Alpha Ceiling Speaker Dual 5.25" Carbon Fiber Surround 2-way Vari-Angled (single) This carbon fiber in-wall speaker is the perfect combination of performance and style. The use of carbon fiber for the woofer means that the speaker can hit harder, go lower, and handle more power with significantly less distortion than conventional drivers. The silk dome tweeter produces clean, crisp, and clear highs and mids. You can fine tune the blend of sound using the built-in high frequency attenuator in case the sound is too bright. The adjustable angle feature allows you to point the speaker towards your ideal listening location, for optimal sound quality. 5.25" Carbon Fiber 2-way In-Wall Speaker with Magnetic Grille 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, and the metal grille can be painted to match your wall, 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 gives you higher sensitivity, deeper bass, and higher power handling. 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.
