The 2-way in-ceiling speaker uses a 6.5" white polypropylene woofer resulting in a more polished high frequency roll-off, reduced beaming and exceeding mid frequencies. A 1" silk dome swivel tweeter delivers a smoother and warmer sound experience. The high-grade crossover utilizes oxygen-free copper inductors, high watt ceramic resistors and audiophile capacitors. Speaker equalization adjustments make precision tuning effortless. All Ghost Seriesâ„¢ speakers come with a patented 2-millimeter reveal magnetic frameless grill. The rimless grill attaches easily and covers the lip. Once installed, no part of the speaker shows except for the grill, making the speaker disappear into the installation environment. Making the speaker a true labor and time saver.
