A long overdue update, as I have been distracted by a number of things the past few months. I was able to get the speaker to an amp/speaker specialist who tested all of the components for me, and he confirmed that the only issues he could find were with the drivers themselves, one is frozen and the other has a burnt speaker coil. It looks like i am going to be in the market to buy some replacements once again.
Don't cry. Hopefully, you'll get the RM30C speakers up and running again.
Next, don't trash the suspect woofers. I'd send them out for repair first. Even if you can find replacement woofers, I'd still get the original woofers fixed, to keep as spares. So, contact Bill LeGall at Millersound. Bill is probably the top speaker repair guy in the country. Plus, Bill's repair rates are very reasonable.http://www.millersound.net/
As far as finding new woofers, contact Patrick Malaga. Patrick purchased all of the old VMPS stock. He might have parts? PM him through AC. Patrick also posts VMPS parts for sale ad's on the San Fransisco Craigs List. Here's one of his ad's. PM him through CL too. He might respond to that faster.https://sfbay.craigslist.org/eby/ele/d/vmps-new-subwoofers/6472360965.html
Also, Misco still shows the LLC62W-8A mega-woofer on their site. You should be able to order direct through them.http://www.miscospeakers.com/speakers/LLC62W-8A
And one other thing. Once you get the center speaker up and running again; set it to Small. Less stress on it that way.
