Essential Info

The High Definition (HD) series of in-wall / In-ceiling Loudspeakers were specifically designed for superior sonic quality. They employ advanced technology components made to extract the subtle audio in recorded music or the action in a movie. They are the ideal choice for any home theater where the quality of sound is the most important consideration.

About the Woofer
The Niles Audio HD speakers have a woofer that features an injection-molded TCC (Talc, Carbon, and Ceramic-filled) polypropylene cone that is extremely stiff and lightweight, which helps reduce breakup and lowers distortion while delivering an accurate, dynamic response. A butyl rubber cone surround dampens midrange resonance and provides exceptional durability. A vented pole piece adds powerful bass response. A bumpback woofer magnet allows a high level of bass performance to be achieved.

About the Tweeter
The Niles Audio HD speakers have a Teteron tweeter with a tri-laminate design that eliminates unwanted resonances and prevents breakup modes, leaving an ultra-clear, sweet, natural sound which still maintains ultra-wide dispersion for clear and detailed high-frequencies. The tweeter is features precision adjustment control which moves in 1mm increments, then pivots for precise aiming of high frequencies. This can be done post-installation so you can direct sound in the ideal listening area.

Additional Features
Anti-resonant wave bracing raises the resonant frequency so that less "out-of-phase" cancellation takes place, and shifts vibration modes away from low-bass canceling frequencies keeping bass tones rich and dynamic. Front mounted bass and treble controls allow for instant fine tuning after the speakers are installed. Installation uses a snap-in baffle assembly which powerfully clamps the speaker frame to the bracket (sold separately) leaving an absolutely flush to the wall appearance; this works for both new construction and retrofit applications. The aluminum grille has hundreds of precisely sized perforations, creating an acoustically transparent installation. The speaker even has a a knock-out for an infrared (IR) sensor (Niles Audio MS110 - sold separately) installs discreetly behind the aluminum grille, when you want to control your equipment, you simply point your remote control at the speaker.

Please Note: High Definition (HD) Series speakers from Niles Audio are designed for an in-wall (wall mount) installation as their primary application, but can be used for an in-ceiling (ceiling mount) application as well.
