Realistic Minimus 1 speaker needs new woofer

[vortalexfan]

Hello everyone, I had found a couple of years ago at Goodwill a set of Realistic Minumus 1 Speakers and I was using those as my work bench test speakers because of their small compact size.

I accidentally blew out the woofer on one of them while I was working on a stereo receiver that had a bad amplifier channel in it that I thought I had fixed and it turned out it wasn't and it passed DC into the woofer and blew out the speaker.

Fortunately the tweeter was unharmed strangely enough, just the woofer was damaged, and its an oddball size of 4 1/2" square and Parts Express doesn't have anything in stock that's in my price range, and I can't think of anywhere else to look.

Anyone know where else I could look for the speaker I need?

Any help would be appreciated in this matter.
