Yep, you're correct, it's either plastic dowels or screws depending on wooden tops or black plastic tops. There's two types of wooden tops I've had too, ones with and without painted sides. If possible I'd just like someone to post a picture of the screws for the black plastic tops as I've mixed up my screws from several sets of speakers as I wanted to treat them all for rust. Dimensions would also help too even if it's just having a ruler placed next to it.

I have a set of AR93Q speakers with the black ABS plastic tops but mixed up the screws which secure the top in place when I was refurbishing them. Could anyone give me the measurements of the correct size wood screws to use. I don't want to ruin the threads or punch through the wood when I put them back together. Thanks!

The light blue Interlec caps are probably original. I have seen them on a number of later speakers in the same range as the AR8 - AR9 range here in the UK.

Was my understand they had different amounts of ferrofluid in? So you could use a 92/925 in a 90/9 but not vice versa.

Madisound in the US have 1000uf and 500uf caps. I've imported stuff from them before. Bennic used to do suitable caps but I couldn't find any when I did my AR9s last year.

If the break is on the surface you could scrape away some of the coating and try to solder some fresh wire. I have a fair number of AR tweeters needing repair, most break on the surface from being store in less than optimal conditions rather than being overdriven.

If you ask him for the STL file then you could use an online 3d printing service. I'd happily print them for you but I'm in the UK.

My advice would be to refrain from trying to remove the acoustic blanket and instead mask it off and place plastic bags over it. Be careful with the amount and strength of the masking tape as it can pull up the fabric. I have a set of AR92s in my garage where I removed the blanket. It took a lot of white spirit and scraping. I don't recommend it. I didn't do this on my AR90s which I sanded and resprayed. The paint went right up to the blanket, even with the masking and came out great. The 92s were a barn find so they haven't received any more thought or love yet. Can confirm two wood screws under the sticker on the front too.

Did you mask off the acoustic blanket strips?

I just finished refoaming a set of these. They sound great, well worth restoring 👍

They look closest to AR 8BX speakers to me.

+1 for in place. Try not to burn yourself on the iron too much ?

Does anybody know the PPI of the original foam in AR9LS/LSI bass chamber? Mine turned to mush before getting a measurement. I'm thinking of going with 30PPI but thought to check here in case anybody knows the actual value.

I'm also interested in this. I have a number of tweeters, 48ls and 28s spring to mind which I would like to re-coil. Also in the UK. If you can provide any hints in removing the old wire and applying the new wire that would be great. I'm also pondering a number of woofers. So far only found the correct spec wire for those.

I'd also be really interested to hear about your re-cone efforts and which parts you used. I have a 11" unit here where the spider is torn away from the cone slightly so may be opening up another thread to get some opinions on a fix.
