The OSD Audio ACE840TT, like its younger sibling the ACE640TT, delivers smooth two-channel stereo sound from a single trimless in-ceiling speaker - in half the space of a standard speaker pair. It is made for whole-house audio in rooms that have a stereo signal but space for only one speaker.

• STEREO FROM ONE SPEAKER: The dual voice coil woofer plays both left and right channels through one cone, giving you smooth two-channel sound where only one speaker fits - in half the space of a standard pair.
• MORE BASS THAN THE 6.5" VERSION: The 8" fiberglass woofer gives more bass and covers a larger area than the ACE640TT, making it the better pick for bigger single-speaker rooms. 38Hz - 20kHz, 88 dB sensitivity, 120W.
• DUAL TITANIUM TWEETERS: Dual 1/2" titanium-coated dome tweeters handle the highs for both channels, so music sounds balanced and detailed from one spot in the ceiling.
• TRIMLESS MAGNETIC GRILL: The micro-flange grill is held on by strong magnets for quick installation and minimal visual impact. Spray paint it to match the ceiling and the speaker blends in with recessed lighting.
• SIMPLE INSTALL: Spring-loaded binding posts for left and right inputs, plus built-in dog-ear installation brackets. 9.37" cutout, 10.79" diameter, 4.02" depth. Sold as a single passive 8-ohm speaker with grill.
• WARRANTY: Backed by OSD Audio's 10-year warranty.

The ACE840TT uses an 8" fiberglass woofer, so it produces more bass and covers a larger area than the 6.5" version. Its dual voice coil (DVC) design lets the left and right channels play through one cone, and dual 1/2" titanium-coated dome tweeters handle the highs.

Use it in bathrooms, hallways, closets, laundry rooms, bedrooms and offices. Frequency response is 38Hz - 20kHz, sensitivity is 88 dB (1W/1m) and power handling is rated at 120W. Connect the left and right channels from any stereo amplifier, receiver or multi-zone system that drives 8-ohm speakers.

The trimless design uses a micro-flange grill held on by strong magnets, for quick installation and minimal visual impact. The grill is spray paintable to match any ceiling.

To install, cut a 9.37" hole, connect the left and right speaker wires to the spring-loaded binding posts, set the speaker in place and tighten the built-in dog-ear brackets. The speaker measures 10.79" in diameter with 4.02" of mounting depth.

Sold as a single speaker with a spray-paintable magnetic grill. Passive - an amplifier or receiver is required. Backed by OSD Audio's 10-year warranty.
