Yes, I believe that the Radford Bookshelf had a Celestion HF1300 tweeter, and a special lightweight cone version of the KEF B139 bass unit, and that the KEF Duette had a T15 tweeter (not T27), and the standard B139. I have a pair of Duette's, sort of OK for the small size, but cabinet really needs to be bigger.
