Hhh, trust me, this shiz is structural - I can see it from both sides of the wall in my case. I guess it was not the only force at that place - the house is settling still, so these were some kind of breaking points anyways, but yeah, that helped!
The cracks were not there before the TH was installed.
The house was built in 2005. We moved into it in 2009. The TH was built in 2012.
The 1st pic is the master bedroom doorway that is right above the 2nd pic mancave.
This is the 2nd pic's mancave corner.
The stairs lead to the master bedroom.

i can not recall who uploaded this pic, it is on the FT30 thread
i guess just one FT30 angled to the corner will make triple noise of what i have now
but
see this guy!
4 FT30's !!!
firing to the dance floor
he put a chair so we can see the size of the monsters LOL !

4 18SW115-4 's on my bucket LIST
the LABsub vs the FT30
who wins ?

why does 60-120hz in a high order qw hurt so much?? It’s not a ’good’ sound
The natural high sensitivity + somewhat higher directivity can make it feel like +6 - +10 dB conpared to normal ported design. That would hurt from any enclosure. These buggers really play a lot.
60-120 Hz boosted never really sounds good. Especially if the response above that is highly erratic. I built new kick bins several years ago, upgrading the old design to allow easy vertical stacking and smooth out the response while I was at it. They sound similar band passed 80-300 Hz. But the new smoother design is almost listenable run full range. The old design was horrible unfiltered. Hurt to listen to it, even at 50 mW. Either in a group of four could knock you on your ***, even with no subwoofer.
only linear response sounds good. the variation of what you hear must happen in the music.
and there is psychoacoustic
if you want music to sound loud then a cut off below 60hz can help giving this impression of loudness.
indeed you can turn the speakers much louder if you omit everything below 50hz

I think there is more to it. The chest biting output might not be only about peak around 60Hz, but of course, it often is.
i often wondered if the impact and (unique?) punch of the -roar- or -paraflex- designs wasnt partially the very pronounced 'peak' at 2x (roar) or 3x (paraflex) the fundamental, but also the motorforce and delivery of sound through the long skinny air column instead of a big chamber and small port?
would a very large helmholtz type resonator bandpassbox have the same 'impact/punch'?
is there something to be said for placing the driver at the very high pressure end of a long qw resonator by comparison maybe

Indeed! I 'chased' this down to 14 Hz Fb before I was satisfied, but in retrospect it was apparently due to my ~ lifelong exposure to steam locomotives and some of Georgia's granite/marble church's low B pipe organs.
This is the room
15' ceiling
47' wide
55' depth
The yammies in the back are 12' from each other and 5' from the floor
The woofers (I'm not calling them subs ..as they are 50hz boxes 🤣) are to the left corner in the back
Yeah there is a door lol , it is what it is 😸
The boxes are 2' from the corner
Do I need to put them closer?
They are not touching the wall as you can see
In the below pic
And a mat...yes, otherwise they walk away!!

already good. put them as close as possible to the corner.
measuring lowest frequency and adding a cut off below resonance and the sounds gets more clean and can be played louder

If I put the cabs one in top of the other ,they can be really close , maybe half feet close.
Does that help or stay side to side.
My HP is at 50Hz
I will align before Saturday
Hope that helps.
What you mean a cut below resonance ?
