Audio Equipment Calculators / DIY Speaker And Woofer Box Plans

boss tekno pano nman nyong PA na SD18-1700N AT SD18-1700EL na model na walang nkalagay na EBP sa parameter nla?na gngamit ngayun sa mga horn loaded box....tnx godbless..

hindi po pwedeng mawalan ng EBP yan mam, kung may TS parameter ang speaker.,
konocompute po yan, may mga online calculators na po tayo para makuha ang EBP ng isang driver.,
eto sample calculation ng SD18-1700EL
EBP = fs/Qes
Fs = 42hz
Qes = 0.63
EBP = 66

Good for bandpass. pwede na sa w-bin

for SD18-1700N
Fs = 44hz
Qes = 0.39
EBP = 112

good for horn types
