I don't have a chart like the one you guys are looking for...

Since I bought the plans...

This is what Bill says in the plans.

Quote:

Impedance
   
   LAB drivers have a nominal impedance of 6 ohms, but the mass of air in the horn adds about 2 ohms of acoustic impedance, giving a nominal 8 ohm load. In a 2x12 a pair of LAB 12s wired in parallel will have a nominal 4 ohm load, a pair in series a nominal 16 ohm load.



Thanks Miguel, that's exactly what we were expecting. Thank you for confirming that.


Take care,
Phil
