Hey Uncle,
I would try sticking with the x-overs in the 4000x as much as possible and
not your amps. These x-overs are active and they make a more precise slope
and cut off than your amps. Also, since they are in the digital range and
the x-over is coming before your amps, this would let you make the most of
your amps power and your dynamic range will be as best as possible.
With a two way system, setting the x-overs will not be that difficult due to
having fewer GOOD options. If I were you, I would place a much musical
information as you can to one speaker on the left and to one on the right.
(If the midrange was in the kickpanel, for instance, send as much
information to this speaker as possible, and send the remaining information
to the tweeter. The reason for this is that in order to make the best
stereo image as possible, the sound needs to APPEAR as though it is coming
from one centralized location on the left as well as on the right. If half
your musical information is in the midrange and the other half is in your
tweeter (say the x-over is at 1k) then your center image and overall sound
will not be as sharp, due to the fact that you will have competing sound
source locations (2 on left and two on the right) as well as due to other
more in depth factors. Consequently, you image will not be as sharp as it
could be.
With the 4000x, I would x-over your midrange and tweeter at 6k, thus
maximizing the amount of information going to the midrange. The midrange is
the single most important speaker in the system, at least for SQ freaks, and
if you have a 4000x , most likely that is the reason you do...for SQ. If
your tweeter is located very close to your midrange (say about a foot or
less) then I would place the slope at 72/db. If your 2 way setup is more
seperated (for instance, the tweets are in the dash, while the midrange is
in the floor or door), then I would go with the 24/db, since this slope is
more natural sounding and would role off in a more forigiving way than a
sharper slope would. Otherwise, it is easy into phase coherance, despite
having some control with time delay.
I don't know if you have a sub or not, or intend to grow your set up a three
or four way system, but it would be an obvious good idea. I'm sure your
intending to do this.
Hope I've been somewhat helpful.
