Worth the Price

Joseph from New Holland, PA on 12/29/2018

Installed these along with a set of the CDT5800 when I was finishing my basement. I can say that the combination of the speaker enclosure and the speakers themselves sound fantastic. I am running them as my rear channel in a 5.1.2 setup. If you are doing in ceiling speakers spend the extra money and get the enclosure, do it right the first time, it can't hurt. I did have to add some wood bracing in the ceiling so that I had something to screw into when I installed them. I also took it a step further and added some sound insulation above and around the speaker box, just to help prevent sound transfer to the first floor.

Pros: Great fit, awesome quality, serves its purpose

Cons: None

Well built!

Crutchfield Customer Review (What's this?)

Very well made enclouse. Built with heavy gauge steel. Be aware that your joists in the ceiling shoudl be 16" on center and not doubled up. In my case, my customer had an older house and the joists were reinforced by doubling up the beam. This led to a very tight fit, just barely made it. And I was not able to use the wire clamp connector. Instead I drilled a 3/8" hold from the top of the enclosure. This is absolutely no fault of the product but rather the house's construction but just letting people out there to check their mounting circumstances. For grin, I tried it in my house, which is much more modern and it fits perfectly. My house has wooden I-beam joists if that helps. The speakers have not been installed yet so I don't know the effect it has on the sound but I'm sure it would be much better than mouting the speakers freely in the ceiling.

While the insulation exceeds fire requirements, it also reduces the sound transmission into adjacent spaces by at least 10dB.

Compatibility: The ME-800-C metal enclosure is designed to fit all Reference Series in-ceiling speakers with 8" woofers. The inside edge of the ME-800-C's mounting ring is color coded to match up with the corresponding Klipsch installation kit size code.

Quality Construction: The ME-800-C is manufactured from high-grade cold-rolled steel and features a layer of insulation. It exceeds the one-hour fire-rating requirements and is designed to meet UL2043 requirements for installation in plenum spaces.

Q & A

Customer Q&A

Crutchfield asked  
Why did you buy this?

These came highly recommended. [ Gary R.  Dec 30, 2018 ]
I have Klipsch speakers in my current home. I am very pleased with their quality and price. The insulated box isnt something i have with my currently speakers and didn't know it existed until I found it on the Crutchfield Website. [ Jon  Jun 24, 2018 ]
Retrofit surround sound into an attic with blown-in insulation. These will keep the stuff out and help keep the sound clean. [ David P.  Mar 23, 2018 ]
New home build. Planning on an Atmos setup using Klipsch CDT-5800-C II speakers. [ Jeffrey  May 20, 2017 ]

4 questions already asked

They typically mount in ceiling attached to joists. I would suggest building a box to attach/enclose this in. [ Robert  Dec 29, 2018 ]
No you cannot. On the back side is an enclosure. Think of a kitchen sink but upside down. [ MK  Dec 29, 2018 ]
Design to be installed in preconstruction on your joists under the drywall. [ Jeremy  Dec 29, 2018 ]
The opening has a 1/2" lip extending down meant as an edge for the drywall. (An electrician would call this a built-in mud ring.) Thus there needs to be a 1/2 inch piece of some sort of board over the flat surface first to bring the speaker out beyond the rim. [ ROBERT  Dec 29, 2018 ]
The flange goes over the stud so you can nail it in (you can see the holes in the picture) [ Jeffrey  Aug 29, 2018 ]
This isn't meant for a sub. Subs have other enclosure for in wall use and are larger. [ Hyun  Apr 07, 2018 ]
The 9.8 in opening is large enough for most 8 inch, in-wall/ceiling speakers (I'm not using a Klipsch 8 in speaker, but it fits). It shouldn't be a bare speaker because it needs to press against the ceiling/wall to seal the space; the box has a small lip (green) that is inserted into the ceiling/wall hole. The box is about 17 in x 13 in x 5 in high, so it's about 2/3 of a cubic foot. While the base is nearly square, the box is not - there are holes in the base to attach to the ceiling/wall studs. The diagrams from Crutchfield and Klipsch show the true dimensions and shape (the inch values are correct, but there are errors in the metric measurements from Klipsch). [ David P.  Apr 07, 2018 ]
You need to read the manual or specs for the enclosure to get the width of the cut out and the height of the enclosure. The Klipsch CDT-5800-C II, which is an 8 inch woofer, fits perfectly. It's the exact combinatin and they sound great. I looked at a lot of different ceiling speakers from definitive to martin logan and they didn't seem like they would fit. Either two small or two big. [ eric  Apr 07, 2018 ]
Any any round 8" in wall speaker should fit. Subs have a different enclosure. It's about 15x16x5 not including the lip around the enclosure. [ Hyun  Apr 07, 2018 ]
Any woofer can be installed. The volume is 0.6 cubic feet. [ ROBERT  Apr 07, 2018 ]
