Cone Area (Sd) : 467.59 sq. cm
D.C.Coil Resistance (Re) : 3.6 ohm
Electrical Q (Qes) : 0.47
Equivalent Suspension Stiffness (Vas) : 150.31liters(xxxxcu.ft.)
Free Air Resonance (Fs) : 19.64Hz
Frequency Response : 26Hz - 1kHz
Impedance (Nominal) : 4 ohm
Mechanical Q (Qms) : 10.71
Total Loudspeaker Q (Qts) : 0.45
These are some of the specs of the Alpine 15" Type R sub for car audio. I can get these at a really good price. The only thing it doesnt list is Xmax and I'm sure I could call the company and find out.
Then here is another sub, the MTX Thunder 8000 15" also a car sub.
Fs 24.6hz
Vas 145.5 L
Qts .37
Qes .40
Qms 5.69
Xmax 12.5mm
D 13.267
Spl 89.3
Im deciding between these two and the Tempest driver for a ported or sealed cube to go under my svs 20-39. Ideas??
