Description

The OSD Audio ACE640 is the trimless version of our popular ICE640 in-ceiling speaker. This 6.5" high-definition pair delivers smooth, detailed music with solid bass, and it disappears into the ceiling - a strong choice for whole-house music, TV sound and home theater surrounds.

  • HIGH-DEFINITION CEILING SOUND: The trimless version of OSD's popular ICE640 delivers smooth, detailed music with solid 6.5" bass. Use the pair for whole-house music, TV sound or home theater surrounds without speaker boxes in the room.
  • FIBERGLASS WOOFER, PIVOTING TITANIUM TWEETER: A 6.5" fiberglass cone stays stiff for clean bass and mids, while the 1" pivoting titanium dome tweeter aims highs toward your seat. 40Hz - 20kHz, 89 dB sensitivity, 150W handling.
  • SECURE CONNECTIONS: Gold-plated 5-way binding posts accept bare wire, pins, spades or banana plugs for a solid, corrosion-resistant connection that holds up in a permanent install.
  • TRIMLESS MAGNETIC GRILLS: The micro-flange grill is held on by strong magnets and sits close to the ceiling for a clean, flush finish. Spray paint the grills to match the ceiling so the speakers blend in with recessed lighting.
  • EASY INSTALL, SOLD AS A PAIR: The dog-leg mounting system is built into the frame, so no extra brackets are needed - tighten the front screws to lock each speaker in. Includes two passive 8-ohm speakers and two grills. 7.80" cutout.
  • WARRANTY: Backed by OSD Audio's 10-year warranty.

Each speaker uses a 6.5" fiberglass cone woofer and a 1" pivoting titanium dome tweeter. Fiberglass is light and stiff, so the woofer stays clean and controlled as the volume goes up. The pivoting tweeter can be aimed toward the listening area, so you get clear highs even when the speaker cannot sit directly above your seat.

Frequency response is 40Hz - 20kHz, sensitivity is 89 dB and power handling is rated at 150W. At 8 ohms, the ACE640 works with standard stereo amplifiers, AV receivers and multi-zone systems.

Gold-plated 5-way binding posts give a secure, corrosion-resistant connection and accept bare wire, pins, spades or banana plugs. The trimless micro-flange grill is held on by strong magnets and sits close to the ceiling. Grills are spray paintable to match any room.

Installation is quick: the dog-leg mounting system is built into the frame, so no special brackets are needed. Cut a 7.80" hole, wire the speaker, set it in place and tighten the front screws. Each speaker measures 8.86" in diameter with 3.54" of mounting depth.

Sold as a pair with two spray-paintable magnetic grills. Passive speakers - an amplifier or receiver is required. Backed by OSD Audio's 10-year warranty.

What's on your mind?

Anthony Wise • 04/05/2020, 10:07:11 AM I am looking to add stereo speakers to each of my basement rooms. They are about 15-20 ft square. I have three rooms. Would these suffice or should I get the 8" versions? I plan on also purchasing another AMP200 to drive these sets of speakers via two volume controls (from the zone 2 of my media room receiver).
Customer Service • 04/06/2020, 1:27:03 PM
Hi Tony: Either speaker will work and both are in stock. The 8" will buy you a little more Bass, they go down to 35 Hz versus 40 Hz of the ACE 640. Power handling is the same. Make sure you purchase the SVC300 for your application. Speaker Placement should be 8 feet apart 3.5' from the 10 foot wall and roughly 5' from the 15 foot wall. 1 pair of speakers will be wired from the the first SVC300 (connected to Speaker A of the AMP200) and another pair of speakers wired from the second SVC300 (connected to the Speaker B) That would take care of two rooms. I am sure you have determined which two pair of speakers will connect to a single SVC300. You can either split the signal after the Volume Control or connect the second pair of speakers to the first pair combining the Input cable from the Volume Control to the cable that will be connected to the second pair of speakers. So the first pair of speakers will have two cables terminated to each input connector (L & R +/-). Make sure you set the Impedance Matching switch to 1/2X. That will get the most output from your AMP200 (connected to your ZONE2 output). TimL/ 03-6-2020
Matt • 11/05/2022, 10:27:49 AM Do you sell speaker back boxes that will fit these?
Customer Service • 12/08/2022, 3:26:47 PM
Hi Matt: We have a metal back box, the BK-BB6. It is for new construction where the walls are open. The Box opening is 7.75". The cutout dimension of the ACE640 speaker is 7.80". The boxes sell for $49.99 each. All of our In-Ceiling and In-Wall speakers feature infinite baffles so they can work without a back box.
