Makes install easier

Written by: Jeff from Washington, DC on April 21, 2016

Crutchfield Customer Review (What's this?)

Product is a good one. As my installer said, "you can pay the cost now for the brackets, or pay more once drywall goes up when the labor is more intensive to cut out the speaker holes." I opted to pay the costs up front so I could see, and approve, exactly where the speakers would be placed.

Pros: allows for visual "validation" of where speakers will be placed before drywall goes up

Cons: expensive for just a plastic ring.... it adds 30%+ to the cost of the speakers.

Great for wall mount but not ceiling

Crutchfield Customer Review (What's this?)

These brackets are plastic and very flimsy, only 1/8" thick. The price is high compared to the quality. If using them for ceiling mounted speakers don't expect them to support any of the weight, your ceiling drywall will be doing all the work - again the plastic straps bend too easily for that purpose. It seems that are simply to mark the location of the speakers for your sub-contractors to know where to cut the holes and run the wires. Now, for wall mount speakers they will support the weight as the straps are 2" wide and do not flex in the vertical direction when mounted in the wall.

Pros: lets contractors know where to cut holes and run wires.

Cons: Too pricey, and not weight bearing for ceiling speakers.

Don't hesitate!

If you are building a new home these are a must. Made the job easy for the drywall guys so they knew exactly where to cut the holes for the speakers. It's a must if you want to make sure everything is done correctly.

Pros: Easy installation

Cons: A bit pricey

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 from Chicago, IL on November 6, 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

Useless item, don't waste your money

Written by: Anonymous from NC on 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.

Q & A

Customer Q&A

Crutchfield asked  
Why did you buy this?

These make new home construction a breeze. I'm in to wire and place speaker frames in the desired location. I return after the painting is complete and my wiring and speaker holes are where they are suppose to be and the cut out holes are the correct size. I simply install the speakers, connect the equipment, label the connections, test, tune, and I'm done. [ Thomas  May 09, 2016 ]
Seemed like it made speaker install easy. Hopefully it does. Kinda pricey for a piece of plastic [ David  May 05, 2016 ]
Speaker placement in new construction home. [ Mr.  Feb 17, 2016 ]
Take advantage of preconstruction opportunities to secure in wall speakers with the optimal stability. [ Eric  Jan 23, 2016 ]
Was recommended for new construction. [ Amanda  Jan 01, 2016 ]
to make install easey [ JASON  Dec 08, 2015 ]
Part of kitchen remodel that included replacing the dry wall ceiling. Purchasing the mounting brackets made installing Polk speakers easier. My contractor installed the wiring and the ceiling brackets and I did the rest. [ Jeffrey  Dec 08, 2015 ]

2 questions already asked

they make things easier, but not 100% necessary. [ Daniel  Jul 13, 2015 ]
i had the same concern, but they did help since the drywall guys can fit around them nicely. also you can tuck and in my case strap tie the speaker cord to them so they dont get lost in the process. i think i was able to get an open box one which where a little cheaper so check there. overall, it will make your life easier during install, and if the sheet rockers screw it up, they can find and fix it. good luck. todd [ TODD  Jul 13, 2015 ]
If you are having sheet rockers installing over framing then yes it is worth the money to get a clean finish. You can cut the holes in later but you'll need to note the locations of the wires. [ Reed  Jul 13, 2015 ]
Makes installation a whole lot easier and cleaner. The speakers sit more secure on the brackets versus being screwed into drywall. [ Christopher  Jul 13, 2015 ]
Not necessary but it's nice to know the speaker is being held up by more than the drywall, the straps nail into studs. I feel it made for a cleaner install also. I went with Polk speakers so they were pretty heavy. I installed them two yards ago no problems. Worth the $$. [ JACK S  Jul 13, 2015 ]
IMO, you don't need them. However, they do make it easier to cut a clean hole. I used them because my builder was a tool and insisted on brackets. I think he wanted them there as guides for the ceiling Sheetrock guys. Otherwise you get a hole perhaps off center. [ ERIC  Jul 13, 2015 ]
Not necessary, but it does make it easy for the dry waller to router the holes exactly where you want the speakers. [ Thomas  Jul 13, 2015 ]
Yes [ JACK S  Jul 13, 2015 ]
It should fit if the speaker is 8" round ceiling or wall type. [ Thomas  May 27, 2015 ]
