  1. Hello I am thinking of making a LaScala two ways with a Faital-pro HF200-8 +TD460N or a Faital-pro HF140-8+LTH142, combined with this Beyma 12BR70-8 in the bass bin ! OK it is just a 12", if it has to be scaled down, lets do it. Could this be done ? I have no simulation tools nor talent for doing it. TECHNICAL SPECIFICATIONS Beyma 12BR70-8 Power capacity 125 W RMS Nominal diameter 300 mm 12 in Nominal impedance 8 ohm Minimum impedance 6.6 ohm Program power 250 W Sensitivity 93 dB 1 W @ 1m @ 2Π Frequency range 25-4000 Hz Recommended enclosure volume 50 / 120 l 1.77 / 4.24 ft³ Voice coil diameter 52 mm 2 in BL factor 12.1 N/A Moving mass 0.074 Winding length 19 mm Air gap height 7 mm Xdamage pp 25 mm THIELE SMALL PARAMETERS Fs 31 Hz Re 5.6 ohm Qms 4.44 Qes 0.56 Qts 0.50 Vas 142 l Cms 345 µm / N Rms 3.3 kg / s Efficiency % 0.76 Sd 0.054 m² Xmax 8 mm Vd 340 cm³ Le @1 kHz 0.85 mH CONSTRUCTIVE DETAILS Net weight 3.6 kg 7.92 lb Total weight 4.1 kg 9.04 lb Magnet Ferrite Thanks
  2. My Kg3-2 woofers are still in working condition but I believe the foam is going to give way as it is getting slightly powdery. I have looked on the net and didn't find an original replacement, so I am wondering if anybody has use the service of Orange County Speaker repair for these particular woofers K1002K and KD11. Thanks
