After I received the non polarized electrolytics I replaced them on the crossover. I had to order extra 50uf capacitors as Parts Express did not carry 25uf caps. I put 2 - 50uf caps in series to get 25uf.
To make a good seal around the speakers I picked up some weather stripping. I wanted a good seal since this is an acoustic suspension system.
I used a hair dryer and a vacuum to pop out the pushed in "fried egg" tweeter. One will not pop out and I will have to work on it.
I put everything together and hooked it up to my tube amps. It sound really nice.
