hello,

i recently bought a zpa0.3 after my zx600 died.
i connected my rsdc12.2 in 4 ohm and it plays realy well.
but what is the best way to go, is it better to wire the sub in to 1 ohm, or into 4 ohm?
on the rsdc manual it says a sensitivety of 94.2 db/watt if wired parallel, so into 1 ohm, but will the sensitivety be bigger or smaller when wired in series, into 4 ohm's or will ther be no difference?
thanks in advance!

Generally "sensitivity" is usually another term for "efficiency", which has to do with the materials used, motor design, magnetic gap strength, spider & surround design, and how easy/hard it is to flex the woofer under specific amounts of power.

Final impedance should have no affect on this.


Although I'd run it at 1ohm in your case, letting loose the power you will want.

Run it at 4 ohms. Same power, same efficiency (the 2.83v efficiency ratings need to be converted to 1w/1m, since impedance affects the results). At 4 ohms it would probably sound better due to a higher damping factor, and it wouldn't require the amp to switch into high current mode.
