Just tested, perfectly woorking pair of this excellent sounding drivers.
They have beautiful coulourfull midrange presentation. No hint of dryness. Reminds me on Jantzen 8008hqm driver with less sensitivity and lower bass.
17 cm bass-midrange driver with paper cone.
The basket is made of die-cast.
frequency range = 38-4000 Hz
resonance frequency fs = 37 Hz
impedance R = 8 Ohm
sound pressure level SPL = 88,8 dB (2,83V; 1m)
DC resistance Re = 6,5 Ohm
force factor BL = 7,9 N/A
effective piston radiating area Sd = 131 cm2
effective mechanical mass incl. air load mms = 15,3 g
equivalent volume of compliance Vas = 29,9 l
total Q factor Qts = 0,36 (Qms=9,5, Qes=0,37)
voice coil diameter = 39 mm
maximum peak linear excursion vibration xlin = +/- 5,5 mm
mounting diameter d = 153 mm
overall diameter d = 182 mm
mounting depth (not countersunk) t = 88 mm
Price more than 50% discount as new ones ...199€ for pair.
