BB6 Back Box 6.5" Ceiling Speaker Fire Retardant

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.

Hi Christian, The CW540SQ actual

HI Mark, The dimensions are as follows: 17 3/4" x 18" x 5" The box itself measures 13 1/4" x 16 3/4" at the base and 12.5" x 16" at the top. It was designed to fit between two ceiling joists 16" apart on center and 6" deep. It also feature a loop on the top in case it needs to be secured by a wire in a drop down ceiling. The opening hole for the 6" speaker is 8 1/4" and and has a flange that is 3/8". TL/MA - 1562

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

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

Hi Reed, Yes this would go before the sheet rock in for pre-construction. CL

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.
