Overview

The Monoprice 134199 Carbon Fiber In-Wall Speakers are a pair of 3-way speakers engineered to deliver high-fidelity audio while virtually disappearing into your living space. Each speaker houses a 6.5-inch carbon fiber woofer with a rubber surround, a 3.5-inch carbon fiber mid-range driver, and a 1-inch silk dome tweeter. Carbon fiber as a cone material offers a compelling combination of low mass and high rigidity, meaning the drivers respond more efficiently to power input while resisting the flexing that causes distortion in softer materials. The result is cleaner bass reproduction, more articulate mids, and higher power handling than comparably sized speakers using polypropylene or paper cones.

The frequency response spans from 58Hz to 20kHz, covering the vast majority of musical and cinematic content, though bass enthusiasts will likely want to pair these with a subwoofer for the lowest octaves. A built-in high frequency attenuator gives you control over the tweeter's output, allowing you to tame brightness in reflective rooms or boost detail in spaces with heavy soft furnishings. Installation has been designed for accessibility: a paper cutout template guides your wall opening, and spring-loaded mounting tabs secure each speaker with just a screwdriver. The paintable magnetic grille attaches without visible hardware, letting you match your wall color for a seamless finish. With 160 watts of maximum input power per speaker, these are well-suited for dedicated listening rooms, home theaters, and whole-home audio systems where clean sound and minimal visual footprint are priorities.

Key Features

Sound Quality: Life is too short for speakers that don't sound great! We believe that the whole point of listening to music is to hear it as the artist intended. Our engineers and audio experts have spent countless hours listening to and comparing various speakers until we were satisfied we had found models that fit our demanding standards.

Style: While Monoprice believes in function over form, there is nothing wrong with having speakers that look good, too. This in-wall speaker helps reduce clutter by getting your speakers off the floor or bookshelves. The magnetic metal grille can be painted to match your ceiling, so it virtually disappears from view.

Simplicity: Installation is as easy as it can get. Use the included cutout template to mark your wall, make the cut then, using only a screwdriver, secure the speaker to the wall with the easy install mounting tabs.

Carbon fiber woofers are lighter and stiffer than conventional materials used in speaker manufacturing. The speaker cone is more sensitive to power, which means that you get more volume using less power. Additionally, the stiffer material means deeper bass and higher power handling, with significantly less distortion.

Pros & Cons

👍 Pros

  • Carbon fiber woofer and mid-range drivers are lighter and stiffer than conventional materials, producing deeper bass with less distortion.
  • Three-way driver configuration provides clear separation across low, mid, and high frequencies for balanced sound.
  • Paintable magnetic grille allows the speakers to blend seamlessly into any wall or ceiling finish.
  • Built-in high frequency attenuator lets you tune treble output to match your room and preferences.
  • Simple installation with included template and screwdriver-only mounting tabs eliminates the need for special tools.

👎 Cons

  • At 160 watts maximum input power, these may not deliver enough output for very large rooms or demanding home theater setups.
  • In-wall installation requires cutting into drywall, which is permanent and not easily reversible if you change your mind.
  • The 58Hz low-end frequency response means a separate subwoofer is recommended for deep bass content.
  • Rubber surround on the woofer may degrade over many years in humid or non-climate-controlled environments.
