SoOoOo thats what i am going to do. i already had the box started with this design. but for some reason i can't get subwoofertools.com to work for me and i cant uploud anything to figure Hz cause i have vista and its for XP and like win 98 and stuff. so can anyone tweek this design so it will be at 35Hz and not 31Hz? please and thank u! this is the sub BX12D2 12-Inch 2-Ohm DVC Driver Theile & Small Parameters: WRMS = 600-Watts U = 2-Ohm + 2-Ohm Fs = 31.05 Hz Qts = 0.433 Vas = 47.39 Liters Xmax = 15mm SPL = 95.77dB @ 2.83v this is the design i have now http://www.putfile.com/pic.php?img=6600214 |
