Room Acoustics With Vaulted Ceiling

Will the vaulted ceiling go L to R (with the system) with the high point in the middle or will it go front to back with the high point in the middle of the longer length? I’ll assume the latter.  If so, you will want absorption on that angle that will send reflections back down right to the back/top of your head.
Also with that width, you may want to try diffusion rather than absorption at first and/or second reflection on side walls. 
Off topic, dodgealum, do you have the VTSP-360 yet? But maybe we could PM to chat about it... 

Thanks, @jriggy Not the best at describing these things but the high point is at the middle of the longer dimension with the peak roughly directly above my listening position. Happy to PM about the 360.

I'm in the corner so that my two-story tall vaulted ceilings are higher on one side (~23') of the system than the other (~13') and this forces me to use balance control to even out the imaging. Just something to keep in mind as you do setup. Hopefully not a problem if you're symmetrical.

And while I do believe the room helps with imaging due to the elimination of many traditional reflection points, I have many bass modes that cause very troublesome drop outs across the space (open to the rest of the house on both the first and second stories).

I hesitate to mention it given @erik_squires unprovoked attack, but the only solution I could find is a distributed bass array and even setting that up in conjunction with my full range speakers has been a substantial challenge. REW (free) and a calibrated usb mic (~$120) have been very useful for understanding and addressing these issues.

@erik_squires Please refrain from your efforts to turn every thread on this site negative.

Lots of good advice here from others, hope the new room is a great improvement. Good luck!

That sounds whiny and terribly sensitive. I thought we were supposed to toughen up and take it??

I made a 1 sentence quip, which is actually very funny, if you had seen the history of Miller following me along from thread to thread and answering all things audio with the swarm, and you think it's brilliant to quote tag me in a paragraph, fueling the fire. Maybe quote tagging me that way won’t take this thread anywhere you want it to go? You would not be the first person to derail a thread by putting all their energy into that idea.

Alternatively, you should have just let it go, and the thread would have proceeded along on it’s original intent.


Best,
Erik

Hopefully commentators will continue to help educate the original poster and those who face similar issues in the future.  Plenty of good education in here. Sorry for distracting.
