Hey guys, I am hoping begin to build a subwoofer enclousure for 2 Resonant Engineering RE12's, their entry level subwoofer. I don't even know where to begin, I would prefer to go smaller than larger, but building something 5-6 cubic feet is not out of the question. I am limited to a box width of about 15-16 inches, a depth of about 16-17 inches, and about a 40 inch cap on the height. It will be powered with 300-400 watts.
Specs are as follows:
Electrical Q Value -Qes: 0.42
Mechanical Q Value -Qms: 4.27
Total Speaker Q Value -Qts: 0.38
Free Air Resonance -Fs: 20.0 Hz
Equivalent Compliance -Vas: 182 liters
One-Way, Linear Excursion -Xmax: 12 mm
Efficiency -SPL 1W/1m: 87.3 dB SPL
Effective Piston Area -Sd: 500 cm^2
DC Resistance -Re: 3.2 ohm
Nominal Impedance -Znom: Dual 4 ohm
Thermal Power Handling -Pe: 175 W
Force Factor -Bl: 15.4
So how small could I get away with making this enclosure while still tuning it to 20-25hz, and how long (and wide) should the ports be? Thanks for any input!
