Does it fit the on the 6 CCM 662 Bowers Wilkins in-ceiling speaker with a 202mm (7.95 hole cutout on the ceiling?
1 Answer
Hi Bernard: The back box cutout is only 7.75" or 196mm so will not work with the B&W 662 which closer to 8.0" 202mm. We also have a Backbox for 8.0" with 9.5" or 241.3mm Sorry about that TL/5029

Will this work with the trimless series of speakers?
1 Answer
Hi Matt, Typically any 6.5" speaker will fit, but just compare the cutout diameter of the speaker to the hole diameter of the box.

I am looking for a round back box to fit the 6.5 or 8in speaker. Do you make one?
1 Answer
Hi Mark, We do not make a universal back box but offer a rectangular back box that fits between the ceiling joists that was created to be used with a couple different models of our In-ceiling speakers. We do offer speakers double duty as 8-ohm residential speakers or 70V commercial speakers. Check out the ICE620ST or ICE800ST which feature round back boxes. These are sold as each. TL/MA - 1561

I am looking for the same style enclosure or in top hat design for 6.5" speaker but for outdoor,water use it will be exposed. Have you seen or make anything similar that is sealed or maybe out of plastic or pvc?
1 Answer
Hi Jim, We do feature commercial-grade speakers with back-box enclosures; however, these models are not classified as weather-resistant. We offer rock, patio and garden speakers that are weather resistant; however, it sounds like you already have the speaker and are trying to find a proper enclosure for your application. Sorry I could not be more helpful. TL/MA

What's the best way to install this box on sheet rock ceiling board?
1 Answer
The box is meant to either mount to the Ceiling joist or to be suspended from the ceiling when dealing with a drop down ceiling. it sounds like you will be mounting the sheetrock to the joists so... The box frame is 17 3/4" by 18" with the actual box meant to fit between two standard ceiling joists with the flange either screwed or nailed directly into the bottom of the Joist. Their is also a lip on the box which helps when cutting out the ceiling tile. Plus, once the box is secure it will help support the weight of the speaker as well. Note: You can also increase the effectivess of the box by adding a fiber fill... A significant increase in the effective volume of a sealed-box loudspeaker can be achieved by a filling of fibrous material, typically fiberglass, bonded acetate fiber (BAF) or long-fiber wool.
