trying to work with this cabinet at present JBL 4638 twin 15"
now I have a couple of previous posts regards this. (jbl 4435 knock off)
But what i am looking into is, as i have the cabinet vertically unlike horizontally (jbl 4435)
lower driver crossed around from 20---300hz
next driver 20---1500hhz plus
there is a 600hz null with this cabinet center-center spacing.
the waveguides I have are the jbl/pyle 612 econowave now previous advice was that waveguide could not go low enough.
so i had a brainfart
the KEF concord back in its day
the nexo to this day
also this post on diyaudio that went dead https://www.google.co.uk/url?sa=t&r...d.html&usg=AFQjCNH7OkEBLUoPxkL1Ai52FoFbucultA
with good input from bjorno a member on here who provided this tech spec (could someone put his results/findings into plain text please)[IMGDEAD]http://i66.tinypic.com/2egff40.jpg[/IMGDEAD]
here is some drawings of what i was thinking (DSP INVOLVED REGARDS DELAY XOVER)

basicly having the compression driver and waveguide mounted on the driver but protuding quite a bit forward from the baffle.
if i have not put it into words right please say
