I do get vtv..’s concern. If you have (and are willing to part with) the money, buying new is preferrable. However, given the 5 and 6 digit prices good (new) full-range speakers command these days.. buying used can save you several of those digits.. but you definitely do have to go see them first, personally. You have to listen to them with good, educated ears. This means traveling. That is most likely only a 3 digit expense, hwvr.
Most often, given butyl surrounds (not foam), all you’ll need to do for service is ferrofluid (which is simpler on woofers and tweeters than it is on small mid-ranges). For those you’ll need an expert.. but again, this is only a 2 or 3 digit expense. Capacitors are fairly robust on good quality crossovers.. esp if they’re under 20yrs old. I’ve gone through my original film caps on my 25+ year old x-overs boards, and suprisingly, they all still measure within what’s printed on the outside.
