ok, I got them connected 26 in a row and back to back.
so there are 52 speakers per side.
see attached wiring diagram I'm going to use.
each row should be ~12.7 ohm and then wired in parallel with back row. for total impedance around 6-7 ohm. (these are 4ohm drivers)
any suggestions for a better wiring?
I used this info for reference.

finishing up second pair. surprisingly, they don't seem to be very sensitive
and there is too much tssss sound. i will take measurements after hanging second piece of array.

you'll need to measure them in your enclosure, in your room.
besides with line array it's even more complicated.
I'm going to measure mine at a listening distance, about 12ft away.
I still can measure one driver on a large baffle if you want.

danny1974,
here is FR 3in away from baffle on axis.
and picture of baffle (couldn't find a better one)
BHTX, those are very nice. cast frame, 4in voice coil,
extended pole piece (at least brochure says so)
smooth impedance curve, huge magnet.
I have not had a chance to play them loud though.
I plan to use them 200-50hz.

Of course I'm late on the scene, but it may be useful to somebody. Any time you want to use multiple drivers, the easiest wiring comes from square numbers(4,9,16,25...) The series/parallel configuration jumps right at you. If you want to use power tapering to pull the image to the center of the array, then the impedance games begin. Anyone who hasn't read Jim Griffin's line array white paper is missing out.
red curve is array + Pyle woofers
blue curve is addition of two dayton 15HF subs in U-frames.
for crossover midiland ads4000 is used. array is set as "small" speakers.
I added simple circuit to pad down high frequencies.
Sound is much better, but still is too bright for my taste, I need to attenuate that 3-5khz hump.
