I will tell you my story. I had a beautiful pair of Rosewood Dynaudio Contour 5.4 speakers I thought I'd keep until I died. But, I couldn't get over the feeling that I had unfinished business with Tannoy. I sold my Dynaudios, and set about building a pair Tannoys, I used HPD 315 drivers and crossovers (12" Dual Concentric).
I came out with a pair of speakers that are 150 liters, 48" H X 17" W X 20" D. Each cabinet weighs 192lbs. sans speakers and crossovers. They are bass reflex. The Tannoys beat the the bejeesus out of the Dynaudio's.
So, I suggest you try listening to some Tannoys before you decide.
Best regards,
Dan
