I've purchased the CW640SQ speakers but the spacing of my studs is too narrow for the LCR. What do you recommend for the center channel?
1 Answers
Hi Pennie: We do not have a dedicated center channel speaker to match the CW 640 SQ speaker. I was checking to see if we had a CW 840 SQ that would work. But otherwise the only LCR speaker we have is the MK IW 550 which does fit between the studs but does not have proper timbre match to your CW 640 SQ which feature a mineral filled poly woofer and Silk Soft Dome Tweeter. The MK IW 550 is a Carbon Fiber woofer and Metal dome tweeter. We also recommend going to the ceiling with angled LCR speakers like our ACE870 speakers for the fronts and ACE-670 LCR speakers for all effects/surround speakers. Note these are also a trim-less design If you had access to another CW-640 SQ or even the 8" to match with the 2 CW 640 SQ you have. Amazon may have cleaned us out. TL/4320

Are the grills paintable?

Hi Rob: Yes they are, Spray paint seems to work the best. Also remove cloth from inside of the speaker grill. TL/4046

March 1, 2016
The main page on the site for the OSD-CW-640 SQ says the overall dimension is 8 5/8" H x 8 5/8" W x 3 1/4" D. The manual stated that the overall dimension is 7 3/8" H x 7 3/8" W x 3 1/4" (Same as the cutout dimension). Can someone verify the true outside dimensions with the grille attached? Thanks!
1 Answers
Hi Phil: Sorry for the confusion, apparently the IW-640 SQ and IW-540 SQ both list the cut out and outer dimensions the same. Will work to correct that... Outside dimensions are 8 5/8" x 8 5/8" The Cutout dimensions are: 7 3/8" x 7 3/8" Verified. Thank you for bringing this to our attention TL/3731

Do you recommend these for LCR, especially the center channel? I am currently using a pair as rear/surrounds. This is for day-to-day use in family room and not a dedicated home theater. Can I buy single for center or pairs only?
1 Answers
Hello, This isn't typically used as an LCR but it could be used as a center channel. They are only sold in pairs however. I would personally recommend something like our IW545 or MK-IW550 for an in-wall center speaker. BM 2648

What is the difference between this speaker and IW680, aside from form factor? Can I expect the same performance from each? Thanks!
1 Answers
Hi Drumm1n: Same Woofer Cone size and material, identical pivoting 1" soft dome tweeter. identical specs Frequency response, Sensitivity and Power Handling all the same. The frame is 8/34" square for the CW-640 SQ versus 12" x 8 5/8" for the IW-680. Which works better for you application and the Square pair are less money as well. TS-2267

Great speaker, Great value
The CW640SQ speaker is a quality built and designed ceiling speaker. I mounted them in the ceiling and they are used as rear surrounds. The frequency response is very broad and captures the sound well. The tweeter pivots so aiming them is simple. The push in connectors make hooking up the wires easy. Mounting is a breeze using the "dogleg" frame mounted method..Just a turn of the screw and they clamp tight to the drywall. The grill and frame are paintable. Included is a template to mark the cutout and can also be used for painting the frame. Its best to remove the paper overlay on the grill prior to painting by soaking in warm water. I would recommend these to anyone who wants the most out of their money and ease of installation.
ProsGreat value. Easy install. Square shape.
Best UsesCeiling/wall mount. Front/rear surrounds.

Clear and Powerful Sound. Price is just a bonus.
Super fast processing & shipping, easy installation. I replaced my JBL on-wall surrounds in the family room (20x19x9H) open to kitchen. WOW! what a difference, these dominate the fronts. Hence, I am replacing the LCRs with these. Wish I can buy single speaker for center, but at this incredibly low price, I shouldn't complain. I will use all OSD speakers for my (& my friend's) dedicated home theater project and suggest you all the same.
ProsStyle, Quality (build & sound), PRICE!

Excellent performance for the money
OSD is the only place where I found a speaker size that would fit into existing cut outs. They were a huge step up from the original speakers. I like the adjustable cone angle feature.

I use these speakers in the back wall of tv room for surround sound. They are easy to install but I do suggest watching the instructional video for installation hints. The sound is good for the price.
