Today I worked on one of the AR-5's.  I decided to put the speaker together that the woofer that I refoamed only lived in.  I've yet to measure the Fs of the woofer I replaced the spider on, and I want to do that before I put that woofer back in the cabinet. I bought a pair of the HiVi Q1R tweeters, along with a pair of 0.05mh inductors to place in parallel with the tweeters.  I'm using those tweeters for now, the original pair will be going to @Chris1this1.  I worked on one speaker today,
