Crutchfield Customer Review (What's this?)

these are great. They were really easy to install between rafters and it was super easy to cut out speaker hole once sheet rock was installed. A must have if you are installing prior to sheet rock.



Just installed them during basement finishing project

Crutchfield Customer Review (What's this?)

So far so good. Bought these to assist with installing the ceiling speakers during the basement finishing project. Drywall is going up today and the guys have used these as a guide. Speaker install is still a few weeks away.

Pros: Easy to use.

Cons: None

A must for new construction

These are a must if you're dealing with new construction or bare joists. It simplifies wiring location, drywall cutout and installation.

Pros: Easy installation. Puts speakers exactly where you want them.

Cons: None.

Crutchfield Customer Review (What's this?)

Looks nice gives a good backing so it doesn't crush the sheet rock

Pros: It works very well

Cons: Had to really support it with 2x4 to flimsy for the money

Would not have installed without them.

Crutchfield Customer Review (What's this?)

I would not have installed the speakers without these mounting brackets. The speakers have clamps that turn and apply pressure to the rear side of the wall pulling the speaker tight to the outside of the drywall. These brackets stop the speaker clamp from simply crushing the drywall and rendering the wall useless to holding the speaker in firmly. They could mount a little better to the studs before drywall is put in. They stayed in place and the drywall installers knew exactly where to cutout and easily cutout around the mounting brackets with their rotary drywall cutting tool.

Pros: Keep speakers firming mounted. Help cut drywall exactly to size.

Cons: None

Easy way to do ceiling speakers

Written by: TomS from Blue Ridge, GA on July 12, 2014

Crutchfield Customer Review (What's this?)

These are an excellent way to handle ceiling speakers during construction. Very easy to install.

Pros: Simple, easy, quick

Cons: A little flimsy but, doesn't really hurt anything since it;s just meant as a way to locate speakers prior to drywalling

Flimsy, expensive. Somewhat useful.

Written by: Scott from Honolulu, HI on October 2, 2013

These brackets are flimsy, they are impossible to get square and keep square as you screw them into the studs. This means the drywall holes will not be totally square either - especially if they use a router which will push the bracket around as they attempt to "outline" the bracket in the drywall.

I have not installed the speakers yet, but I am imagining I will have to make the whole square with a drywall knife when it comes time for me to install them.

The only reason I bought these was so that I could very easily show the builder where to pull speaker wire to and to have the drywall people router the holes for me. Otherwise I would have to rely on them to measure out and cut speaker locations and I did not want them to mess it up.

Pros: Useful to designate speaker location for wire pulls and drywall install.

Cons: Flimsy, impossible to get and keep square. Expensive for what you get.

Worth the price

Crutchfield Customer Review (What's this?)

These are worth every bit of 50 bucks. Would have taken awhile to fab up and they guarantee the sheetrock guys know where to cut your speaker holes.

Pros: Fast simple and error free

Cons: Just a templet,not for structural mounting.
