oh...y’all talking about room mode peak.

agree can be very jia lat.

mine @ 45Hz cannot fix with bass trap, need to EQ it out; otherwise can trigger headache (for me)

Which means this compressive feeling will
happen some thing like "hit and run" at one
particular freq (in your case at 45hz)..?

Do you think it is nice to have all these
Such as sofa vibrate, win, rumble and
Deep thumb in your chest plus compressive feeling?

No, it's a physical pressure pressing on the ear, actually causing discomfort if you listen for prolonged duration.
And it's not because it's loud cos bros who come over will attest to how soft it is...
I may have three subs, but that's to even out the bass rather than for SPL. Same issue if I had one sub too...

Have you been to the doctors? Do check up, it seems quite abnormal. These pressure build up, normally happens with intense SPLs down lower freq, we are talking about freq <20hz type @120-140db or subsonic to cause the pressing on the ears. it stays on until u yawn or drink water, or press your nose and breathe out etc, that will release the pressure

In a smaller room, its easier to hit these numbers with room gain + if you have a resonant freq down low freq, that explains. So if other members who demoed and found a similar experience, then you can conclude its the room and subs. You then need to lower the levels on the sub until you are comfortable. If only you are experiencing this, then you probably need to visit the ear specialist. to see if there is any blockage etc

I suspect is the upper region frequencies (around 80hz - 110hz) that causes this .

1) Try move your seat front or back to see if the pressure reduce or gone or go to one side of ear . You can also  sit to the left/right sofa to check. Likely shift to one ear, I guess.

2) Turn off those subs that is/are doing upper frequencies region to confrim.

3) Try crossover your freq at lower freq like <50hz and check.

4) Try change the phase on the subs and check.

Thanks bros
I’ll try and move about
My room is almost a square so I wonder if that’s the issue too
4.02m wide
3.92m long
3.12m high
Subs on either side of my console - see my signature
Near but not exactly at the corners

Does the problem occur if you are in the room for the same duration but without anything playing (i.e. quiet)? Maybe it is the sealed room that created the issue?

No... it occurs when the subs come on..
If I play a tune which has no bass for example or an older movie with little bass, there's no issue..

Yah, go try out first and see if that is the issue. Usually a perfect null on listening position for about 70hz to 110hz can cause this issue on both ears . Other frequencies can too but not that obvious only and sometimes it feel good unlike the upper region which is irritating .

I had experience frequency from around 60 to 80hz from one of my sub... so I adjust that sub cross from 80hz to 60hz. The problem disappear.
As what Jason advise need to find which sub that give you problem.

Your problem is 99.9% of mine!!
I have the worst room dimensions - 4m x 4m x 3m.
My 45Hz room mode was so so very terrible...see the 20dB peak (blue line) around 45Hz.
When the SUB/L/R triggers it too often, I get headache..
Only solution is to EQ it away. Very difficult to fix using bass traps.




After I moved in, and with many many months of experimenting, I settled on the following PEQ to "tame" the room mode. It's a very deep cut of -4.5dB with very high Q (narrow band). I had to do two side-by-side coz my Yammy cannot target the problem frequency. Hopefully the setting helps (it's for Yamaha AVR). You may need someone to translate to your AVR Audessey setting. Try it...



If you're also experiencing a bit of honkiness in the male vocals:- centered around 450-550Hz, knock back slightly, wide Q (say 0.5). Trial and error until you're happy. I think the 4m x 4m room causes some of this honkiness.

 :)

If music double-bass note keep hitting (repeating rhythm) the mode frequency, very very jia lat.
If HT a lot of bass keep trigger the mode frequency, also very very jia lat (eg. 13hrs Benghazi, shooting and bombing)
After EQ, music & HT so much more enjoyable. It can still trigger every now and then but the amount of boost is far lower therefore decays quick enough.

Hey Pete, load up REW and play around with "Room Sim". Below is the simulation of your room dimensions, look pretty much like the same problem as mine (coz of the almost identical dimensions). You can shift around the speaker locations, MLP position to match your room and see the simulation results. You might be able to find a better MLP (assuming you can shift your seat slightly away from the back wall).

Pete, you got me curious what wrong with your setup...As such I'll pay u a visit on either 27 or 28 Sep 19. Let me know.

Thanks for the offer bro..
I'll love to have you over for a review and just to tap your brains and listen to your ideas on HT.
And thank you everyone for chipping in, I'm waiting for a bro here to reply and confirm, that he is coming over to help do some measurement the last Sunday (if that happens, I'm happy to invite others over so they can perhaps learn form my mistakes on how to prevent this)


Bro Boxer - I've actually done the room sims with REW, and with Jason Yeo's instructions, I've moved my MLP and done some tweaks to the settings and am running Audyssey again right now.


I'm very happy with the surround experience I'm having, but bass continues to be such a weight on my shoulders I'm almost going to give up. I've told many bros that my skills suck at this (look at all my threads over the years) and I'm still a baby here.. learn from my mistakes on what not to do man...


Will report back and hope the bro is able to come ...

A little update:
Moved my seat - according to the REW sim, now sitting nearer the screen, and slightly more central.
Crossover for fronts and centre at 40Hz, sides and backs at 80Hz, Atmos at 120Hz
Running as small
LFE crossover at 80Hz
The response curve from the Audyssey app is more flat - didn't try to boost the lower response
Using Dyn EQ
Less compression but much of the mid bass seems lessened.. I'll see if it sounds ok.

One positive effect is the the surround envelop from this calibration is even more immersive than before. I might stick with this for a while whilst I await some help.. I will trade bass so I don't get the discomfort in my ear... (it occurs even at lower volumes and I don't really want to bust my ears)

is your new seating position 1m from back wall? if it is, then it is similar to my MLP. i found this position through a lot of trial & error. most balanced for me.

also, if there is a chance to shift LR speakers, try to place them about 1m (just under 1m) from side wall. i also found this final position through a lot of experimentation.

sharing my positioning since our room dimensions are almost identical.


hope this helps...
