OSD ACE800ST 8" 70-Volt Commercial Trimless In-Ceiling Speaker (Single)
The OSD Audio ACE800ST 8-Inch 70V/25V Commercial Trimless In-Ceiling Speaker (Single) delivers full-bodied commercial sound reinforcement, deeper 35Hz low-end coverage, and exceptional speech intelligibility for large venues, hotel lobbies, auditoriums, malls, and corporate open-concept spaces. Built with an 8-inch polypropylene cone woofer with rubber surround and a 0.5-inch PEI dome tweeter, the ACE800ST handles 120W across 35Hz to 20kHz with 89dB sensitivity. Featuring a dual 70V/25V transformer dial with high-output taps (32W, 16W, 8W, 4W, or 8-ohm bypass) and an edgeless magnetic spray-paintable grille, this commercial speaker ensures even coverage and low line loss across large-scale commercial speaker networks.
If you want to know what 8-inch commercial 70V speakers provide richer low-frequency presence in high-ceiling dining rooms or retail spaces, how high-wattage 32W taps deliver clean acoustic output in busy environments, or how trimless grilles maintain upscale architectural aesthetics, the OSD ACE800ST is the benchmark choice. Commercial integrators and sound contractors seeking 120W power handling, 9.68-inch cutout dimensions, and a 10-year commercial warranty will appreciate the performance of the ACE800ST.

Fuller Commercial Audio for Large Venues
Designed for expansive commercial environments where background music needs body and paging must cut through ambient room noise. The large 8-inch polypropylene woofer moves substantial air, delivering rich 35Hz bass and full-range acoustic energy across open-ceiling retail, hotel lobbies, and sports bars.
High-Output 70V/25V Tap Settings
Equipped with a dual 70V/25V multi-tap transformer dial offering 32W, 16W, 8W, and 4W settings, plus an 8-ohm direct bypass. The 32W tap provides high sound pressure levels for loud commercial environments, while lower taps allow uniform distributed coverage across quiet corridors.
Low Loss Over Long Cable Runs
High-impedance 70V distribution carries audio signals at low current, dramatically reducing power loss and cable heating across hundreds of feet of speaker wire. This keeps commercial wiring straightforward, efficient, and cost-effective.
Trimless Magnetic Grille & Dog-Ear Brackets
The micro-flange grille attaches via neodymium magnets, eliminating visible plastic framing and sitting flush against drywall. The white steel mesh is spray-paintable to match any commercial interior. Built-in dog-ear brackets lock securely into a 9.68-inch ceiling cutout.
