Hello NeverHappy,

Hope you are well. Your frequency range below 95Hz is not in your +/-3db range of the VP100. I would switch to a 100Hz crossover with your setup. Frequencies below 95Hz will drop in db depending on how quickly the VP100 trails off in the low end. You will still get sound down to about 65Hz, but it will not be as loud as what you get from 95Hz on up. Would be nice to see a graph of the frequency response of the VP100 and VP150, but I have not been able to find one.

Here is the frequency response chart for the M2i from the Soundstage review.

and here is the one for the M3Ti that you own.

both cross over at 80Hz perfectly.

As to using one M3Ti, I tried one M2i and found it limited by itself, adding the second M2i disperses the center channel much better than one. I am quite happy with what I am hearing.

Later,
