Way back when I tried to combine multiple bars and got burned by different series I had to unload the bars and locally wasn't an option because I had too many. I shipped them like a twinsonic meaning I just pretended the highest and deepest part (the speaker) was the actual dimension of the bar. The boxes were big but not really bigger than an XL9000 or Twinsonic, there are just voids to pad and fill. In today's shipping market I would only ship a super rare one for super rare $$$. You will probably spend $200 in shipping and packing if not more. As far as parting them out, I hate to see that but it's probably the way to cheaply sell them, especially on eBay.
I did not know about Speedee, thanks. Otherwise just trying to avoid so much wasted space!
There is no good way to get around the wasted space. I did have one shipped to me that wasn't packed at all, just wrapped in plastic. It wasn't damaged but I didn't know that the person was doing it that way and wouldn't try that again.
