How much does reducing reverb/decay matter at low-frequencies? From my understanding of the below paper, it’s hard to identify differences in decay times/reverb at low frequencies (100Hz and lower). Research paper suggests long decay times (well over 1 second) can’t be distinguished from shorter times at low frequencies. If that’s the case, what’s the use of using thick (very thick) bass traps to reduce low-freq decay?

Also,

Can changing the subwoofer location help with decay times/reverb for the desktop setup?

Does using dual subs help with low-end decay times?
