if you pull the peak down around 45hz a little, it may not 'boom' quite as much.


the 25hz peak is probably fine. a little extra fun for movies.


its not that bad of a response.

Listen. It's All Good.

also, if possible, experiment with some placements/rotations etc. aiming it about a half a foot from the wall may eliminate some of those cancellations. it is tough to make a suggestion without knowing the room...

A couple of questions:

Have you read and followed AustinGerry's 109 page guide? If not, it's a must.

Is that a single measurement or an average response? I'd take a measurement a foot in each direction around where you plan to sit and then hit the all spl graph button, then hit the average button in that window and eq that average measurement.

Why aren't the hz under 25 registering? When I see other rew charts it seems that the dbs for hz start under 20.

Not sure it's a sticky anywhere.

Once done with that, if you have multiple subs or want to best integrate your mains with your subs read up on mgt90's thread/guide here:

Just for giggles, switch your phase 180 degrees, and take another sweep.

I'd also like to run sweeps at a higher db, but the mic clips at 85+/-. How can I raise the mic threshold and run sweeps around 95db. Maybe this will give me a better idea of the lower hz (under 25)?
