Get real Dolby Atmos overhead sound without cutting a single hole. Set the T55E pair on top of the speakers you already own - the angled baffle bounces the height channel off your ceiling and back down over the couch. Or mount them on the wall with the brackets already built into the back panel. 5.25" carbon fiber woofer, 1" silk dome tweeter, sealed cabinet, sold as a pair.

• ADD ATMOS HEIGHT CHANNELS WITHOUT CUTTING YOUR CEILING: Set the pair on top of your front or rear speakers and the angled baffle bounces the height channel off the ceiling. You get 5.1.2 overhead sound with two screws’ worth of work and no holes in the drywall.
• DROP-IN UPGRADE FOR ANY ATMOS RECEIVER: Wire them to the height or surround outputs on the back of your AV receiver and assign the channel in its setup menu. Works with any Dolby Atmos or DTS:X receiver that drives a 4-ohm load.
• MOUNTS ON THE WALL WHEN YOU NEED IT TO: Keyhole brackets are built into the back panel, so the same pair goes on the wall as height or surround speakers. No bracket kit to buy.
• CARBON FIBER WOOFER, SILK DOME TWEETER: A 5.25" carbon fiber cone and a full 1" silk soft dome — the drivers you would expect a size class up, in a box that fits on top of a tower speaker.
• SEALED CABINET, 107 dB MAX SPL: The sealed MDF enclosure keeps bass tight instead of boomy, and 25–100 W of power handling means the height channel keeps up when the movie gets loud.
• ALSO WORKS AS A STEREO PAIR: Add a subwoofer and the same speakers run as compact stereo monitors for music. Two jobs, one purchase.

Want overhead Dolby Atmos sound without cutting into your ceiling? The OSD Black T55E is the pair that gets you there. Each speaker has an angled top baffle: set it on your existing floorstanding or bookshelf speaker, and it fires the Atmos height channel up into the ceiling, which reflects it back down over your seats. One pair builds a 5.1.2 system. Two pairs build 5.1.4.

Inside each cabinet is a 5.25" carbon fiber woofer and a 1" silk soft dome tweeter, crossed over at 2.8 kHz in a sealed MDF box. Rated 100–20,000 Hz (−3 dB), 89 dB sensitivity (2.83 V / 1 m), 4 ohms, 25–100 W, 107 dB max SPL.

Not putting them on top of a speaker? Keyhole brackets are already built into the back panel — mount them on the wall as height or surround channels, tweeter down, 4–6 ft up. Or add a subwoofer and run the pair as stereo monitors for music.

Hooking them up takes five minutes: power the receiver off, run speaker wire to the binding posts, keep red to red and black to black, then assign the channel in your receiver menu and run its auto-calibration. Check that your receiver handles a 4-ohm load first — most mid-range and better models do.
