I am a fan of VA speakers and I would say, do not use "any old" midwoofer to fix your problem. I have seen the Bach Grand woofer for sale on Ebay many times. It's not there now -- but I would keep checking.
If you don't have any luck, you can also email Vienna Acoustics directly, in Vienna. I've done that many times and bought replacement woofers. I bet they still have the one you need.
