Kevlar Woofer for Deep, Clean Bass
The sturdy 8-inch Kevlar cone keeps its shape even at very high energy levels, so you can turn the volume up without acoustic distortion. It produces deep, rich bass down to 35Hz, making it an excellent choice for large living spaces, media rooms, and home theaters.
Aimable 1-Inch Aluminum Dome Tweeter
The 1-inch aluminum dome tweeter pivots smoothly, allowing you to aim high frequencies directly toward the listening area for clearer, more detailed highs from anywhere in the ceiling. Sophisticated crossover networks blend the drivers smoothly.
High 175W Power Handling & Secure Connections
Each speaker handles 175W, ensuring the pair stays composed and dynamic at elevated movie and music playback volumes. The 8-ohm load works with standard stereo amplifiers and AV receivers. Gold-plated 5-way binding posts give a secure, corrosion-resistant connection.
Trimless Paintable Grilles & Easy Installation
Magnetic micro-flange grilles go on in seconds and sit close to the ceiling for minimal visual impact. Grilles can be spray-painted to match any room decor. Four built-in dog-ear brackets lock firmly against drywall into a 9.37-inch cutout.
