Great post,
Just to mention I did see a large group of Celestion club speakers on sale on e-Bay.
The brand as I said was Celestion and there were about 20 speakers from a night club that were being auctioned off about a month ago. This is a trusted brand in England and the model was for pro-instalations. I bet you could pick up some of these for real cheap used from a club set up. Also check other brands for similar used items. Remember this is e-Bay and sometimes things are stolen at such a great price it is a crime not to atleast check out your options.'
Good Luck
