tomorrow i'm loaning a sub from my local hifi store. this will be the first sub to grace my system, and as i'll only have it overnight i'm trying to anticipate integration problems in advance.
i have a 2 channel system with denon 2200 universal as source. the player does have bass management for 2-channel which i'll use, setting my dynaudio 52's to 'small' at 80hz.
unfortunately though,it doesnt have speaker/sub time delays in 2-chanel mode. the sub, a dynaudio 250, has phase at 0 and 180 only(not 90)
while i know that i should run a frequency sweep at the crossover frequency and choose the phase setting that maximises volume, this only tells me which setting puts the sub most in phase, doesnt it?
is there any way, through physical placement distances, or any other way, that i can know the sub is exactly in-phase with the speakers? i'm guessing if the sub is at the same distance from me as the speakers then all will we in phase. but minimising nodes, maximising bass, as well as the wife, might require placement somewhere else.
if, say, the sub is twice the distance from me as the speakers, will in be in phase agian?(but of a different cycle?); or if i put the sub at 50% past the speakers and inverted the phase 180 might this do the same?
any other ways to optimise phase? can the subs filtes slow down and delay its signal thereby effecting phase.
and if anyone has any suggestions where to place sub so as to minimise axial nodes, i'd be most gratefull. i'm thinking near the front wall(not corner) as i read somewhere it might be a good idea to put the sub somewhere between the speakers. but if i put it behind the speakers near the front wall, at say 2/5ths along the front wall, that puts the sub at twice the distance from me as my speakers which are 6' out into the room. this is why i'm worrying about phase abnormalities.
sorry, long post. thanks for any input anyone.
