They say speakers drivers age, but I have a pair of 18yo DM302s that sound good. If it were me, I would fix the tweeter. I have heard the Titan. It is a good speaker and I personally don't like throwing stuff out that be fixed easily. The opportunity cost of $120 isn't much, and they could be sold later.
Paradigm Titan v3
I have a pair of these speakers. Years ago I damaged the tweeters. I now find myself needing a small bookshelf speaker and pulled these out of the closet. I reached out to Paradigm and they connected me with a local dealer who has given me a quote to fix both tweeters for $120 installed. They will install 2 new tweeters. My question is whether it is worth the money to fix them given how old the speakers are. They didn't get much use because I blew them not too long after buying them. However I recall that I probably did not pay much more than $200 to $300 max for them when new. So, what do you think? Am I better off just buying a new pair of speakers like the Energy CB-10s for about $95 more or will the speakers work just fine for many years to come after being repaired? I welcome any and all thoughts including those that want to tell me I am an idiot for posing the question in the first place.
