    I know these things do exist but they are a little hard to find. Has anyone got any experience of them ?
    I’m contemplating reducing the size of the current cutout.

    Probably just two solutions to this I think.

    1. Complete repair and replace a section of plasterboard around the area then make a new cutout.

    2. Replacement speakers of same size.

    Probably not the proper solution you're after, but you could use some mdf rings to reduce the opening.

    I see where you’re coming from with that. It’s similar to what would be done for a car install and I’ve done many of those.

    The outer diameter larger than the current cutout, then the centre cutout to the size that I want. Fix this to the underside of the ceiling. Then it’s a case of filling the inside of the ceiling so that the legs of new speakers can fix into something. Possibly another MDF ring at about the depth of the plasterboard with outer diameter the same size as current cutout and the inside diameter to the size I need.
    There would just be another ridge further out than the speaker grilles. That would be about 4-6mm I guess.

    There will be a couple of ways to do it, either the option you said, or a ring of 12mm mdf so the speaker would clip straight in, like it would on 1/2" plasterboard, it will have a thicker visible ridge, but easier to do.

    Got ya, yes much easier to do. I would need to try and check if there would be enough room on the inside for the fixing legs to swing out and attach before hitting the plasterboard. If that makes sense.

    Off the top of my head, the neatest solution would doing it your way.

    Use an mdf reducing ring in the hole, as you can get your hand in the hole you could fix the ring in place using screws through the ring into some wood battens above the plasterboard, speaker legs permitting of course, then you could use pretty much anything as the trim, 4mm mdf etc, could just be stuck on with no visible fixings as the ring is doing all the load carrying.

    Quick sketch of the ring and battens, they could be fitted in a couple of ways to accommodate the speaker legs.

    Most definitely not to scale!

    Top man, appreciate the help :smashin:

    I guess the reducing ring could possibly be directly fixed to the outside trim, then screw the trim to the board. Probably more secure with battens though in hindsight.

    The battens would give you a strong fixing without seeing any screws.

    You could source anything for the trim, mdf etc, I would just stick that on as it's lightweight and not holding anything, will also keep the whole thing looking clean and fixing free.

    Someone will probably post a purpose made solution after all this:rotfl:

    Yeah exactly, it could be something as thin as possible as it’s only acting as a cover up.

    It should work great if you decide to give it a go:smashin:

    Definitely less hassle than reboarding and skimming bits of ceiling!!:eek:

    Oh yeah, for sure.

    You can get precut circles from a few places, I’d just need to cut the centre out to suit and do all the fixing. The battens would need fixing down as well to prevent any movement. They wouldn’t need to be too thick either tbh.

    A few drywall screws through the plasterboard into the battens will keep everything in place, will be covered by the trim as well!

    You've probably done this sort of stuff before, but just incase, make sure you drill pilot holes to stop the battens splitting.

    I'd make something like this out of MDF. This example is to fit a 204mm B&W Ceiling speaker (6.5") into a hole that was already cut for a 253mm (8") one.

    Make the material thickness the same (or just slightly thinner) than the existing plaster. I'd just glue it in place with gripfill or something - that way you have no fixings visible. Split the ring in one place so you can feed it up through the hole.

    Or get some speakers the same size or bigger than you already have ;)

    Thats the kind of thing that I was looking for. But I thought of fitting it from underneath as oppose to inside the ceiling. Less repair to do that way. And as for me making it, I don't have the tools to do so.

    I hinted at a similar thing here.

    I could get the circles precut and just cut out the centre accordingly.

    I could get another large ring to go on the inside of the ceiling, marry it all up and fix together like a sandwich :D

    That's exactly what I was suggesting - two rings, one bigger than the other glued together.

    The bigger one will then sit above the ceiling and the smaller one will protrude down through the existing hole and be flush with the existing surface.

    Looks like another option, as long as you can get the larger circle through the smaller hole in the ceiling?
