@Nwickliff You have a really nice looking space. I suspect
@Bliman is correct about the right front speaker, but also that the fix won't be hard or require much from you: adjusting your EQ, per channel, and making sure the front speakers are toed in and their tweeters fire at the height of your ears (they don't have to fire directly at your head, just at the general height of your ears). Your speakers have pretty narrow vertical directivity, which will persist despite the crossover fix, assuming it was done to correct the broad 2kHz defect. That said I still see the dip show up in your measurement #9. This is probably related to your measurement position, which was above or below the acoustic center of your speakers.
The 60Hz and 120Hz tails are related to some kind of mains hum (ventilation, fridge, something like that). Note that they are nearly constant, low amplitude, so not a problem. The 2.7kHz tail is probably some kind of electrical leakage from the UMIK microphone (see for example the leakage of 1kHz and harmonics in
this measurement) or your computer. It probably has no acoustic source, or you'd hear it.
The main audible problem you mentioned was vocal bloom, especially for males. I'm not exactly sure what bloom means but it seems to be another way of saying that the dialogue is unintelligible.
Some questions (I think you may have answered some of these in your videos but it's easier to have it all on paper):
- Are you doing MMM with all channels (fronts, rears, subs) going at once?
- Are you covering the entire listening area and more? (At least a foot in every direction, 360 degrees, with the center being your head at the listening position.)
- Are you moving your arm in slow circles or sweeping it from side to side? (Should be the former.)
- Are you facing the microphone at your speakers or pointing it vertically? (Should be the former.)
- Are you applying EQ to all channels at once or individually? (Should be the latter.)
- Are you applying EQ to the whole frequency range? (See below.)
- Does the position of the speakers in your video represent that final single point measurement (#9 in the mdat), or did you toe them in further? Did you ensure the microphone was at tweeter level?
- When listening, is your head at the height of the tweeter or above it? Does your "critical listening" position (when running back and forth, measuring, testing tracks, trying EQ tweaks) represent your actual position when relaxed, or do you tend to slouch or lean to the side or forward?
- Do your speakers sound good with your face right in them?
Whatever you're doing in the region below 100Hz looks right. The 70Hz dip is really small and can be ignored. Above that from 100Hz up to around 1kHz the response is mostly related to the speaker interaction with the room, aka SBIR. This is the problem region and won't respond too well to EQ. If you have to make corrections, make them broad Q: I suggest trying filters at 100Hz-200Hz, 400-500Hz and 600Hz based on measurement #9. Try to make multiple single point measurements around your listening position within, say a foot's distance, and compare their trend to an MM sweep to make sure the filters are in the right range. Anything above 1kHz is related to listening/measurement position and speaker response. Don't try to correct anything there other than dialing in a tilt.
The transition from bass to midrange is important for clarity and overall tone. Controlling the tilt there is pretty hard using manual EQ and requires a lot of trial and error, but can be done.
