3in midrange buyout

[BHTX]

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.

both speakers are measured at listening position ~12ft away
next step is to add 6db high frequencies roll off, starting at 2k

[MisterTwister]

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.
