Four-Speaker High-Definition Audio Bundle
This 2-pair bundle includes four matching high-definition ACE640 speakers, making it the perfect packaged solution for powering two distinct audio zones or outfitting a complete 5.1.4 or 7.1.4 Dolby Atmos ceiling speaker layout.
Woven Fiberglass Woofers & Pivoting Titanium Tweeters
Each speaker utilizes a rigid 6.5-inch woven fiberglass cone woofer that remains stiff and distortion-free as volume increases. The 1-inch pivoting titanium dome tweeter can be independently aimed toward primary seating areas, delivering crystalline dialogue and pinpoint sound effects.
Flush Architectural Trimless Micro-Flange Grilles
OSD Audio's trimless design eliminates bulky frames. Four spray-paintable magnetic grilles snap securely onto the baffles, blending seamlessly into drywall ceilings alongside modern recessed lighting.
Secure 5-Way Binding Posts & Easy Installation
Gold-plated 5-way binding posts accept bare speaker wire, pins, spades, or banana plugs for permanent corrosion resistance. The built-in dog-leg mounting system secures each speaker into a 7.80-inch ceiling cutout with standard screwdriver turns.
