Hi Guys, So i am not an expert with the set up of REW or sure if I calibrated my RS SPL meter correctly, or anything else for that matter in my Quad Stacked PB x000's set up.

I am using a Mac book laptop running 10.5.8 OSX with a Behringer UCA202 external sound card with the RS Analog SPL meter.

I have four SVS PB series subs placed in the corners which are slightly angled to the center of the room with
the PB 1000's Stacked on top of the PB 2000's.

As seen here in this Picture.



So I did a sweep from 5hz to 120hz , I put the RS SPL meter/Mic at about head level in my LP
with an extended tripod holding it about ear level where I would be seated.
I first level matched the subs with my PRE amp set to 0, and set the sub gain close to 75 db.
I found I had to set the PB 2000 much higher to get to the same db level. But I have theory on this I need to check.
The PB 1000's are "higher" up in the play back location, that is on top of the PB 2000. From the graphs you can
see how I think it might be a better location for subs but I need to take a sweep with them on the floor and not raised.

I will post the left side subs first then the right side subs and then the dual 1000's followed by the dual 2000's
on finishing up with an over lay of each set of dual subs over the graph of all subs.

I Think a better placement would elevate some of the dips, but I do have a SVS EQ I have not installed yet.
That will be fun with this set up!!!

And Quad Subs with the duals over layer.
