Overview

The Monoprice Alpha Series 134200 in-wall speakers are a 3-way design built around an 8-inch carbon fiber woofer with rubber surround, a 3.5-inch carbon fiber midrange driver, and a 1-inch silk dome tweeter. This dedicated driver arrangement allows each component to focus on its optimal frequency range, resulting in clear highs, articulate mids, and full bass response down to 45Hz. The carbon fiber cone material is both lightweight and rigid, reducing distortion and breakup at higher volumes compared to traditional paper or polypropylene cones. A built-in high frequency attenuator gives you control over treble output, letting you fine-tune the sound for your specific room without external processing.

Designed for permanent in-wall installation, these speakers disappear into your living space both visually and physically. The paintable magnetic grilles snap on and off easily for access while allowing you to match any wall color for a truly invisible audio setup. Rated at 200 watts maximum input and 8 ohms impedance, they pair well with most home theater receivers and stereo amplifiers. Sold as a matched pair, they offer a cost-effective path to high-quality architectural audio for home theater front or surround channels, stereo listening rooms, or whole-home distributed audio systems.

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

  • 8-inch carbon fiber woofer produces deep, controlled bass down to 45Hz without a subwoofer for many listening scenarios
  • 3-way design with dedicated midrange driver ensures clear vocal reproduction and detailed sound across the frequency range
  • Paintable magnetic grilles allow completely invisible installation that blends with any interior
  • Built-in high frequency attenuator provides room-specific tuning without needing an external equalizer
  • Sold as a pair, reducing cost compared to buying individual in-wall speakers

👎 Cons

  • In-wall installation requires cutting into drywall, making placement permanent and not easily repositioned
  • No built-in mounting hardware for retrofit ceiling installation, strictly wall-mount design
  • 200 watts maximum input power may be limiting for very large rooms or high-output home theater setups
  • 8-ohm impedance means they cannot be easily daisy-chained in parallel on most standard amplifiers
  • Bass response starting at 45Hz may still benefit from a subwoofer for home theater low-frequency effects

Frequently Asked Questions

Yes, the Monoprice 134200 comes as a pair of in-wall speakers, each with its own paintable magnetic grille.
Yes, the magnetic grilles are specifically designed to be paintable, allowing you to blend the speakers into any room's décor.
The HF attenuator lets you adjust the tweeter output level to suit your room's acoustics, reducing harshness in reflective rooms or boosting treble clarity in softer environments.
They require a cutout sized for an 8-inch in-wall speaker. Check the manufacturer's template specifications for exact dimensions before cutting.
They handle up to 200 watts maximum input power at 8 ohms impedance, so a standard home theater receiver or amplifier rated for 8-ohm speakers will drive them well.
