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.

FeaturesRibbon Tweeter: A ribbon tweeter requires about 90 Percent less excursion than a typical 1in dome tweeter, making it capable of very high acceleration, which means that it is very responsive to musical nuances with less distortion. Ribbon tweeters have a wide horizontal dispersion and a very tight vertical dispersion, thereby increasing the size of the audio insweet spotin.

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.
