After study internet i decide to make something nice.
Assumption was to make device not very big, so i decided to make sub with dimensions close to my 80 altones. I had 2 speakers GDN 25\60\1 with new membranes and stiff suspension. Information that I found about them wasn't good - completely un useless for subwoofer. Althought that I've made box for them.
Materials :
Particle board 18mm
1 piece 700x300 front wall, with two holes BR 100mm
1 piece 736x336 rear wall
2 pieces 700x310 side walls
2 pieces 336x310 top and bottom
2 pieces 300x292 middle, with holes 220mm for speakers
Wikol glue
Screws
2 speakers gdn 25\60\1.
Black veneer wood base 3,5m, 50 wide
2 terminals
2 inks BR 100mm diameter and 100mm lengt.
After had put all together, didin't expect revelations, cause i knew that speakers are not good enought for subwoofer. But after had connected, I was very surprise. Bass is nice, glass at the windows starts to vibrate, also I felt strong vibrations at the floor. Subwoofer that i've made perfectly work with 80 altones. All system is powered by pioneer a-656, box is noise proof thanks to 15mm sponge ( not like in picture)
Although i didn't calculate casing capacity, system works very fine.
