I completed the DTQWT build early this year,
but I've been slow to get the pictures from my phone, finally I have
I finished one speaker first and ended up
listening to that happily for 3 months before finishing the second. I'm
very happy with these DTQWT. Punch, full sounding, natural, no listening
fatigue, love it. :)

good ear, told me she is very very happy with these speakers. It's
always nice to get some compliments for those weekends spent "fiddling"
with speakers! Thanks so much for sharing your designs Troels!
