Re: REW Noob

So I guess the two filters would be a good place to start. I guess the two dips it shows really will not be the true response once they are applied. I have been watching for a used 1124P. They seem to be a pretty hot item. They go very quickly.

I demoed War of the Worlds and there is just a tremendous amount of more bass now. I know I will not be needing any buttkickers any time soon.

I am still trying to wrap my head around the whole house curve idea. How do you go about seeing if you need one? Do you have REW play a 100Hz sine wave and then a 30Hz and see what volume difference you hear?

I have read the link you posted a couple of times. I like what he says about changing the vertical limits. My graph looks a lot more subtle that way.

Re: REW Noob

I use the Hard Knee HC for movies only and switch back to a standard curve for music titles. I just like the way it sounds and feels for movies. I am going to change the gain on the filters to reflect the new vertical limits and see what it sounds like.

It created a filter at 49.1 Hz with a -14 gain and one at 71Hz with -9 gain.
Did you use Optimize PK Gain & Q?

Re: REW Noob

I just did...

1. Find peaks between 20-80Hz.
2. Assign Filters.
3. Optimize PK Gain & Q

And....

Re: REW Noob

Increase the cutoff frequency for the subwoofer target so that it matches the cutoff of the MBM then redo the optimise for the filters, at the moment the target is not correct for the system.

Re: REW Noob

weverb, you are one BFD away from hearing the dotted line in your room.

Do you have a Birthday coming up?

Sorry John, I am still very new to this and really appreciate you commenting on my situation. Is this better?

Simply set the cutoff in REW to the cutoff of the MBM module, so you can include the peaks that it is responsible for...

Gotcha. That's is what I did. My MBM is xo at 80Hz. I did a search for peaks between 20 - 80Hz.

Although looking at my graphs, I have been debating about playing with the xo point. that transition between the MBM (80Hz) to the highs does not look smooth. Just a reminder, the last few graphs have all been with the mains on.
