gig at wide room

[BoostFab]

edit:
Is this an optimum speaker placement for a wide venue?

Four: OT12: Two fire toward the front of stage; and two angles out to the long ends.
Two: Titan-48: Load at the back wall.

What do you think, any suggestions? Thanks.

I think you mean wide room, and yes, that's the way to do it. You'd probably get the best results with the OTops stacked, the lower cabs aimed outward, the upper cabs inward. That would shoot much of the HF content above the audience in the center of the room closer to the cabs.

Thanks!
yes wide room, it will stacked; it's kinda of hard to illustrate that in the diagram above.

Depends on your goals.

If you can get the T48 under the stage...V-plated into the wall that is the best place for them. Otherwise, off to one side of the stage is good. I specifically built T39S to fit under stages just like this.

I would move the OT stacks toward the long wall on the top of the diagram. That additional standoff distance will allow for better integration with the subs, will limit the zone of death in front of the speakers on the dance floor, and will take advantage of the wider dispersion of a melded array (if any).

If you want even coverage of the whole room, divide the long wall into 5 pieces, and have an OT at 20% 40% 60% and 80% across the front of the room.

If you want to focus the sound on the dance floor, then a stack with the lower pair crossing about the middle of the floor. Aim the upper pair out for the dinner hour. If possible, rotate the upper pair to be inline with the lower pair for the dance part of the evening.

PS: Out of curiosity, what's the venue? I have been in most of the large ballrooms around DFW over the years.

thank you for your suggestions

Depends on your goals.

the goal is for best sound coverage of the entire reception area. The long throw of the OT12 takes care of that

this option is not possible, the stage is about 1.5ft tall prebuilt, no access to the underneath.

the fucus is coverage of the entire area, during the reception, but also important to have good coverage on the dance floor when time for the guests to dance.

Question For you about the Sub placement on the back wall like that....How do you Time align the Sub to the front stacks? You have one front stack 4 times the distance away from the other, as they relate to the Sub. Do you just align the one stack and live with the phase cancellation around the crossover frequency with the far stack? That's something I've never understood about Corner Loading the Subs. It seems impossible to truly optimize, phase and time align at least one of your stacks.

It seems impossible to truly optimize, phase and time align at least one of your stacks.

It is, and except in extreme circumstances is doesn't matter all that much. You simply can't hear delays of even 20ms below 100Hz. Your ears are too close together.
