I think you should make them I got a reply back from ionic dynamics, they offered me a discount of 15% if i ordered 6 and $70 to post the lot. Ive sent an email asking if they do a RHD version, but i doubt it.
There was a guy on eBay that sells the same thing...I send him a msg about a RHD version & he said that he doesn't make them, but if I supplied him with a stock RHD surround, he could easily make a RHD version. Can't remember the seller ID on eBay, but if you have a look, it should still be there. Hope that helps. Abraham
