Overview

The Monoprice Alpha 113684 2-Way In-Ceiling Speakers bring together carbon fiber driver technology and silk dome tweeters in a discreet, flush-mount package designed for home theater, whole-home audio, or dedicated stereo listening. The 6.5-inch carbon fiber woofer cones are stiffer and lighter than conventional materials, allowing them to move air more efficiently while keeping distortion low — the result is tighter, more impactful bass response than you might expect from an in-ceiling speaker at this price. Paired with 1-inch silk dome tweeters, the speakers produce a balanced, full-range sound signature with smooth highs and well-defined midrange detail, making them equally capable with music, movie soundtracks, and spoken dialogue.

Design-wise, the Alpha 113684 speakers prioritize a clean aesthetic. The magnetic grilles snap on and off without visible hardware, and their slim profile sits nearly flush with the ceiling surface. With no branding logos on the grille face and the option to paint them any color, these speakers can blend into virtually any room decor. Sold as a matched pair, they are ready for stereo installations or can be mixed into larger multi-speaker configurations for surround sound and distributed audio throughout the home.

Key Features

Pros & Cons

👍 Pros

  • Carbon fiber woofer cones produce deeper bass with lower distortion than conventional paper or polypropylene drivers.
  • Slim magnetic grilles are logo-free and paintable for a clean, unobtrusive ceiling installation.
  • Sold as a matched pair, simplifying purchasing for stereo or multi-channel setups.
  • Silk dome tweeters deliver smooth, detailed highs without harshness.
  • Versatile enough for whole-home audio, stereo listening, or home theater surround duty.

👎 Cons

  • In-ceiling installation requires cutting holes in your ceiling drywall, which may not be reversible.
  • No built-in amplification, so a separate amplifier or AV receiver is required to drive them.
  • Fixed mounting position means you cannot adjust speaker angle or aim after installation.
  • 6.5-inch woofers may not deliver enough low-end output for larger rooms without a dedicated subwoofer.
