Acoustic Research 302 mid range trauma..Please Help

I think the 302, 303, and 338 all had the same midrange.  I bought a pair of 338s and a pair of 303s from accessories4less about 25 years ago.  The 338s were better than the 303s IMO.  The big 12 inch woofer combined with the little midrange wasn't a great combination.  They sounded kind of slow and indistinct.  The 338s were nice, though.  There's a pair of 303s on ebay right now.  I think I gave mine to one of my sisters and she's probably not using them, I should get them back.  They're apparently worth a lot more than I paid for them in the 90s.

they repair ar-3 mid ranges

they seem quite involved with ar 3, 3a ...

well, you just need patience to find oem replacements.

any history of people substituting a different mid?

pair in Italy for 300 euros

you would need to negotiate shipping, or some sort of drop/pack ship similar to ups pack and ship whereby the seller simply drops off unpackaged item in your name, that's how I got one of my pairs of AR 2ax's. , but here in usa.

I have a small hoard of mostly vintage high end audio and it's a passion I've had for a very long time so these being a rare model of speaker to begin with and from one of the more iconic brands and the fact they do sound very good and I've had the crossovers upgraded using expensive capacitors,  I'd much rather keep them as a pair of my regulars than spend the 5 or 6,000.00 it would take to buy anything new that would equal them..Or the close to 2,000 it would cost for something used with how everything has quadrupled in price since I bought these  : ) as one example I also have a pair of JBL 4312A's, L5's, Monitor Audio Silver 8's and they, to my own opinion, aren't as enjoyable to listen to..I'll add that I'm not in the financial class to really be into this audiophile world and what I've been able to acquire has been over at least 25 yrs and I do my best to keep everything I have in like new condition..Sorry, I didn't mean to say all that, nor am I upset at your question, but I guess I just got started and well........

I restored two pairs of AR-2ax’s, and love them, never hear 3’s or 302’s

if you prefer the allison 2’s and more prefer the kappa 8’s, what makes you want to fix the least preferred damaged ones that are very old in any case?
