Sub settings are the same. Our room is surely very difficult to tame Big and open. Basically no wall on one side that's open to the kitchen area. Half the ceiling is 9' and the other 25' tall.
Should I twist some knobs on the subs to try and get them to match? I'll move some furniture around next time and see if I can tame 350Hz. None of the acoustic panels were in place. I have three and there 2x3'x2" thick.
It sounds good though and am somewhat surprised moving the speakers a bit flattened the high end. Speakers are 6' from the front wall 8' apart.
Ok, that makes sense. I bet the reading for the speaker near the open wall/kitchen area is the one with less bass since there are less reflections. I wouldn't change any knobs then. If the amps are the same then we're just seeing room stuff and I would leave it alone because it is summing well.
It's good to sit where the tweeters are directed straight at you. If you look at the horizontal off-axis frequency responses on most speakers you will start to see them change at some point. Then, if you sit in a spot where you get hit by both of them off-axis you have more problems. Additionally, if the speakers are hitting you at slightly different distances then certain frequencies will be out of phase with each other (which is what we saw on an earlier graph). If you want to experiment. Move your mic around in the room (up, down, left or right). Then measure in those places and you will see the problems I'm describing. You can also hear it. Walk around the room while music is playing. Where is the bass louder? When do you lose the shimmer on the cymbals? When does the kick drum punch more? You hear the phase as you move. It sounds like a phaser or flanger guitar effects pedal on everything. This is unavoidable, but fun to observe.
As for the 350Hz problem. I'm guessing that this is actually a floor reflection given that the waveform for that frequency is a little bit over 3' long and your speakers are 6' from any wall. I'm guessing that the mid range drivers are around 3' from the floor. Some good rugs under the speakers and/or in the distance between them and you or behind them on the floor might really help. Even knocking it down a few db would change it. Otherwise, don't sweat it if you like how everything sounds. All rooms have problems. There are other options like adding some DSP to fix that spot or even integrating a passive circuit into the speakers to reduce it.
