Infinity Beta's replacement parts

I have the option to buy Infinity Beta’s for a reasonable price in a near-mint condition. On the one hand, I always wanted to own some great Infinity speakers, but on the other hand, I worry that if a SEMIT, EMIT, or EMIM were to fail I would be stuck with unrepairable speakers. My question is therefore, if someone, maybey you @Paul , knows where I could get my hands on some replacement parts in the future or what drivers other than the original one’s from Infinity would be suitable as a replacement.

I hope someone answers soon as I don’t have all the time in the world to make up my mind about whether I buy the speakers or not.

You can check on eBay for used Infinity parts. I got a lot of spare emits and other Infinity parts for my RS 3B in great condition from ebay. I’ve seen reconditioned parts like emims for Betas on ebay.
