I have a JBL 12" car subwoofer (Double coil) with a 350 watt plate amp currently in a 17' x17" x19" cabinet and it works ok , but I want to build a better box.
Using Win ISD program, it came up with a 31 x 18 x13 box for a 4th order bandbass design. Using that design the specs read FLAT 20hz to 50hz -6db all the way (My amp has enough gain to bring the volume up)then a nice roll off.
But looking at that design, the woofer is inside the box and only having a 4" port. Where is the output? To me that doesnt make sense, like it will only creat Boom not reproduce music. Am i correct? Can i use this design for music (Not HT) or should i just stick with a vented design open woofer cabinet
Specs:
12"
VAS:3.45
QMS:7.14
Qes:.47
QTS:.44
TM: 7.71
FS:23.50
Sensitivity 93db
Or should i not wast my time and buy a home subwoofer
Thanks
Bob
