If anyone on the planet can repair the woofers properly it's Bill LeGall of Millersound. Try emailing him and tell him your problem: Millerspkr@aol.com

He will be rehabbing the last 2 of my mids later this year. I also am doubly blessed as door-to-door for me is a 40 minute drive to hand deliver to Bill.

I use an SAE 2401 (250 watt/ch) with my Allison One's.  Gives them the "grunt" they need.

Thanks for reply Pete. My budget is around $ 450, but i prefer to find something from the catalog, are not very experienced in making these experiments.
Searching the internet, I found 2 interesting woofer, what do you think?
I enclose the translation of the original specifications of the woofer allison.

check out this woofer, and tell me what do you think:

So are these the scanspeak woofers you used, the 26W/4534G00?  Looks awesome.  So, let us know how your testing results come out.

I haven't been here in a while but my timing seems good. I have a nice pair of Model Ones and planned on testing the woofers and can post the T&S parameters. One of my woofers has a slight buzz when I play certain material like DSOTM. Bill LeGall of MillerSound swears he can rework the woofers and even replicate the coating so I was going to test a couple of them before he performs his "magic". I have had him clean up and reform a couple of the mid domes to where they look like new.
