|Gooood morning Mr. Gravesen!!
Here I am, after
10 months, in the end my pair of GROWN UP DTQWT
extended (with a pair of 12 inches eminence
deltalite) are ready and are currently breaking in. At
this stage I will not give any listening impression since
the speakers have played only a couple of hours. All I
can say is that they have a really huge sound
the symphonic music is really amazing with them
and they are really efficient.
the pictures can explain the way I built them up. My aim
was to build a case virtually made with no
panels so that the vibrations generated by the
loudspeakers can see only a huge (more than
100 kilos) mass.
the case while the speakers are playing you can barely
feel vibrations, so I think it worked.
cant help finishing the breaking in and enjoy my CD
collection as never before!!
to you I can enjoy a really HI END speakers at a very
reasonable price and in addition I really enjoyed its

afternoon, Mr. Pantaleone!
Quite frankly, I feel envious of what I see here! I'd
like to hear the 12 inch version and too bad you don't
live next door. I had never dreamed of someone making
cabs like this and I would need a cousin dealing with
Baltic Birch to make it happen.
Thanks a lot for reporting and I hope the immediate
impressions will last. You may later try out recent
crossover developments that will throw an even deeper
sound stage. Check out: http://www.troelsgravesen.dk/DTQWT_tweaks.htm
(The speakers here were built based on this draft file: http://www.troelsgravesen.dk/DTQWT-12.htm)

Im very happy that you liked my job!
The final amps are the mono Mastersound Monoblock 845:http://www.mastersoundsas.it (parallel single ended of 2
845 and 50 watts RMS).
The pre amp is the SA 5000 up-graded at the maximum level
( except for the phono stage) by his designer Mike
During the week I work in Rome and I stay home during the
week end, so I cant wait to go home Friday and
continue to break in the speakers and listen my favourite
I hope that the building process is clear: I realized
(with a CNC machine I think this is the right
name) various lateral sections of the speakers and I
stacked them one on another under a press machine with 20
tons of weight and glued them together with vinyl glue.
As visible in the pictures I made the central bracing by
modification of the section itself.
My best regards.

Good afternoon Troels
As requested I forward you a picture of the b-side
of the speakers. The more they play the more their sound
gets excellent!! Regards, FERRAIOLI Pantaleone Leo
