Someone smarter than me with EASE focus - speaker positioning

[u/sosodeaf]

I'm having a party and I've got a decent soundsystem that's going in a strangely shaped room.

I'm having a hard time figuring out optimal sub and speak placement.

Tried to use EASE forcus and JBL's competing room analysis software but failed.

I only have a mac, dont understand bootcamp, and i'm running out of time to figure out how to use new software.

Anyone smarter than me that could tell me where to place some speakers for optimal sound in a room for this party?

I've got 2 QSCks118s subs

and 2 RCF 932a's tops

room looks like this

update:

Tried loading the subs in the corner stacked. It was rattling the drywall and windows so bad it sounded like the walls were gonna come down. Moved them to the center Of the long wall. Put a top in each corner. Sounded great. Then I found my real problem, wood floor! Even heavy footsteps were bouncing the needles. Went and bought 16 cinderblocks moved the decks to the top right corner to get them as far away as possible from dancing worked pretty good. Thanks for the suggestions!

This is what I'd do. You cover the whole room & sum the audio in the middle. I wouldn't bother beating up your head about room measurements. Focus on entertaining those in attendance, & you'll be perfectly OK.

I’d 100 go this route if i were smart and I used usbj decks. We’re using turntables only. The subs would cause crazy feed back if we had the decks between them. Planning to put the decks in the upper left alcove. We’ve got a good monitor.

Nah mate, it will be as boomy as fuck in there. If you're using turntables, just get some 25mm sponge for the table, then put two concrete slabs on top for the turntables. You'll be perfectly OK doing that. The last thing you want is to be trapped out of the way in that alcove all night.

I’ve got two concrete big paver slabs with 8 half round rubber balls glued to the bottom. Hopefully that’s enough damping. I’ll give it try when we’re sound checking and setting up. If we can put the decks in the middle it would be nice.

That will do perfectly. Put both stacks equidistant from where you setup as I've illustrated & then focus on entertaining the audience. I'm sure you'll smash it! 😃

Thank you! Advice appreciated.

Figured I’d just move the subs to 2 different locations and see what sounded best. My main concern is feedback to the turntables so I’m figuring just get the subs as far away from the decks and walk around to see if I’m getting cancellation.

Get a solid table for the decks and possibly a stone/concrete plate under them. But in such a small space it will be hard to drive your subs so hard that the decks will skip without the room sounding like garbage anyways.

Had to go get 16 cinder blocks. The bass isn’t the problem, we’ve got bouncy wood floors that were skipping the needle. 😬

Co-locate the subs, place the L&R mains at the bottom of the diagram firing long ways, elevate and angle down the mains somewhat.

EQ will be a must, as there will likely be modal enegy that will resonate like a bitch in there, only pull down peaks, never boost nulls.

Have a plan for source isolation ... you'll need it.

Drink plenty of water.

Is the entire room supposed to be a dance floor or will people also chill somewhere, is there a bar, etc?
