Crutchfield Customer Review (What's this?)

Considering cost, they are pretty flimsy.

Pros: Great for rough in install.

Cons: Costly

Worked great - still not happy about the price.

Crutchfield Customer Review (What's this?)

I bought these and then decided to read the reviews. Looking at the alternative solutions I felt I'd just been had after shelling about about $50 a pair for these since I'm a reasonably handy individual. I installed them anyway and now that I have installed the speakers I have to say I can't imagine doing the job without them. The drywall guys knew exactly where to cut and how to cut it. In the one hole they didn't clear out right the circle enabled me to finish the job. When you install the speakers you have very little lip on the mounting bracket to work with so messing up with a homemade solution is highly probable. Even still, I'm going to remove a star for the price.

Easy Installation, little flimsy

Written By SeanF, Chicago, IL on Thursday, November 06, 2014

Crutchfield Customer Review (What's this?)

I also installed the PB65 pre-contrcution brackets as well. My comments are similar for this model. Super easy to install, but not made of the best materials and are a little flimsy. That said, I do think these will help with final installation of speakers. Screws that come with these mounting brackets are too soft, and some broke when I screwed them into the studs.

Pros: Easy installation

Cons: a bit pricy

Crutchfield Customer Review (What's this?)

Great customer service led me to the correct speakers for both a 5.1 system and whole home audio. These speaker rings made it very easy to visualize the speaker placement and get the wire to stay where it needs to be. We haven't finished the speaker installation yet, so this review is just for the drywall rings - but so far so good. I agree with previous reviewers in that the price could certainly be lower, but for an old house with uncertain joist locations, it worked for us.

Just cut the drywall after construction and save the $

Pros: Easy to install

Cons: WAAAY overpriced for a cheap piece of plastic!

Useless item, don't waste your money

Written By Anonymous, NC on Sunday, August 21, 2011

Crutchfield Customer Review (What's this?)

Don't waste your money on this item! It does you no good. It does not mount the speaker no matter what any one tells you!!! The speaker does not connect to the mount or get any support from it. Use the template that comes with the speakers and hang for the sheetrock guys and they will know exactly what to do. I was told I could use these to hang speakers on my porch with a vinyl ceiling so I bought them and found out otherwise. The instructions specifically state that is not to be used as a mount, and it really can't. The speakers are meant to hang straight off the sheetrock. The product description is not clear and the tech told me it would support the speaker, but it does not. These guys are the greatest but this is a misunderstanding. You can accomplish as much with a pen and a piece of poster board and save the money.

effective but costly

Effective, but terribly overpriced for what it is - a piece of plastic.
