I have a Music Man 212-HD 130(one with a tube phase inverter),and was wondering about an extension speaker. The speakers that are in it =3.5(4)Ohms(the originals by the way) and so the impedance switch is set to the 4 Ohm setting, but what about adding an extension cabinet. If if the impedance is already at the recomended minimum what impedance extension cabinet is used. The only
thing posible would be a 16 Ohm cabinet, which would put the impedance close to 6 Ohms, but the when the power is split between them the orginals would recive over twice the power that the extension cabinet, acording to Ohms Law. while not to much of an audilble differance, it does'nt make it very eficient, in fact I've tried it and with out very eficient extension speakers it rob's a little power, defeting itself. I was if you could make some suggestions of why this was done this way.
