Hi.
Kind of a multiple part question here:
I have several 2" full range drivers that I wish to wire in a vertical array. On each side I have four 4 ohm drivers and eight (otherwise identical) 8ohm drivers. I was hoping to locate the 4 ohm drivers at the center of the array(flanking a small tweeter used to extend the highs).
I was wondering,
1. Say I wired two sets of two 4ohm (4+4 series equal 8ohms) &
(4+4 series equal 8ohms ) in series/parallel with two sets of the 8ohm
(8+8//8+8 series/parallel equal 8ohms) & (8+8//8+8 series/parallel equal 8ohms), how would putting the 4+4 ohm set in parallel with the 8+8//8+8 differ from putting the two 4+4ohm sets in parallel with one another (or no difference), when making the series parallel array?
2. I'm also interested in the sensitivity increase overall, and
3. Would the 4 ohm drivers be louder than the 8ohms when wired this way?
Thanks in advance for any advice or guidance here.

what overall impedance are you shooting for?
and it's a little unclear as to the overall number of drivers....is it 8?
are you trying to create an amplitude shaded array?

Yes.
Twelve drivers, wired as above to get 8ohms total.
Please explain how to arrange as a shaded array, and will
any drivers be louder than others.
Note that all drivers have same sensitivity 82db/W/M
Thanks

due to ohm's law the lower impedance drivers will be louder and so as long as they are located in the middle of the array you wind up with an amplitude shaded array but c to c spacing still governs the highest frequency at which comb filtering starts to come to bear.
