Center Channel with Ribbon Tweeter

The Monoprice 124431 is a three-way in-wall center channel speaker designed for home theatre systems. It uses dual 5.25-inch carbon fiber drivers and a ribbon tweeter to handle dialogue and central sound effects. The cabinet mounts flush within a standard wall cavity for a discreet installation.

Suited to Dedicated Theatre Rooms

This speaker suits owners building a dedicated surround system who want the centre image locked to the screen position. The in-wall format requires cutting into drywall and running wires behind the wall, so it is not for renters or anyone unwilling to make permanent structural changes. Buyers needing a freestanding or on-wall centre should look at other form factors.

Build Integration and Amplifier Pairing

The unit fits between standard studs and connects to speaker-level outputs on an AV receiver or power amplifier. Its high-frequency attenuator offers 0, -3, or -6 dB settings to balance treble response against room acoustics. The ribbon tweeter’s wide horizontal dispersion widens the listening area across multiple seats.

Questions about this item

What amplifier power and impedance rating do I need to drive the dual 5.25-inch carbon-fiber woofers and ribbon tweeter?

Match the speaker to an amplifier rated for 8-ohm loads; choose a power output within the speaker's recommended continuous-power range so the carbon-fiber drivers and ribbon tweeter receive clean, undistorted signal.

Can I keep my existing in-wall left and right speakers and use this center channel with them?

Yes, the wide horizontal dispersion of the ribbon tweeter and the neutral voicing of the carbon-fiber drivers let the center blend with most in-wall left/right models; set the high-frequency attenuator to 0, -3, or -6 dB to match the tonal balance of the older pair.

How do I verify the ribbon tweeter is performing correctly after installation?

Play a high-resolution track with extended treble; the ribbon tweeter should render fine detail without harshness, and the sweet spot should remain wide as you move side-to-side while vertical imaging stays focused.
