Freq Response for My SVS

[STRONGBADF1]

No i dont have a PEQ on the SVS PB12 +2. I called them when I got it and they said that the one that comes in black ash finish does not come with it. i have the EQ on the receiver set to auto. Crossover is turned off on the sub and X at 100Hz on the receiver Xover and phase is reversed. if you look pack at previous post you will see reverse had less of a dip.
I have mine in tuned to 25 Hz because large room 24x16 with vaulted ceilings and I believe 25Hz gives more output.

That makes sense.

How the FR look at 100htz?

I've found localization has more to do with placement than crossover In my experience. 100hz was less localize-able for me actually. It's a strange mystery, but rooms are weird things.

Rooms are weird things. In my family room if I put the sub in the right front corner I can localize the sub...left front I can't. (crossed @ 80)

I will post it as soon as i get around to measuring. Busy this morning taking care of the lawn, watching football today and watching over the little guy. I hopefully can get it done tonight.

try to solve the suckout by changing the phase

Yea, I did that. It was even worse before > 20dB @ 70Hz. My little room is problematic.

so was it better in reverse?

Behringer

based on my tests do you think i would benefit from Behringer destroyer 1124?

Yes, identical to yours.

It might be, but you should try playing with other variables like the position of the sub and the crossover before going to EQ. Most of what I see in your room is nulls, not peaks. Nulls are harder to treat with EQ, though most of yours are not that deep.

Xover

I tried the Xover at 100HZ and there were even greater dips.
Here are results of it crossed at 80 HZ reversed phase.
The question I have is that the crossover is set at 80 HZ, I thought at around a frequency of 80 and above the response would start to roll off but I see no evidence of this. I measured from 20 hz to 110 Hz. Does this FR look like there is no Xover enabled. I did this test with the Sub only and no mains.

Yup, the 80Hz crossover looks better.
