Thank you, will give it a try. 

I should mention this room is very open with only 1 corner, no back wall until about 20 ft behind listening position. Other side wall is open for 5 ft at front, ceiling slopes on front wall from 9 ft to 20 ft.  I don't think most rooms would need 13db boost at 20hz

In my case, using 4 subs, two front and two back, how might this play out?

My only EQ has been done with my ears. My Yamaha CX-A5200 can do all the magic calibration stuff, but I just use my own ears.

 

Note the rear subs are about 4 feet higher than the front subs. So by default, the rear subs are raised, and at the ear level of front row center. But they are aimed at a 45 degree angle outboard, with the idea of reflecting the sound off of the side walls.

I bet you had some good guidance!

 

We have an elevator in our home, and this is what we always use when moving anything (RF-7 III's) that is heavy and/or bulky. No way would I attempt carrying large items up a stairs!

 

So my subs got elevated before they got elevated.

That is not a sub that is a very large midbass cabinet with not much output below 30Hz even eq'd and placed properly.  It will have midbass output 40 - 80Hz in spades though.

I see. Wrong. But I see.

Who the hell came up with that bonehead idea?🥵

I did something similar when I delivered my Tiger Wood Jubilees to a guy in Toronto. EXCEPT we had gravity working for us going down the stairs not up.

We do some crazy stuff,  but this one was pretty scary.

The other consideration is the floor surface. Is it tile, hard wood, concrete, or carpet? 

My theater seating is a series of 3 riser platforms. The rear most two subs are elevated as a result, being nearer the center rows ear level. The front subs are in corners, at floor level, but near ear level for those seated front row center.

 

 

beautiful cinema room ,  how many speakers are you running ,
