I agree that the best way to go is to shim, I just believe in some instances, using a battery is an acceptable alternative.

Soren - I also found that no matter how clean I thought I had the speakers, on at least two of them I had some left over old adhesive that rolled down the face of the cone as I was gluing the rings in place. I would have hated it if they fell into the voice coil gap. I have no idea where they came from. I do shim larger speakers, like the woofers in

I think it comes down to this - at least with smaller woofers - with a battery and careful clamping you could be right with the placement. With shims, you know you're right. I'm a lazy SOB, but I'm careful, so I used the battery method and kept checking my work to ensure it was properly centered. Another six CX100 woofers successfully repaired

Sounds like a great solution all the way around!

I think this is one of the best things about B&O - the sound quality is superb, the user interface excellent, and the build quality outstanding. I really don't feel the need to 'tweak' anything in an attempt to make improvements. I just sit back, relax, and enjoy the show.

Like others, I owned some audiophile equipment before moving to B&O. I had some H.H. Scott, Fisher, McIntosh, and Dynaco tube amps, a Lexicon Processor, VTL Maximal Preamp, but all I've kept are my Vandersteen 2Ci speakers in my main listening room and my Grado Headphones. I was never able walk across my room without picking the sound of my

That makes sense. I guess I've just been lucky up until now, however I have used shims on larger diameter speakers in the past. I should always use shims to be safe.

I am refoaming three CX100s this week. I really had a tough time getting the old adhesive off the frames. The cones were not too hard to clean off this time. Now I'm at the point of deciding to use the battery method or to shim? It seems to me the spiders help hold the voice coils in place and there is not enough movement to the cone to throw it

Only the woofers suffer from foam rot. The midrange has a rubber surround. The I was able to refoam my pair without issue. Rather inexpensic

I just bought a pair of teak S-45.2 speakers with stands in very nice condition. I also bought a set of 3 CX-100 speakers that need a re-foam. I plan to use tham as the LCR speakers in my bedroom home theater, with my CX-50 speakers doing surround duty.
