room setup suggesion needed

@m-db  well they are bit undersized according to QSF calculation how ever they are the biggest I was willing to deal with, still 157lb is not a Mickey Mouse 

Honestly system sounds really good, but better is enemy of good so is there anything I can do better or is there anything that I’m doing wrong ?

- Unless i missed it, i don’t see any indication of a subwoofer. So, that’s a couple of octaves of music (that the artist intended!) that you never heard yet.

- This is the kind of lumpalicious your room would look like (height assumed since you don’t mention it)...Depending on where you sat, depending on where your speakers sat, sbir, etc, there could be some lousy things happening to the sound (that the ears may have just gotten "used" to). There are threads here with material that covers what you could do, if such lousy things are going on. For example, the subwoofer, if implemented correctly is also a crucial "room treatment" device (it can fix things that conventional treatments can’t fix or the quantity becomes impractical, etc.) Have you ever measured your room? On a positive note, the fact that you have a big room is a good thing...lot of problems become easier to fix (big room guys = smaller problems, small room guys = bigger problems).

Ok let's clarify some things first, as far as I see you speak numbers and diagrams language so it will be easy for both of us.

You are one of us who use subwoofers, so let's do some logical calculations and see if it makes sense.

1. human can hear from 20Hz to 20KHz but in reality adult person will loose some of the top hearing so maybe 15-17KHz tops.

2. Best subwoofers operating  from 30 Hz to 50Hz, anything less like 25Hz and below will not be sound it will be more like pulse.

3. JBL 4367 speakers  delivering sound from 30Hz to 40KHz

So now, how is your theory of missing subwoofer works exactly when my speakers match frequency of the best woofers out there?

The idea of HIFI stereo was to replicate sound recorded or performed as true as possible and as realistic as the sound itself, so by definition adding components to the system that emitting sounds below hearing range, just to create boom effect makes no sense in my book. When you go to cameral quartet concert there is no amplifiers or speakers you sit and you listen people playing instruments, now those instruments recorded you replicating home on your HIFI it should sound exactly the same, there is no jackhammers under concert floor to create vibrations they do not exist just for the thrill of the spectators.

Now coming to the sound wave shown on your diagram, can you drop the ceiling another foot down to 8' I would love to see what will happen with the bounce of sound after the ceiling was adjusted.

What will happen with 38Hz point, if it will bounce  before 7.25 mark or after.

@ditusa ok I get the concept but execution could be tricky since they weight 157 lb each,

Ok.

The JBL 4367's are great speakers! See my system page, left speaker, I raised 9'' off the floor (the speakers weight 275 lbs each and are 36'' tall, 39'' wide, 20'' deep). I also decoupled the speakers, from the floor with concrete and lead It took two people to put the speaker on the blocks. Raising and decoupling the speakers from the floor improved the sound quality in my system and the cost was low. For more details see here. JBL speaker stands see here.😎

@ditusa  so what does rising speakers off the ground, and if I bolt the frame to the wall would it do the same effect ?
