Re: Using REW Waterfall to calibrate sub instead of FR graph


Hey Guys,
Sorry for not replying sooner, been out of town the past 2 days.
My room is rougly 16x17.5x10. 2 of the walls meet the ceiling at 90 degree angles and the other 2 are vaulted into the ceiling. There's also a hallway off the front right corner of the room. Sub is an infinite baffle with 4 15" ascendant audio aresenal's mounted in the ceiling out in front of the screen a little bit.
Measurements were taken with a behringer ecm-8000 at the seating position (my seating position). I'm also using an SMS-1 to smooth the response. It was pretty good before but the SMS allowed me to get it even better. And I still have some tweaking to do.
I have 8 1" acoustic panels around the screen and 3 on one side wall. The other side wall has 3 windows which are covered with drapes. I also have 4 4" thick panels that I made (2'x4' with 6lb density fiberglass). One straddles the back corner and the other 3 are hung flat in other spots.
Here's a full range sweep of the sub and left front and some pics of the room.
