[QUOTE="LuckyPiston13, post: 5526257, member: 576616"] Can't believe I forgot to put the size. They are 12", 500w RMS, 1000 peak. The following specs are from the Orion website: Fs (free-air resonance, Hz) 26.15 Vas (equivalent compliance, cu. ft.) 2.095 Vas (equivalent compliance, liters) 59.33 Qms (Q, mechanical) 4.66 Qes (Q, electrical) 0.48 Qts (total driver Q) 0.44 Re (DC resistance, ohms) 6.77 Z (nominal impedance, ohms) 2.8 Le (inductance, mh) 2.57 Efficiency (1W @ 1M, dB) 85.32 Xmax (one way linear excursion, in.) 0.67 Xmax (one way linear excursion, mm) 17.19 Pe (continuous power handling, watts) 500 Peak power handling (music, watts) 1000 Mms (total moving mass, grams) 216.26 Cms (mechanical compliance, mm/N) 171.32 Bl (motor strength, Tesla-M) 22.32 Sd (effective radiating area, sq. m.) 0.05 Sd (effective radiating area, sq.in.) 76.88 Frequency range (Hz) 30-2.5k Energy Bandwidth Product (EBP) 54.23 Model Number P12D4 Mounting hole diameter (inches) 10.95 Mounting depth (inches *) 5.25 Basket diameter (inches) 12.45 Model Number P12D4 Typical sealed enclosure (cu. ft.) 1 SPL sealed enclosure (cu. ft.) 0.7 Low Qtc sealed enclosure (cu. ft.) 2.5 Vented enclosure (cu. ft.) 2 Port tuning frequency (Hz) 40hz Port diameter (inside, in.) 4 Equivalent square port (in.) 3.54x3.54 Port length (in.) 7.44 [/QUOTE]
