Kevlar Woofer for Clean, Deep Bass
Kevlar is one of the premier materials for loudspeaker woofer cones. The sturdy 6.5-inch Kevlar cone holds its shape even at high volumes, responding note for note without coloration. Turn the system up for movies and parties, and the bass remains tight, rich, and articulate down to 45Hz.
Aimable 1-Inch Pivoting Aluminum Dome Tweeter
The 1-inch aluminum dome tweeter pivots smoothly on its gimbal, allowing you to aim high frequencies directly toward the primary seating area even when the speaker cannot be positioned directly overhead. Sophisticated crossover components blend the drivers seamlessly.
Secure Connections & Standard Amplification
Gold-plated 5-way binding posts accept bare speaker wire, pins, spade connectors, or banana plugs for a solid, corrosion-resistant connection. Each speaker handles 90W RMS (180W peak) and presents an 8-ohm load compatible with standard stereo amplifiers, AV receivers, and multi-zone systems.
Trimless Magnetic Grille & Built-In Dog-Ear Brackets
The trimless Architectural Ceiling Element (ACE) design features an ultra-thin micro-flange grille secured by strong neodymium magnets for a clean, flush appearance. Grilles can be spray-painted to match ceiling finishes. Installation requires a 7.80-inch cutout with built-in dog-ear brackets locking firmly from the front.
