The term "suck out" is a bit of a myth. There is no way to subtract from the sound that is coming out of the speakers. Generally speaking the "room" causes nulls, peaks with decay (reverb) so treating the room brings you closer to what is actually coming out of the speakers. Now with that said the human ear may prefer some of a room sound, which is why we try to treat a room that does not take away ALL room "sound". The trick though is to do it in a way that does it correctly across the spectrum.
1)Absorb as much of the low end so the bass is smooth/punchy.
2)Semi absorb mids for the same reason.
3)Upper frequencies absorption, but retain as much of it (later reflections) to give a "sense" of the room without it being the main focus. This is where we can start to use diffusion to help delay/change the upper reflections arriving at your ears.
Now to get to your room, you really cannot over absorb "bass" (suck out) so sure adding to every corner will only tighten up the low end. Basically letting you hear what is coming out of the speakers without decay with nulls/peaks. With that said though the soffit is a full range bass trap, so it will also absorb the mids and upper frequencies which you may or may not want. In a case like yours I would custom build them with our limiters in them so it will reflect upper energy back into the room. FYI this is a big reason we introduced our Alpha and Impression products.

Are you suggesting Alpha 6as for the first reflection point?
I have some extra low end bass signal I need to deal with
I replaced some Real Trap corner bass mondos (
Curiously via REW tests I found a 1ft 4" digi wave impression series bass absorber/defractor does the same amount of dampening using the back side facing the corner for absorption. My speaker manufacturer uses this technique in major audio show hotel rooms.
I have 2" rectangular 2ft Braid for first reflection
2 2" rectangular 2ft braids in back side wall areas
I am considering 4 range limited soffits for the front corners
anything on the back wall?
should I reconsider my 1st reflection points?
thanks

I used to have my system on the long wall
it sounded incredible
great tonality, dynamics, imaging
just corner traps, art panels
the 27ft width made side wall reflections a mute point
2 record cabinets were at those points
