yes they had a full range driver, but were also available in Kit form.. I had some mounted in side 2 concrete pipes, about 10" diameter and over 3 feet high! With an acoustic filter about 2/3 of the way down, and a vented plinth at the bottom.... Not the best in the world really!!
From the look of them, I think these were home-built...a pair with the pukka Wharfedale badges was sold on eBay a couple of months ago & the construction/detailing/finish looks significantly different (more professional).
