Often on ebay I regret bidding too much ,but occasionally I regret stopping too early. These larger Bovoxes are hard to find in good nick, the consolation is I can't imagine my better half would have been too impressed when I walked in the house with speakers as big as these, so maybe it was a good thing after all!
I emailed the seller beforehand about potential foam rot. Though he admitted he didn't really know what he was looking for, he did say there were no obvious signs of deterioration.
