Hi all I'm about to build my first box as the box I bought i've found out is a bit to small at 28L. The sub I've got is a JBL GT3-12 which i've found on the net should have either a 40L sealed or 50L ported but thought I would ask you guy's the spec's for the sub are as follows
JBL GT3-12 12"
RMS Power Handling:225W
Peak Power:1800W
Voice-Coil Diameter:50mm
Mounting Depth:155mm
Qes:0.6
Qms:5.53
Qts:0.54
Vas:100.45 ltr
Fs:28Hz
Pe:225watt rms
Frequency Response:35Hz - 3kHz
Sensitivity:89dB
Impedance:4 Ohms
At the minute I have a wedge shaped box which fits perfectly against the back seat so would like the new box to be of the same shape. The room I have for the box to take up is 41" wide, 16.5" high & 12-13.3" depth can put up the size of the box I have at the minute if it helps Ideally I would like a ported box if it's possible but have know idea on size of port(s) to use. I listen mainly to dance music & rock if that helps.
I would be most grateful with any help & possible design with measurement if you can
Many thank
