I'm trying to rebuild a pairs of L-150's and I can't find any PR300 passive radiators for sale; I was outbid for a set on Ebay. I was reading a post where I think someone was saying you can make your own with an empty 12" speaker frame.
Has anyone done this? What kind of speaker frames would work best for this application? You'd have to remove the magnets wouldn't you? How can it be done without damaging the frames?
