How to install in-wall KEF ci130/160s?

[Nootmuskaatje]

Hello! I want to install some in-wall kef speakers for my surrounds for a higher WAF. Sadly our walls are all concrete, so it will require a bit more effort than I'd wish. We do have to get some holes made for extra sockets soon and get the walls plastered, so I want to get 2 holes drilled for in-wall surrounds while we're at it. But how do you even mount them? I can't find much info or a tutorial on how to mount a KEF ci130qr/ci160qr or qs. Is there something like a mount sold with it for certain walls? I see some videos of different in-walls where they just click it in, but those are on drywalls and not a solid block of concrete.

Any help would be much appreciated!

Have you looked into their (and other brands') on wall models?

I think that might be your path of least resistance.

I've seen the T101, but that even drops off at 200Hz and is quite larger. I'd atleast want it to go down to 100. But flush with the wall is better, I can paint the grille in the colour of the wall. Will be a harder job with on walls.

There is actually a manual:

And a cutout template:

Thanks! No clue how I couldn't find that. Sadly it doesn't show solid concrete walls. I can't use those dog legs or what they're called in concrete.

I think what you need to do is make a bigger hole and cover it with drywall. Then make the cutout in the drywall.

The KEF CI speakers are all designed to use the air volume in a typical wood framed stud bay as an integral part of the system. There is a good reference sheet describing minimum and ideal air volume for each of their CI models.

If you need in-walls, you're going to want to look for speakers that have an integral back box (not KEF). Triad is a good option among others (depending on your budget).

That explains a lot. Those Triads are pretty large, I preferred the kefs since their drivers match and especially because it's just a small single coax. Are there other manufacturers with these kinds of in walls?

If your walls are concrete make sure they are not part of the structural building's skeleton (excuse my poor English).
If it is you will find out (the hard way) that there is steel inside also.
(I was paying attention to this stuff when my house was built,just out of curiosity and since then I hesitate to even put a nail on one of these walls)

They're all indeed reinforced concrete walls, so the socket holes will be made with specialised equipment as well. I won't make them myself. We're getting a professional to make the holes for extra sockets, so might as well ask them for 2 more for the speakers.

Have a look at this solution for your concrete walls.

It's quite involved, but it would work with the KEF speakers (CI 4100 might work better with the recommended enclosure size).

I just learned that the wall in question is a carrying wall (not sure if that's the correct English term), which means I can't even drill such a large hole into them. So I'll have to find another way, maybe some small and slim bookshelf which goes down to atleast 100Hz.
