Long term repair of LSiM speakers?

in Speakers
Hello, I'm looking to get a good system for music only and have narrowed down to the LSiM 705s. But if I spend this kind of money I want to know that I can repair the thing 15 years from now if a driver blows. I'm more concerned about the woofers on these since they aren't circular, so I would assume it would be a lot harder to replace them with another brand if the original isn't available from anyone.
Any thoughts? Does Polk always support products or might you be out of luck and have to scrap your $1k speaker because of one part?

    If history serves as a guide, the answer is no.

    But there may be shops that can rebuild the drivers you could use

    You should be able to find woofers or other parts on eBay or equivalent, especially given all the 705’s that had serious cabinet damage during shipping. Of course, try to assure in the first place that drivers don’t blow.

    How many years would you give a driver cone before its dried out enough to be shot? It doesn't seem like anyone else worries about this, strangely to me.

    How long until your $1.5k investment is done due to age and inavailability of parts? I did use some pioneer speakers that are now 50 years old. Still working without obvious distortion, but certainly also degraded.

    The drivers in vintage Polk speakers are still working 35+ years later.

    I have a pair of Monitor 5A from 1983 and all the drivers work perfectly and are in excellent condition. A pair of 5B from 1984 and RTA-11TL from 1990. All drivers showing no signs of aging. I would think more modern polymer drivers would last even longer than the doped paper driver of these vintage speakers.
