heat or noise does the in-wall sub produce when running all day?

Passive design means no internal amplifier heat or fan noise; only the driver moves, so the wall cavity stays quiet and cool.

Which amplifier must I already own to power this 10 inch subwoofer?

A separate power amplifier is required; the manufacturer suggests the Unity series 200 watt bridgeable power amp for proper operation.
