I know this has probably been discussed here before; but I need some help with
building a subwoofer box. Currently I have a JL 13w1v2 subwoofer in a store-
bought sealed box. The bass it puts out is pretty good for a low power sub, but
I'm looking to be able to hit some lower frequencies.
I know the basics from doing some research on the net. Using 5/8-1'' MDF,
bracing, how to seal the box etc., but I having trouble understanding how to
actually port the box and to how large the box, and port would have to be. Below are the specs of my subwoofer:
Free Air Resonance (Fs): 20.9
Electrical “Q” (Qes): 0.4060
Mechanical “Q” (Qms): 6.9366
Total Speaker “Q” (Qts): 0.3840
Equivalent Compliance (Vas): 6.131 cu. ft. / 173.51 liters
One-Way, Linear Excursion (Xmax)*: 0.475 in. / 12.1 mm
Reference Efficiency (no): 0.375%
Efficiency (1W/1m)**: 87.71 dB SPL
Effective Piston Area (Sd): 105.774 sq. in. / 0.0682 sq. m.
DC Resistance (Re): 4.114 ohm
Nominal Impedance (Znom): 4 ohm
Thermal Power Handling (Pt): 200W
Driver Displacement: 0.05 cu. ft. / 1.42 liters
Net Weight: 11.21 lbs. / 5.08 kg
Here is also a link to the JL website if you would need more info.: JL Audio Products: Subwoofers / 13W1v2
The car this is going into is a 2001 Chevrolet Monte Carlo if that gives you any idea of the trunk space I have. TIA for all replies.
