Vifa M10MD39 Midrange drivers USED

This Vifa model was used as an upgrade for the original ACI G2 cabinets from the original Seas 10F-M mids.   This pair is from a set of ACI G2 cabinets.  They are USED.

These are nominally 4" drivers, (104mm) with magnesium frames, and butyl surrounds.  

Here is some data from VIfa:

• Long term max power [W] -
• Operating power [W] 6.3
• Sensitivity [dB] 88
• Frequency range [kHz] 0.3-8
• Free air resonance [Hz] 110
• Voice coil diameter [mm] 20
• Voice coil height [mm] 5.3
• Air gap height [mm] 4
• Voice coil inductance [mH] -
• Eff. diaphragm Area [cm²] 37
• Moving mass [g] 2.9
• Magnet weight [g]/[oz] 210/7.4
• Force factor [Bl] 4.1
