I’m laughing to myself inside because my AR9s are also stored in my entry hallway near the shoes!

A lot of people who cut/shape foam use an electric knife.
I was thinking of this, but I don’t think such a wide knife could cut a sufficient bevel on such a small diameter.

I found these drawings in a post from 2004 on here. The only thing I can’t seem to replicate is the 45° edge of the inner diameter. Does anyone know how this might be done?

I know this is an old post, but I wanted to add my results in response.
When restoring my 9s, I also wanted to fill the empty surrounds for the UMRs. Since I had ones around the tweeters, I matched the foam density and ordered a freakishly large piece on Amazon.
The foam was grey, but I had a plan. First, I trimmed its outer rectangle and trial fit. Then I searched around the house for a disc to use as a template for the driver’s outer surround. I ended up using the lid for the bean hopper on an espresso grinder. Then I shot it black with SEM dye.
I think they look great.
Since I have so much extra material, PM me if you’re interested in this.

I added 1/2 closed cell foam around the upper midrange.
Has anyone else here made mods as I have and what's your experience with these and others?
The AR9's are just fantastic speakers.

Yes, I had no idea that the lead was so fine and that it was really just right there. Hindsight is just so clear, isn’t it?

RoyC and lance G have asked me to cut off the dust cap to see if I could spot the damage. The break is clearly seen. Yikes

it makes greater sense to pass the whole driver to a "professional" who can carry out the work on your behalf.
Yeah, I think that’s what I’ll do, in light of the fact that RoyC has already offered to do it. I’ve read about attaching these leads and it seems like a doable thing, but RoyC has done many of these and I trust him implicitly with this valuable driver. Besides, I think I deserve an award for completely rewiring, recapping and also reforming these two without laying them down. I soldered everything while they were standing upright! The first one sounds magnificent. Shortly, so will the other.

Did you put a battery or a test signal on the removed woofer terminals?
@RoyC could possibly repair it without replacing the cone. Send him a private message on this site.
I checked out the driver with the battery test and nothing. There is definitely a continuity issue.
I think I’ll ask RoyC what he thinks.

I’ve had direct experience with Simply Speakers on a woofer continuity repair, involving a voice coil lead. That’s a priceless driver and I would trust them to get it working
Hi,
Are you saying that you would go to them again regarding such an issue?
-
Thanks for the thoughtful reply. This is why I like this forum so much. There’s a tremendous amount of information and great, like-minded individuals in terms of keeping these great systems going.
I have not tried the battery check yet, but I will as soon as I get home. The memory of poking through the area of the negative lead just hit me like a ton of bricks and I stopped wondering what happened.
I definitely don’t want a recone, so I’ll avoid Speaker Exchange or the like. I’ll probably message Roy to see what he thinks.
Thanks so much!

I’m restoring a pair of AR-9s I got in eBay for $400 and I thought I was finished with the drivers, wiring and caps. The first unit went well and tested in proper working order. The second one was finished last night and I reassembled this morning. It sounded okay, but placing my fingers on the cone of the right hand woofer indicated that it was not working. I removed it and looked for obvious signs of disconnections or phase, but everything was looking correct.
Then it hit me. During the removal of the dust cap, I must have been in Neanderthal Mode (hey, it happens) with the X-acto blade and I’m pretty sure I sliced the thin wire lead to the spider and voice coil. Ugh!
Is this a lost cause? Is it a doable repair? Should I take it to Speaker Exchange in Tampa?

I actually took down the article for now because it is likely to be publshed next month (not for sure, though).

I would like to read this article. Where is it published?

I'll never forget the look on my mother's face...mouth wide open in shock...when we hauled those huge boxes into the house.
The best description of the inimitable presence of 9s that I’ve ever heard.
This made my day.

I know this is an older thread, but I’m curious if a final solution was reached.

Is this driver hand marked out of phase? Usually AR marks the + connection with the red dot on the adjacent label. Has something changed during re.coning?
Many Thanks to Roy Champagne

Yes, he sure fixed me up on a destroyed woofer lead. I was so grateful to him that I threw in a $50 Whole Foods gift card, which his wife snatched away from him!
