Re: REW Noob

So brucek which do you think looks the best so far? I am thinking Graph #2 (MBM XO Out (0,180) Mains On) in the first group of 4 graphs. I am going to try to reposition the MBM to see if it effects the 80Hz dip.

Re: REW Noob

I'd say graph 1 looks the best.

It's a lot easier to do comparisons by using the REW Measured Tab..........

Re: REW Noob

Here is a new graph with rotating the MBM 90 degrees (port facing lp) and switching the phase to 0. Mains are on.

Re: REW Noob

Well, after more playing around. I switched...

1. Main sub to max extension
2. MBM is rotated 90 degrees w/port facing lp
3. Main sub phase is 0, and MBM 180
4. Turned up main sub from 4.5 to 5
5. Mains are on
6. Receiver pink noise leveled mains at 75dB and subs at 78.5dB

Re: REW Noob

Hey weverb,

For me, I would want more in that 20-30Hz region. I love movies and do very little music except for BR & HD-DVD concerts. I am trying to set up several presets on the BFD to compensate for concerts vs action movies.

Re: REW Noob

Hey Larry,

I was thinking of adjusting the target up to 78dB and then start looking at applying filters. I do not have a BFD at the moment, but was just playing like I had the ability. Below is a graph of what I was thinking of doing. I know I should not be using 12 filters, I am just playing right now. Let me know your thoughts. The other option I was thinking of trying today was adjusting the main sub up some to increase the 20-30Hz range. Anyone's opinion?

Re: REW Noob

Hey weverb,

I would try and lift the 20 - 30Hz region with placement and sub settings and not with an EQ boost. You had a graph before that looked really good in this region. I have also gone a bit over the top with the 12 filters and I am heeding the advice here to limit the amount of filters.
