D-Man; Look at Hurdy Gurdy's post in the Speaker Forum. He has an Open Baffle speaker using that driver modified that he likes a lot. Will it sound like a Tannoy??? It will sound good I don't know about replicating a Tannoy. But I agree the Tannoy is a very good speaker. So; what is it you like so much about them? If you can express that maybe you can find what you need.
