## Questions & Answers

**Q: I'm a little conflicted with the dimensions? Listing states - 9.31 inches x 9.8 inches x 14.81 inches. I have standard 2x4 studs 16's on center.**
A: William, The actual hole that you make in the wall for the 255C-RT is 13 1/8" x 7 5/8".  The dimension you listed is the overall face frame outside the wall cavity.  You should have no problem with your 16" o/c studs.  I have this speaker and like it very much.  Each to install and setup.  Good luck!

**Q: The specs say it is almost 10" deep but answers say it fits in a "regular" stud wall. My wall is a standard depth based on 2x4s.will it fit?**
A: It will fit between regular studs in the wall, but it is almost 10" deep, so that would be the measurment you would need to know. Is it over 10" deep between the studs where you are wanting to install the speaker. I put mine below the TV that is above the fireplace, so I had an "open wall" to work with

**Q: are they good for movies ??**
A: Currently using this speaker as a center channel for 2 home theaters set up Dolby 5.1. I really like these speakers

**Q: I like having tv not to high. The center of speaker would be 77 " high if I place above tv . Will it be a downgrade from couch viewing at 14ft away?**
A: Place left and right speakers at the center height of the tv and center channel under tv as centered as possible. Depending on the amount of amplification you shouldn't have any trouble with the 14 ft distance. Place surrounds at the same height as front speakers. Mine sounds incredible even at a lower volume.
