I just had my Alon IV woofers rebuilt by Miller Sound. One woofer was really bad and was scraping. They came back as good if not better than new. I got the full treatment.
My Alon's are now blowing me away, best upgrade I could ever treat myself too. Bass is tight, defined, and deep.
I also own Dahlquist DQ10's that I've toyed with getting rebuilt but have not yet done so. Purchased them new in 1978. I have a pair of Radio Shack woofers in them just to see what would happen. They are still nice but will fatigue you.
I almost purchased a pair of DQ20i's off Craigs List in Nov 2012 but the owner said one woofer kept cutting in and out when moved. I own enough old speakers and did not feel like messing with another rebuild.
