HI, I just left the drivers on and found glasses that are around the same size to glue the foams to the drivers. They apply just enough pressure and it is constant all the way around.  I let them dry overnight and have also used the CX100s for the CX50s. They are the same woofers. As far as I remember, goodhifi have also an online video or photos showing how to do it

Hello,

Suggest you get in touch with 'Medogsfat' (Chris).  He is a whiz with speaker renovation & also very helpful

Just doing some CX100's myself at the moment. What I do is glue the inner part og the ring to the cone. Leave it for 24 hours with a suitable size cup and some weight on it. Then do the outer part to the frame and leave that for 24 hours. Never had any problem so far getting pegs to hold it in place. One other thing I have found useful, is I connect a 1.5 volt battery to the speaker. This pulls the cone in squarly. Then I peg it in place and disconnect the battery. 9 times out of 10 it is in the corect place and no scraping can be heard if I bress the cone in.

thanks very much everyone for the useful replies...i shall give it a try and keep you posted..

We all do this slightly differnetly I guess!  I prefer to take the drivers out of the speaker to get better access and not let bits of foam drop into the baffle material or the speakers casing. Ihave found using 20+ clothes pegs (ie all round) helps if you cannot find a glass of the right diameter.

I also prefer not to risk scratching the aluminium casing (though of course that may not apply to old second (third, foruth or fifth) hand speakers.  It always saddens me when I see the condition some people allow their B&O kit to become.

Looks like we all do the same thing.

I use a glass of the correct diameter to hold the inner part of the new foam ring onto the cone and leave overnight. I'm lucky enough to have a couple of old defunct CX drivers (which I have removed the surrounds & cones from) which are the perfect thing for weighting down the outer edges of the new foams while the glue sets. I also use a 1.5 V battery to centre the speaker before allowing the outer of the rings to set. I also test the centering after about 5 minutes of the outer edges being glued which gives you the chance of resetting them if there is any slippage. You can test for correct centering by feeling for any rubbing by simply pressing the centre of the dust cap in a straight line inwards. If you feel any rubbing no matter how slight you will need to recentre them as they will not only sound horrible but wear out the drive coils in no time.

Brian, I know what you mean. At the moment I am in the middle of respraying the cabinets aswell as refoaming the Drivers. These have to be the worst cabinets I have seen on a pair of CX's. They look like they have been used to play football.😡

Just like most in this thread I am doing a pair of cx100's right now and cut some wooden disks that I cut to the exact size and weigh down. ( This would be my 12th pair that I'm refoaming...).
However, the pair I'm doing now is in that clear (brushed?) aluminium. Anyone got any ideas on how best to polishing them up ? 

I have resprayed many myself, but I would like to keep these in their (more-or-less) original state.  Their condition is not that good but they're for my own office.

Thanks in advance
