OSD ACE800 8" Trimless In-Ceiling Speakers (Pair)
The OSD Audio ACE800 8-Inch 2-Way Trimless In-Ceiling Speakers (Pair) bring fuller, room-filling sound and deeper bass authority to great rooms, living areas, open floor plans, and home theaters. Built with an 8-inch polypropylene cone woofer featuring long-lasting butyl rubber surrounds and a 1-inch pivoting PEI dome tweeter, the ACE800 delivers rich dynamics across 40Hz to 20kHz with 120W power handling and 87dB sensitivity. Equipped with spring-loaded binding posts, built-in dog-ear brackets, and an ultra-thin spray-paintable magnetic micro-flange grille, this architectural pair disappears flush into ceilings without sacrificing low-end impact.
If you want to know how 8-inch ceiling speakers deliver fuller bass across open-concept living rooms without bulky speaker boxes, how a 1-inch pivoting PEI dome tweeter aims crisp highs toward your seating position, or how butyl rubber surrounds outlast foam by decades, the OSD ACE800 provides the ideal balance of power and modern style. Audio installers and home cinema designers seeking 120W power handling, 8-ohm amplifier compatibility, and a 10-year warranty will appreciate the proven reliability of this ACE Series pair.

Bigger Sound for Bigger Rooms
An 8-inch woofer brings fuller bass to great rooms, living rooms, and open floor plans. Use the ACE800 pair for whole-house music, TV sound, or home theater surround channels without floor-standing speaker boxes crowding the room.
Two-Way Design with Pivoting PEI Tweeter
An 8-inch polypropylene woofer handles lows and mids, while the 1-inch pivoting PEI dome tweeter aims crisp highs directly toward your seat. Frequency response spans 40Hz to 20kHz with 87dB sensitivity and 120W power handling for clean, balanced reproduction.
Long-Lasting Butyl Rubber Surrounds
Butyl rubber surrounds provide the woofer with deeper excursion and a wider frequency response than foam surrounds, lasting far longer so the speakers keep sounding right year after year. The 8-ohm load works seamlessly with standard AV receivers and multi-zone amplifiers.
Trimless Magnetic Grilles & Simple Installation
The micro-flange grille is held on by strong neodymium magnets and sits close to the ceiling for a clean, flush appearance with no visible trim ring. Spring-loaded binding posts and built-in dog-ear brackets make installation quick: simply cut a 9.37-inch hole, wire, and tighten front screws.
