Should speakers and subs be on the same horizontal plane? I found that when my
speakers were behind the console (which was on the same plane as the sub which
is also towards the corner of the room behind the console) kicking in the sub
was like WOW... now that my speakers are back on the console top (which sounds
better to me), the woofer doesn't kick in with as much umph. Any tips on
placement of the woofer?

Technically, subwoofers should be closest, then woofers, then tweeters,
since the larger the speaker, the slower it reacts etc. Your problem is
probably more a result of the monitors being closer and louder than their
previous position, making the sub less pronounced by comparison. Start by
turning the sub up, next hit google for speaker placement tips because
there's too many issues to address in a ng post.

Remember your goal is consistency, not the best sound, and no matter what
you're going to have to learn to compensate for changes in your monitor
arrangement. You're mixing not partying.

You may want to check the polarity setting on the subwoofer.

The mid/high box should be right on top of the subwoofer with the voice coils
time aligned. Otherwise the lows arrive out of phase with everything else. This
is what time alignment is all about.

Not necessarily.

The classic means for optimizing the subwoofer's position is to put the sub
where you sit when you listen, and then move around the room listening for
the best bass. Then relocate the sub at the location where you hear the best
bass.

I understand and agree, but need a clarification. "time alignment" is
nothing more than getting the radiators (cones, domes, etc.) to oscillate
across a single plane, right? Isn't it nothing more than physical
alignment?

If there is no phase shift in the crossovers, all you need is physical
alignment so all drivers are in one plane.

When you physically align the drivers, the *sound* is time aligned.

If there is phase shift in the crossovers, the drivers need to be moved
to compensate for that. Unfortunately they can only be moved to compensate
for it on a single axis.

In the case of the sub, there will also be substantial phase shift due to
the interaction with the room, which will affect where it needs to be
(and/or how you set the all-pass network in the crossover).

there's a great how-to on sub placement at www.digido.com
