I lived with a beautiful pair of Dynaudio Contour 5.4's for several years, but my first love was of Tannoy Dual Concentrics. I bought a pair of 12" HPD's, and had them sent from England.
I sold my Dynaudio's, and built a pair of 150 liter bass-reflex speakers that I love much more than the Dynaudio's. I built them very stout at just around 200 lbs. each with out drivers and crossovers. I'll probably be listening to them on the day I leave this existence.
You might want to give them a listen.
Regards,
Dan
