[QUOTE="johnnyvolcom5, post: 5547516, member: 605736"] Can someone explain these specs in a simple matter....like what they mean and what you should be looking for when picking out subs. EG FS= 25.0 HZ......FS is.......and a good range is 20-30 (just an example****). try to keep it as simple as possible...thanks. Free Air Resonance (Fs): 25.0 Hz Electrical “Q” (Qes): 0.480 Mechanical “Q” (Qms): 7.100 Total Speaker “Q” (Qts): 0.450 Equivalent Compliance (Vas): 2.82 cu. ft. / 79.9 liters One-Way, Linear Excursion (Xmax)*: 0.65 in. / 16.5 mm Reference Efficiency (no): 0.250% Efficiency (1W/1m)**: 85.9 dB SPL Effective Piston Area (Sd): 77.8 sq. in. / 0.0502 sq. m. DC Resistance (Re): 6.75 ohm*** Nominal Impedance (Znom): Dual 4 ohm Thermal Power Handling (Pt): 600W Driver Displacement: 0.090 cu. ft. / 2.5 liters Net Weight: 19.4 lbs. / 8.8 kg [/QUOTE]
