Hello!
I like to build from myself a pair of speakers and after many searches I foud Beta 12 LT-Eminence and G1250-P Audio.
The parameters:
For P A udio-G 1250-
Power Rating : 100 Watts
Nominal Chassis Diameter : 305 mm (12 in)
Nominal Impedance : 8 ohm
Sensitivity (1w/1m) : 99 dB
Magnet Weight : 1.16 Kg (41.05 oz)
Resonant Frequency Fs : 42 Hz
Impedance Re : 6.5 ohm
Electromagnetic Q Qes : 0.39
Mechanical Q Qms : 2.54
Total Q Qts : 0.33
Compliance Equivalent Volume VAS : 97.62 Litr
Surface Area of Cone Sd : 510 cm
Reference Efficiency µo : 1.9 %
Voice Coil Overhang Xmax : 2.5 mm
Diaphragm Mass inc Airload Mms : 51.95 Gram
Bl Product BL : 15.36 TM
Coil Inductance Le : 0.9 mH
For Eminence Beta 12 LT-
Power handling: 225 watts RMS * Voice coil diameter: 2" * Voice coil inductance: 0.83 mH * Impedance: 8 ohms * DC resistance: 7.37 ohms * Frequency range: 45-8,000 Hz * Magnet weight: 38 oz. * Fs: 45 Hz * Vas: 4.81 cu. ft. * Qms: 6.44 * Qes: .55 * Qts: .51 * Xmax: 0.8 mm * Dimensions: Overall Diameter: 12.02", Cutout Diameter: 10.97", Mounting Depth: 4.47".
And the problem is:what driver should I choose for my tube amp???
Come on you guys, help needed,because you know very well the difference of the sound when you put in a box a 12" driver and a 8" driver.
