Hey all,
I've had my four PSA XS15s for quite awhile now and have tried many, many different placement options...but I'm at my wits end trying to make sense of these graphs. With all 4 subs up front (in 2 stacks of 2) I get great output, sounds great, but my seat-to-seat variance suffers a bit....and my graphs look horrible! I only have to bump the trim +2db in this configuration.
With 2 up front and 2 in back, I get great looking graphs but the bass is thin and weak. I have to bump up the trim at least 6db to get it even close to sounding good. You will notice that I don't get much response below 30hz in this config.
What on earth am I doing wrong? I don't understand why the better looking graphs don't actually sound better....?
All 4 subs up front, Aud off blue, Aud on green:
