Who's speaker is this?

Not been on here for a while, but after a recent trip to Center Parcs in Cumbria, I spotted these boxes. They are roughly the size of a Q7, or thereabouts. The photo isn't brilliant I know, but they look to have two forward facing drivers, ans a centrally mounted tweeter. There are no manufacturers markings that I could see, so am guessing they are a special projects job from Toa, W&T, or JBL perhaps, or they could just be a home brew box. There are eight altogether, and as far as I know, could have been in since the place was built in 1998.
