parallel vs series wiring

Sorry I thought this is where I ask the vendor a question.

1) Not quite sure what you're asking, but all speakers change impedances at different frequencies.
2) Not sure, but why does that really matter? All that really matters is the phase of the woofer cone relative to your other speakers.

Edit: How'd you manage to get this in the SSA section? @pro\-rabbit ; @audioholic ;

Lets say i have an amp with peak power at 2ohms and i want to buy 2 12" subs.. is it better to get dual .5ohm and run series or single 4ohm and run parallel.

Here's what a friend sent me regarding putting multiple subwoofers in one chamber...

..."parallel wiring is to be prefered in general.Impedance peaks, even at frequencies higher than fs,*correlate with high voice coil velocity due to resonant conditions.

Parallel wiring will tend to balance voice coil velocity betweendrivers, when resonance peaks are differing due to tolerances,which is normally the case. The resonating driver simply getsless current than its non resonating neighbour.

In the series circuit current through all drivers is the same,and the resonating driver will see higher voltage at his clampsthan his non resonating neighbours, which tends to make thingsworse, because power is always distributed to the driver whichbehaves worst at a certain frequency"...

yeah, how did you get this in here. next time post your similar questions in threads that are made for such instead of vendors forums
