I have had a pair of Lansing Valencia 846b forever. In storage for the last 3 years. I need to get these things rawkin again. I'm missing one driver, diaphram, the whole assembly, and the other one doesn't work. I saw auctions for these for $450 and more that I really don't want to spend.

What can I bolt up to these horns that will get me back in order?

TIA
