Speaker boxes. To rebuild or not to rebuild

Morning gang,
I picked up a free set of Technics 3 way SB-2860. I cant get any good sound out of them. No bass and all tinny.
Is there a speaker rebuild kit on a website that I can buy drivers, mids and tweeters as a kit? Any recommendations? These wont be my premier set, so we can go average on the expense. But, I think the cabintes are in very good shape and it would be a waste just to toss  them?
Thoughts?
Thank you
Marty

Um, not worth spending a lot of cash into, BUT, totally worth using them to learn about speakers! :)

If you wan to, come over to the DIY forum where you'll find a lot of peeps who will help you do just that.

It could be a simple bad wire, or blown cap/resistor.

As a learning exercise, worth fixing. As a restoration project, not so much.

Best,

You could as saiod, Frakenspeaker them.

Or contact Technics and do the rebuild yourself from orig or current drivers and x overs.

You might get lucky and find that technics still has a line on orig parts for them. Some makers do. Some do not. Wouldn’t hurt to make a call and find out.

As was said, there’s a real learning experience in there somewhere just waiting.

Great great suggestions. I am currently performing "open box" surgery to learn and observe the operation of a 3 way. After reading countless threads on many topics, I feel that I can put them to use as donors and then put them out to pasture. I would rather spend the $ on FS52 or Elac F6.
Thank you to all!!

If the cabinets are in a very good shape and you can find the crossover data, do some research to find the right replacement drivers from the site mentioned earlier and you could end up with a great pair of speakers and learned a lot along the way. Win win.
