Room Bass manipulation...do I have a problem?

[Dguitarnut]

I have an 11x15 foot room 8.5 foot ceilings with sliding glass door on both skinny ends. I have my 2 speakers 8 foot apart with one on skinny wall and other on long wall....so the listener is actually facing the corner with his back 3 foot away or so from a long wall.
I like the overall sound I'm getting but on some material I'm no getting as good a bass I would like to. When I stand in the furthest corner the bass is fantastic if not a little overwhelming. I cannot move the chair there because of the doorway I would be blocking plus my view out the sliding doors would be obstructed.
So my question is what kind of treatment can I use to shift the bass to my sitting position? Will bass traps in the corner with the great bass just decrease that and perhaps further decrease the listening position bass? I do not want that.
Would diffusers in that corner work?
No room for subs.
Thanks
Larry

Larry - you can't shift the bass. You can diffuse and absorb bass, but you can't shift it. The first thing you need to do is find the best seating position in the room for BASS. Everything after that will follow. The best way is to play pink noise and move the microphone around monitoring the bass waves as you move the microphone around. You are trying to find the FLATTEST bass response in your room.

Can you give us an idea of your system?

If you put diffusers in the corner where the bass is strongest do you think it might reflect and increase the bass at the listening position?
My system consist of Pass Int-60, Harbeth Super LS5 PLUS and Yggi DAC streaming Tidal thru a MacBook Pro
My listening position is non negotiable (view of Sunshine Skyway bridge 7 floors up). Lol

You can certainly try it as it may level out the bass in your room, but chances are, it MAY effectively sound like you decreased the bass. What you may want to do is add a couple of REL subs.

Bart Andeer of Resolution Acoustics is located in Tampa. Tell him Mike from Suncoast Audio sent you. He's an excellent resource for room treatments, setup, etc.

+1.

If you can't rearrange the room, a subwoofer or two are your only solution.

I have tried a single sub and could not place it in a good enough place sonically or physically to sound to my liking.
The sound is really excellent to my ears except for maybe on some classical heavy rock it sounds better in the corner behind my chair.
I will call Bart up at resolution acoustics and see if he has my ideas. Thanks Mike and everyone for your input.

I'm sorry to say this, but you can't diffuse low end.... you can ceirtanly absorb it with aproppiate treatment ( not acoustic panels ) you need real technology like membrane absorption or helmholtz resonators, below 125 Hz the "acoustic panels" won't do anything.
Difussion works above 400 - 500 Hz.
Adding more bass wont help either!! so more subs are not the answer! first take care of the acoustics.

We fixed his bass issues. He now has Magico S3 mk2’s properly setup. No bass issues anymore!

Amazing ending to a tale of too little bass.
