I must apologize for not being specific in my question. the two main
speakers are full range, five drivers floorstanders, rated to 22hz.
the rel stadium III subwoofer is connected with the typical neutrik
cable. in paralel (high level?), the crossover setting is 22hz, which
is what bugs me... the reason I have the sub is to complement only
the last octave of the sound spectrum.
I still get this strange mid bass suckuout problem in one of the two
speakers whenever the sub is activated and dependently from the phase
setting, 0 or 180, the L or R speakers will be affected.
the mains are in phase with each other. I checked the connections
several times.
unfortunately the system is located in an L shaped living room. one
speaker seats in the corner with the sub behind, and the other
speakeris in the open, meaning that it does not have a side wall and
associated reflections. just the wall behind.
I cannot move speakers around, they are heavy and the living room is
saturated with objects and furniture.
my question is: why the subwoofer appears to be in phase with one
speaker only -while the two mains are in phase with each other? Is
phase problrem directly proportional to the distance between sub and
speakres? I say that because one speaker is definitely closer to the
sub then the other.
however I could easily live with this "problem",
I would like to understand why that happens.
aside from positioning the equal distance from
your L/R front speakers, you might want to consider
running 2 subs; see:
