Hey everyone first time poster. I've had my Axioms about 6-7 months, I have two pairs of M2's and the VP150, my sub is a SVS 25-31 PCi. Very happy with the system but, I am not satisfied with the mid bass "slam" or "punchyness". I replaced some older Boston Acoustics VR1 towers and CR series speakers with the Axioms the lower bass is good and mids and highs but there is just something missing. So just wondering is going with the a smaller sub like EP125 or M50's or M60's would help. My feq cutoff is 60hrz for the M2s and the 150, sub cut off is 100hrz. Thanks.
