The worst job was to put spatula and grinding to put veneer. Easiest was to screw conventers and putting column cables into amplituner
Construction seems to be very conservative, but works really good. Sound is beautiful you can hear all, even minute details. I compare it with bigger systems like fenix – for me and for others listeners my construction is much better. Of course they are missing low tones, but don’t worry, I’m going to make subwoofer for them.
Converters used:
Tesla ARN 150-05-08
Tonsil GDW 9/60/4
Tonsil GDWK 8,5/50/1
Here’s branch, I believe that diagram is the easiest way to see anything. There is complete description of all elements.
GDWK plugged in antyphase.
All device in veneer cover, painted 3 times by semi dull lacquer. Before each painted, I had sanded. First by large grain sandpaper, next smaller till 380 or 420 (I’m not sure). All stand on bolts and is tuned to about 40Hz. Capacity for ARN is about 18l. There is special pod for “up and down”. They consist soundproof foam 20mm. Box glued by wikol and tight by screws. Wikol mixed with wood dust – lube 3 times. Wire inside is 2x2,5mm2, or 2x3mm2 again problems with memory.
At one picture you might see that cutter under GDWK is damaged. but it’s only at the picture. Branch was designed by one of my friends.
Device is powered by Yamaha rx-v440. I’m going to built subwoofer with 25cm speaker. I’m thinking of tonsil gdn 25/80/1 or STX GDN-27-450-8-SC. Sound system will work in 16m2 room, sometimes, at the party in 45m2. I consist amplifier with big power, about 150-200W
