I have an old, surplus-to-requirement, 15" McKenzie speaker. I'm guessing it's from the 1980's or early 1990's, and it's rated at 200w and of 8ohms impedance. The chassis is cast alloy.
It will be posted in a proper speaker carton, but if you want to collect I'll knock off the price of the postage and include a cup of tea.
£40 posted.
Thanks,
