A few Scalford Shows ago I seem to recall Simon sq12344etc sharing a dem room with a guy who had pair of speakers - Tannoy drivers in a tall enclosure (1.5m-ish?) shaped kind of like you describe, Paul. Quite probably the best Tannoy-based design I have heard.

Maybe worth dropping Simon a line to see if he knows owt about it or can give you a contact?
Thanks Jerry. Perhaps worth a look. I've designed the cabinets to extract the best performance from the 315's, at least on paper/computer! I have made a few changes since I started, as further modelling and speaking with a friend who will be helping me with the build (he has a great deal of cabinetry experience) has refined the design. We will either experiment with a home brewed vacuum forming machine to form curved ply sheets to be laminated for side panels, or I'll make the shape more a conventional box but use internal sloping baffle boards to prevent standing waves formation. Either way, the front baffle board design has been extended slightly to 550mm to reduce baffle-step losses.
