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-ceiling 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 ceiling, make the cut then, using only a screwdriver, secure the speaker to the ceiling 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 woofers are lighter and stiffer than conventional materials, enhancing sensitivity to power.
  • The stiffer carbon fiber material contributes to deeper bass and higher power handling.
  • Offers significantly less distortion due to the properties of the carbon fiber woofer material.
  • Provides more volume using less power, thanks to the speaker cone's increased sensitivity.
  • Equipped with a 1in silk dome tweeter, typically associated with smooth and clear high-frequency reproduction.
  • Features a wide frequency response range of 45Hz ~ 20kHz, capturing a broad spectrum of audio.
  • Includes a built-in high frequency attenuator, allowing for sound customization to suit room acoustics.
  • Designed with a paintable magnetic grille, enabling it to virtually disappear from view when matched to ceiling color.
  • Installation is simple using the included cutout template and easy-install mounting tabs, requiring only a screwdriver.
  • Helps reduce clutter by integrating speakers directly into the ceiling.
  • Maximum input power of 160 watts allows for robust audio performance.

👎 Cons

  • Requires professional installation into a ceiling, which may involve cutting and wiring.
  • The frequency response starts at 45Hz, which might not produce the absolute deepest sub-bass without a dedicated subwoofer.
  • While the grille is paintable, ensuring a perfect match to ceiling paint can be challenging.
  • The speakers are in-ceiling, meaning they are fixed in position and cannot be easily repositioned for sound staging.
  • The magnetic grille, while convenient, might be susceptible to accidental dislodgement if not properly seated or in high-vibration environments.
  • Specific details on crossover points or sensitivity are not provided, which could be important for advanced system matching.
