Could some ks point me to advice/source to re-edge a pair of Allison 105 bookshelf speakers I just acquired.

The woofer has a tacky membrane around the outside which looked a bit frayed when I removed the grill. I touched it with my finger and loads more came away, doh!

thx

I have a pair of Allison CD8's that were great for years, when suddenly the woofer surrounds fell apart. Fortunately, Allison Acoustics was reformed and making replacement parts that aren't terribly overpriced. Go to:

http://www.allisonacoustics.com/

to find the parts. It would be great if you could test the drivers and see if there is a drop in replacement.

I have always wanted to try to use the Allison convex dome mid-range and tweeter in a new speaker, but can't get enough information on these drivers to design a crossover, and I have no test equipment of my own. Many years ago some people considered the Allison convex tweeter as one of the best designs around. It would be interesting to test the driver to see if its reputation still holds true.

Thx for the thoughts. Unfortunately Allisonacoustics want $40 each for the replacement 6" that was in the AL 105/110/120/125, plus shipping and import tax to the UK, which makes it prohibitive for cosmetically challenged s/h spkrs.

I did see somewhere replacement edges at $25-$30, but again with shipping and tax it gets a tad pricey.

I was hoping some enterprising hobbyist had figured out a way to fix 'tacky' edges on the cheap as the main body of the cone is in good condition.

Weird, I googled I don't know how many times and never came across this site. Just nothing similar that I can find in the UK. I'll look at this one to see how their prices on refoaming kits compare.

I googled around to see what I could find on this speaker, one of my results was someone selling a pair on craigslist for $25 that appeared to be in good condition.

I'd probably avoid doing any repair work like this, a recone or repair could easily exceed the value. It might be more cost effective to try and find a whole new pair in good condition if you enjoy the speaker, or something else completely if you aren't attached to them.

I acquired a pair of Allison 105 speakers in good condition in the UK. Apart from the usual problem of needing new foam support rings everything else was OK. It was my first time working on any speakers but in less than two hours ( total cost of £7 including glue ) had repaired the drivers. So don't be put off by unhelpful naysayers saying leave well alone, just measure the existing foam rubber and order on eBay.

Given the difference between $25-30 to resurround the existing loudspeaker and likely result in different T/S so won’t work quite well,vrs $40 for a woofer where someone already did the fixing with proper surrounds instead of random ones. Note that with no experience you can end up screwing up the woofers anyway..

I would just buy new ones and ask if they want teh old ones ack to refurb.

Speaker repair shops in the main will not be manufacturing parts such as foam suspension rings as it would not be economic on such a small scale, so they buy in. You don't need to buy " random " if you decide to repair your own you just need to measure properly and buy the correct parts. Some repair shops even produce very good videos to help you on a DIY project such as replacing foam or rubber surrounds. An average person with good DIY skills should have no problems at all.
