Should I recap my speakers? If so who can do it?

Thanks also to @marqmike !

I have learned a great deal reading Timlub posts and greatly respect him.  

The parts costs quoted seem reasonable. I did some speakers for my neighbour, cost about $1000, and dramatically improved every aspect of the speakers' performance.

I'm retired too, and it's my hobby too, but I'm not in the business. The posters above should be able to help you a lot.

But don't go cheap on the treble crossover capacitors. I would spend the bucks to get film and foil, preferably styrene and tin (MIT sells a good one) on the treble signal path. In this case, you get a LOT for what you pay, maybe the best bang for buck in the whole audio chain.

I would contact Peter at PBN Audio. He is very honest, he has built many a speaker, amp, pre amp, turntable.  Will not blow any smoke up your speaker so to speak. He is a old world craftsman when it comes to the repair or making new. With lots of electronic knowledge.
Good luck

Just read this thread and I gotta say it's really cool that grannyring and timlub chimed in to help the OP out. It's a testament to the the "brotherhood" of those that are so well versed and experienced to help out a fellow audio appreciator in need.
