Larrys Rings

I'll take a look, I am assuming those are the stickied posts. I don't have any more Polk speakers worth modding any longer (just sold some RTA12B's, that was my last really good pair of polks) except for my monitor 10's and those are in the closet and kept for nostalgia value, I'm not really interested in modding those. It will make interesting reading however. I just liked the concept and didn't know if there were rings made for non-polk larger displacement speakers like 10" or 12" woofers. Probably not the case. I will definitely use the foam tape in the future however, that is a great take-away.

I was away for a few minutes ,so your answer is yes. There are stikies that are under the Vintage Speaker title and then once you find one that is pertinent to your job it will go into depth that should impress any doubters. I was one ,ask anybody how stubbourn I was and now have modded my found SDA 2Bs to where I only need to send out the x-overs and then they are done. Many here also do their own x-overs,a bit over my head better left to Trey @ VR-3 Mods or any who do this work and can be P/Md.It really is great seeing the different model speakers and the mods that are applied. Go and enjoy some good reading.....

I've read a lot of it back when I was working on my RTA's but I'll check out the rest.
I do my own xover work, probably done 20-30 pairs (recaps) so far and it's not very tough even without an electronics background. I'll take a look, my bro still has a pair of SDA 2B's but I think he's kind of drifting out of audio and may not want to deal with mods. -
Larry, try to PM me a quote on a set of M12's(the whole lot)! I THINK I'm hearing some cabinet resonances that are pissing me off. I think this will help. I HOPE IT WILL HELP.Monitor 12's-RDO's and XO's done!

Other than the negative aspects to Mortite already mentioned, it was my experience that it has a negative affect to the sound quality.
I have the complete opposite experience with using Mortite, which was recommended 4 years ago. Speaking from sonic experience, it took the speakers to a whole new level. I am using mortite on my SDA-SRS 1.2TLs. Better bass and slam was noticed immediately. The cabinets were completely air-tight. There was no negative impact noticed in the other frequency ranges when using Mortite.
Others mentioned way back then that mortite had a better sonic impact compared to Armacel. I have not used the Armacel because Mortite was making headlines and getting glowing reviews here. So thanks to the recommendations on those in this forum, I already used it in my cabinets following from those here who had already applied it. Why is there a 180 degree change all of the sudden? Is winter now the new summer?
The one thing I will agree with everyones statement about Mortite: when it comes to removing your speakers to get back into the cabinet is that it will be a PITA, but that is because the Mortite is doing its job by becoming a sealant. It does its job well.Statistics show that 98% of us will die at some point in our lifetime.
The other 2% will work for WalMart. -
By the way Leftwinger - how did your SDA Upgrade Project come along? I have not had a chance to catch up with you since we spoke sometime last year.Statistics show that 98% of us will die at some point in our lifetime.

The only positive about mortite is that it got me to come up with the rings, as the mortite was pulling on the hardware, and was pulling them through..
Armacel is by far the better choice, and is air tight as well.. -

This was my experience as well, but, as with all things in audio, individual results will vary.PolkMaster1 wrote: »Why is there a 180 degree change all of the sudden? Is winter now the new summer?
Well, I haven't done a 180. I still like Mortite, I just like the ring/Armacell combination better. If I were modding a pair of speakers and rings were not available, I would use Mortite rather than Armacell or some other foam gasket.
I used Mortite from 2008 to 2011 with good results. I went from Mortite, to Mortite with rings, to rings with Armacell.PolkMaster1 wrote: »The one thing I will agree with everyones statement about Mortite: when it comes to removing your speakers to get back into the cabinet is that it will be a PITA, but that is because the Mortite is doing its job by becoming a sealant.

As I noted in my stock foam seal vs. Mortite vs. Armacell review, Armacell can make removing drivers a PITA also, but not to the degree as with Mortite. When I rewired a pair of CRS+s recently, I had to use a pry tool to remove the Armacelled drivers that were stuck tight to the cabinet.Proud and loyal citizen of the Digital Domain and Solid State Country! -

Thanks westmassguy and PolkieMan on the armacell link. nice to know i can get it locally. I'm starting to work on my srs 2.3's with the donuts. I've had these for a few years and have done nothing to them. Just found this site. What a trove of information. I'm hoping I can get a set of Larry's rings. I broke the binding posts on one speaker during a recent move and will be replacing those. That is my most pressing need.

Yes and no.
That's the right product but wrong width.
2" is way to wide and you have to cut.
Get 1/2" if it's available.
I don't remember what I got but I didn't have to cut the width.

2 inches is the smallest available width. The original purpose of Armacell is to insulate pipes, so a 1/2 inch width would be ineffective for that purpose.The Gear...

Yup, I've always had to cut mine. Not that big a deal, its easy to cut.

Thousands of years ago, I needed to make gaskets for SL2000 tweeters. At that time, I was working for the Bus company. We got seats for City Buses each one wrapped in thin sheets of closed-cell foam, and enclosed in a huge cardboard box. We threw out enormous quantities of both foam sheet and cardboard, with management whining about the disposal costs. Raiding the dumpster produced as much foam sheet as a man cared to haul home. Think single pieces as large as a big bath-towel--these being the ripped 'n' tattered remains of sheets originally larger than bedsheets. Yup, closed-cell foam, gasket-thin, free to anyone who bothered to carry it to their car. Took me years to use it all, cut it into speaker driver gaskets, or to wrap packages with it.
The primary issue is that every aftermarket foam solution I've seen uses thicker foam that the original Polk gaskets; at least thicker than the used-and-compressed original gaskets I've seen. How thick the Polk gaskets were when new is a mystery to me--but I think they were exceedingly thin.
Thicker foam may seal better--more effective at preventing air leaks--but it may also isolate the driver from the cabinet which is bound to affect sound, although I'm not qualified to predict how the sound is affected.
Any way you look at the closed-cell foam gaskets, they beat the hell out of rope caulk (Moretite). I used another brand (Dennis) of the same product; it applies nicely and works well--but it's a GD NIGHTMARE to clean up when removing the drivers again. -

True but Armacell will compress to paper thin given time. So it ends up being the same thickness give or take, you just have to come back every day or so for a bit and re-tension it.
Heck I used the stuff on my Infinity RS-II mids, woofers and the removeable xover panels.Any way you look at the closed-cell foam gaskets, they beat the hell out of rope caulk (Moretite).

Agreed!

Exactly and that's why I've always said as long as the original gaskets are not damaged there's no point in changing them.

LOL... but there not a reason to do a LOT of the stuff we do, so it is what it is.

Does this foam tape work as well as armacell?
It comes in 1/4" as well as 1/2" width.
