Will a sub woofer mess up my tone and phase aligned speakers

Hi, I posted recently about my vandersteen 1ci 's. Someone suggested I add a sub woofer.  Well I've found a nice 2nd hand Martin logan grotto (not i) (comments welcome).

My question is: will the addition of a 3rd party sub work at cross purposes to the time & phase alignment of my 1ci 's?

I used to have 1Cs, and I added a pair of 2Wq subs. They did not mess up the phase or tone, but the in-line filter was less than fully transparent. I later upgraded to the battery biased Vandersteen crossovers, and the transparency was restored. The Vandy 2Wq is specifically desigend not to introduce phase issues with the main speakers.

bewoods1962:  Interesting observations.  I haven't listened to my rig without the 2Wqs since, well, since I changed speakers in 2009.  I don't notice the smearing you refer to with the M5-HP crossovers, but my system is not super-resolving.  I am curious:  What is your signal chain like, and what are your main speakers?  TIA.
