Thanks, Tony. That might work pretty well. I'll look around for a product I like.
Andy, thanks again for the suggestion. They will work very well for the intended use.
Actually, I found a US store that deals with Wharfedale products. They didn't have any of these panels in stock, but they were able to order it for me from the one US distributor and have them shipped to me directly. Only $59 each, which is better then I would have paid for on the exchange rate at Canford.
Actually, we would have bought through Canford, and we were ready to, but the shipping would have turned out to be around 130 pounds!! It of course wasn't due to the weight, but the size was quite large.
So, thanks again! I install the speakers tomorrow
