I have YEARS of experience playing with equalizers.
NOT to use them permanently, but to see what peaks and dips in different frequencies sounds like.

I have noticed that a thinness in the 100 to 600 hz range makes speakers image all over the place, and provide a SUPER detailed sound.
Unfortunately, it don't sound like music.
I hear a HOLE in the VMPS RM 40's.
I see a flawed speaker design.

To FIX the VMPS RM 40's, here is what I WAS going to do.

I was going to use two different 10 inch woofers to fit the "alignment", if you want to call it that, LOL
Then, I was gonna use a Rane 24 db electric crossover.

The vertical separation on the RM 40's two 10 inch woofers IS a PROBLEM.

I think we calculated comb filtering above 250 hz ?

I was gonna try experimenting with the crossover frequency, and steep slopes.

I WAS talking about this when I got banned from VMPS Forums.
