Hi Troels I have the DTQWT-12s finished. They play low and powerfully, as promised. The tone of the mid/tweeter is awesome, and everything I hoped for. Open and alive, tone is full and satisfying, yet sharp on brass and violins where needed. Gorgeous and exciting sound. I am using the largest 2.7R tweeter resistor. Solo violins never sounded better! Congratulations on a great design. There is not quite enough tweeter for the showoff audiophile recordings like 2L, Chesky, Reference, but for real music it is perfect. I might install a switch to choose the tweeter settings for showing off. :)
