Am I crazy for abandoning Room EQ?

Moving the speakers to delay the early reflections, and minimise their amplitude usually helps.
I am somewhat intrigued by Lyngdorf's approach of placing the woofers at the corners and using high crossovers.

But “essential” is clearly a subjective call.
Depending on the room, it is more essential in some cases than others. If the speakers are to be placed in the living room, it is very difficult to have anything close to good acoustics. If your sofa is against the back wall, all is lost without at least some EQ.

So, in the last three years I have went from a simple Yamaha AVR using YAPPO for simple distance and level adjustment to a Monoprice HTP-1 using Dirac and really diving into making my own house curve that didn't change the FR of the speakers too much past 500Hz (used the Harman house curve basically with more bass added) to a Trinnov Altitude and using a similar house curve to now an Anthem AVM90 and only using ARC EQ up to 500Hz.

Through them all, I still never felt like my Funk sub was being EQ'ed properly as there was a lot of oomph missing that I knew the sub could produce (being a 21", 2.4kw beast).

Recently I got around to using the Funk subs built-in DSP software and making my own PEQ adjustments to get a flat response: before, there was a +12dB peak between 30-45Hz and a -8dB null between 65-85Hz. The large difference between the two would always have any of the Room EQ software "neutering" the sub and favoring a baseline EQ target that used the peak instead of cutting the peak to get closer to the dip.

What I found doing my own PEQ is I can safely cut the peak and bring up the null for a somewhat flat (+/-4dB) response curve from 15Hz to 100Hz. And using reference level testing material, the sub handles it (no limiting, no distortion, etc).

By and large, the sub/bass sounds the best it ever has in my room with just using PEQ on the sub and letting the speakers play unaltered (no Room EQ). It also helps I have Revel Be speakers for the LCR and a decently treated room, so the natural sound above 200-300Hz is perfect to my ears in my room.

With all that said: am I crazy for completely abandoning Room EQ and letting my speakers play as they are in the room with just simple PEQ adjustment to the sub?
I am even contemplating selling the AVM90 to pocket the funds and just get a simple (but well reviewed) pre-pro or AVR at this point.

Again, crazy?
Room corrections from listening position only works below about 250-300 Hz, no matter what the companies say. So no, youre not crazy at all.
To make this even more logical, - most of the ”roomcorrection” programes in AVR:s are badly executed, gives badly advices during measurements and sound bad. They are often salespoints and a piece of crap.

Much better results can be had by doing the loudspeaker setup in the room where they sound the best without any roomcorrection, and then do as you did - make the corrections where the fundamental roomresonances are, at the bass frequencies only. Sometimes the best roomcorrection results is done only below 80 Hz , correcting only the rooms fundamental resonances. ( the sound bouncing wall to opposite wall, and floor to roof.)

If you live in a rectangular room, you can measure the distances between walls and get the exact frequencies were troubles are.

As some people already have mentioned - the prefered Harman curve in the bass is very real = + 4 dB shelving from 100 Hz and below gives better sound results. But with that said - thrust your ears. If it sounds bad but measures good then something is very wrong.

Edit : many automatic room correction programes uses high Q corrections ( more than 7 ) in the bass register. Those sound often really bad . Try to go in manually If it can be done, and change any Q = more than 7 to values below 7.
’ie only use peq with Q lower than 7 .
The corrections made below 250-300 Hz often only need half of the measured value to sound good.
