I am not speaking of 0/180 degrees,as a subwwoofer filter/crossover.I have heard MIT and the filtering/Band Pass filters do effect the frequency spectrum/sound.Changing out to a piece of wire which does not try to do such sophisticated spectrum/frequency shaping may or may not be an eye opener.
The passive filtering may give a smoother top-end or fuller midrange/midbass,but I can't see how its' attack/sustain/decay characteristics would be better than a straight wire configuration,as a passive component in-line will contribute its' own signature.If the source component,pre or power amplification can't provide what is needed,then fixing it with a filtering network after-the-fact is much like a bandaid.You would need to know what you are trying to correct and not issue a "blanket" filter.As the filter for one system would not be applicable to another.
I don't know that I can explain this differently.It is something that must be experienced.Every system has its' own contribution to the perceived sound.Whether that is to the listeners' preference is another issue and its' adherence to the source yet another.
My two-cents:try it or ignore it.
