The MP Multipurpose group of in-wall loudspeakers offers speakers designed for utility and flexibility. These are quality general purpose speakers. They function well as primary speakers in bedrooms, dens or living rooms; as main or surround speakers in home theaters; or in large arrays in commercial applications. Their superb value makes them perfect for a wide variety of applications. Talc-Filled Polypropylene Woofer With Treated Foam Rubber Surround And Custom Debris Screens The Niles MP Multipurpose series of loudspeakers employ a woofer made of vacuum formed polypropylene with talc added forstiffening. The resulting cone offers high efficiency which offers an easy load to amplifiers. Custom debris screens prevent insulation from coming in contact with the woofer. 34 Kaladex® Tweeter Housed In A Precision Adjustment Mechanism The MP Multipurpose series Kaladex® tweeter employs DuPont’s latest material technology to produce a dome tweeter with exceptional frequency response and low distortion. Highs are crystal clear and extended without the harshness often associated with polycarbonate designs. The Kaladex® tweeter is housed in a precision adjustment mechanism which permits the tweeter to be accurately positioned after installation for optimum performance without the diffraction distortion endemic to other speaker brands utilizing traditional pivoting tweeters. Antiresonant Wave Bracing The MP speaker’s baffle design employs specially molded ribs that increase the rigidity of the baffle and raise the resonant frequency so that less “out-of-phase” cancellation takes place. Equally important, the ribs are curved and crossed to further shift vibration modes away from low-bass canceling frequencies. This keeps bass tones rich and dynamic. Snap-In Baffle Assembly This proprietary Niles design enables installers to attach Niles loudspeaker assemblies to installed frames without additional hardware or tools. Niles snap-in design makes it easy to upgrade Niles speakers after installation without the hassles associated with removal and re-installation of traditional designs. Snap-in baffles make installation of Niles speakers baffles easier and faster than other in-wall brands. No-Strip Speaker Terminal Niles’ patented No-Strip terminal enables speakers to be connected without stripping the speaker wire. No-Strip terminals eliminate fumbling with wire strippers and input terminals. They are color coded and simply plug into the crossover circuit boards on the back of Niles speakers,resulting in positive in-phase connectionsevery time. BumpBack™ Woofer Magnet Niles engineers have utilized a unique motor construction enabling far greater “throw” or voice coil excursion. This allows a high level of bass performance to be achieved. Absolutely Flush To The Wall Appearance The unique mounting system of the MP loudspeakers powerfully clamps the frame to the bracket, sandwiching the wall material between them. Because the clamping action is totally uniform around the frame, there are no shadows or gaps between the wall and the frame. Additionally, the Niles mounting system is carefully optimized to stiffen the surrounding drywall and prevent it from resonating. You hear only the music, not the drywall. Easy Retrofit Installation In Your Existing Home Designed for ease of installation, the Niles mounting system makes retrofit installations simple and fast. A supplied template assures fast and accurate hole cutting. The bracket slips behind the drywall and the screws secure the bracket to the frame, sandwiching the drywall between them. The speaker baffle attaches to the frame, and the grille mounts over the speaker. Three Stage Installation System For Remodels Or New Construction You install only the parts you need for a particular stage of construction. When the framing and wiring are finished, you install the bracket. After the drywall is up, but before the painter begins to paint, you install the frame and provide the rustproof aluminum grilles to the painter so that they can be painted to match the surroundings. Only when construction is completely finished do you put the valuable speaker in the wall. You don’t have to mask or prep the speaker for painting, and worries about theft during the final phases of construction are never an issue! Low Diffraction, MicroPerf™ Aluminum Grilles MP speakers include aluminum grilles. The painted aluminum grille has hundreds of precisely sized perforations, creating an acoustically transparent grille. Infrared Sensor Mount The speaker baffle has a locator designed for the Niles MS-1 MicroSensor™, a miniature infrared sensor. The MS-1 installs discreetly behind the aluminum grille and therefore minimizes wall clutter in your home. When you want to control your equipment, you simply point your remote control at the speaker from up to 15 feet away.
