OSD ACE840TT 8" Trimless Dual Tweeter Stereo In-Ceiling Speaker (Single)
The OSD Audio ACE840TT 8-Inch Stereo DVC Trimless In-Ceiling Speaker (Single) delivers expansive, full-bodied two-channel stereo sound reproduction from a single ceiling opening, providing significantly more bass authority and room coverage than 6.5-inch single-point models. Engineered with an 8-inch woven fiberglass cone woofer featuring dual voice coils (DVC) and dual independent 1/2-inch titanium-coated dome tweeters, the ACE840TT handles 120W across 38Hz to 20kHz with 88dB sensitivity. Equipped with separate spring-loaded binding posts for left and right channels and an ultra-thin magnetic spray-paintable grille, this single-point stereo speaker is the ideal architectural audio solution for master baths, large walk-in closets, kitchens, and offices where installing two speakers is impractical.
If you want to know how an 8-inch dual voice coil woofer delivers deep 38Hz bass while playing both left and right stereo audio channels, how dual titanium tweeters disperse true stereo sound from one ceiling cutout, or why moisture-resistant fiberglass cones excel in steam-prone bathrooms, the OSD ACE840TT provides the premier solution. Custom integrators and homeowners searching for 120W power handling, 9.37-inch cutout dimensions, and a 10-year warranty will appreciate the space-saving performance of the ACE840TT.

Two-Channel Stereo from One 8-Inch Ceiling Opening
The dual voice coil woofer plays both left and right channels through a single 8-inch cone, delivering rich two-channel stereo separation where only one speaker fits—in half the ceiling space of a standard pair. Ideal for larger single-speaker zones like master bathrooms, expansive walk-in dressing rooms, and open kitchens.
Deep 38Hz Bass with Woven Fiberglass Cone
The substantial 8-inch woven fiberglass cone moves significantly more air and covers larger room dimensions than 6.5-inch single-point models, delivering impactful bass down to 38Hz. The lightweight, stiff fiberglass structure resists humidity and cone deformation over decades of use.
Dual Independent Titanium-Coated Dome Tweeters
Dual 1/2-inch titanium-coated dome tweeters handle high frequencies for each stereo channel independently, projecting smooth, balanced detail across the entire room up to 20kHz without acoustic interference.
Trimless Magnetic Grille & Simple Installation
The micro-flange grille is held by strong neodymium magnets for a clean, flush appearance with minimal visual impact. Grilles can be spray-painted to match ceiling paint. Spring-loaded binding posts accommodate left and right speaker leads directly, while dog-ear brackets lock into a 9.37-inch cutout.
