Re: 1st day using REW


Ok, I ran it, and recalibrated with the mains running, I moved the speakers everywhere, but there is a nasty dip centered around 111hz, it MUST be the room, I will have to treat the room to get rid of it.
I adjusted the phase, and it WAS around 125deg, and it's sitting at about 45 now.

It's hard to judge exactly WHERE the XO is on the sub, because most pot's I've seen(and used) aren't linear- Audio pots are supposed to be better though... I tried what looks(on the dial) to be 100, 110,120, and full blown 160.

The farther I move the XO, the peaks(low end) get higher, and pinches the dip narrower- but to no avail........
I am trying to determine between 110 and 120, 110 has a couple SMALL dips below 80.5(target), 120 is high enough over, that I could EQ it DOWN flat.

I am attaching the jpegs for you guys to look over(TOP is 110hz,bottom is 120hz), any advice is appreciated, but I'm thinking the 120 and get rid of peaks, I'll have a bit more headroom for the smoothing... at least thats my theory!! LOL (plus the dip is narrower a bit, and doesn't extend down as far)...
It's obvious that the room needs work...

EDIT: if the horizontal scale should be set different, let me know I can extend the upper end instead.

Thanks Again,

Gary
