Hello Marcas,if there that old you might want to think of a complete rebuilt, including new drivers and corssover parts
Start by accuratly measuring the internal volume (might need to use sand if you arn't confident)
Buy Vance Dickasons book "Loudspeaker desing cookbook"
Then get interactive speaker desinger from: http://linearteam.iwn.fi/winisd.htmland go to www.madisound.com to find current specs on drivers, plug them into winISD and fiddle around to you find somehting that works.
If you go to all the trouble of new woofers, at the same time do the midrange and tweeter (assuming its got a midrange)
If you do go down this path of putting new stuff in an existing box, which is your getting your toes wet for next building your own speakers from scratch, stay with paper and poly cone drivers for you first go. Paper and poly are so easy to work with, you almost can't go wrong.
The more reading you do (both books and on the net) the quicker you will be up to speed.A WARNING though, once hooked, you'll wanna keep building speakers, even though you don't need or have room for them. I had this problem till someone offered me a job building them. I was so bad i'd go to bed imagining crossover designs. :)
As to that small gap between the magnet and voice coil, this is a good thing when they're new, as they work better . Drivers 15 years old are "Normally" past there usefull life. The biggest advances have been made in tweeters, and i'd bet you a beer that your tweeters are best now used a paper weights.
Anyway, hope this helps if you (or anyone else for that matter)are thinking of doing something about old speakers.
Post here again or eamil me if you run into problems.
Mark
