Cause of boomy voice?

[dweeeeb2]

When watching movies I’m finding voices to be boomy. Looking at these graphs is it that decay time above 70Hz causing it?
Any suggestions? Could I just EQ that range down to minimise the decay volume?

EDIT: Small odd shaped room very approx 4x5meters, reflective floor (main living and traffic room - not many options to change)
Mains: Lintons Sub: Monolith 12” 500W, Marantz Model 30 Amp (200W(4ohm)), MiniDSP HTx using Dirac as DSP, source select and pre amp.
Graphs measured at MLP. High XO at this point, 20Hz<Sub < 170Hz, 150<Mains<15kHz

More details about what your setup is and the measurements are might be helpful....

Could you measure again with a longer time length (1M):

Cross correlate align the measurements, discard "bad looking" measurements if there's any (see IR plot) -- thereafter vector average and upload here.

…. and don’t use 1/3 smoothing but either Var or 1/24 so we can actually see what is going on in the lower frequencies.

Your waterfall seems to indicate a resonance at around 60Hz or so. But the FR doesn’t show it, probably due to the smoothing.

Likely there is a resonance around 100hz, which causes the issue with booOOoomy voices. Change the scale on the spectrogram from 1s to 100ms, and you will see it.

Thankyou guys will do in a couple of days, family back in the house
Must keep the peace

BTW, when testing the effect of EQ applied to the center channel, solo it or mute the rest of the other channels. Keeping bass management is fine as long as you turn it off for the other channels.

@Kvalsvoll is probably right about 100Hz. I am curious to see the mdat just for a closer look. I’m curious to compare my center measurement with others... At my couch center MLP there’s a significant upper bass to low-mid hump. It’s not boomy, but it makes voices sound louder and causes some slight excess in center channel localization. Because it’s caused by boundary reinforcement, the over-boosting effect is seating position dependent.
