Thank you with such nice designs,and
debugging phase for support. Now,I used spare time of three months to
finish the DIY.The inspired of speaker appearance from ATC, I think this
could have a very strong case. The front panel is a 20mm aluminum,
made it with CNC machines, the surface was sprayed of car paint.
The case production by 25mm MDF, the surface of case paste wood
After the completion, the weight of one
speaker is 30KG, which is really too heavy, but this will be use of the
elimination of this resonance. The speaker and my tube power amplifier
is very matched, I am very satisfied .Thanks again.
Best wishes, Mr. Wang From Deyang
