Actually I can't touch a drop of alcohol so i have to listen to Karaoke STONE SOBER!!!!!!!!:sqfrown:

I did one shot with a lady that was here at the studio to record a couple of weeks ago and damn near fell out from sugar shock!
 
I hear you. I just don't drink very often at all. Too many painful memories of family members.

When I do it's to celebrate something really big (upcoming Steelers SB victory???), and I pay for it.

Splayed "angled" away from each other. This does two things, it increases the coverage area and again reduces combing! How much "splay" depends on the projection of the horns! If these speakers had a very tight horn say 30 X 60 it might not be a problem with the inversion of the top cabinets if the bottoms were "tipped down" say another 15 or 20 degrees.

Actually an outward splay angle will increase comb filtering - by increasing the distance between the centers of the speaker elements. Splaying is another thing that has been known to be wrong for at least 25 years.

Vertical arraying of sources is preferred (i.e. line array). Turn the tops on their side and vertically stack them with the HF elements in a line, and the woofers in a line.

Alternatively, place the boxes at right angles so that the elements will crossfire. This will help to minimize the distance between the elements, and will reduce (but not eliminate) the comb filtering that will happen.

One other thing I don't like (and I may be wrong about it you just can't tell from the pic) is that it appears they are using chain for mounting their speakers! I like solid mounting systems when flying cabinets.

I prefer braided cable for any overhead applications myself. But, in this case, chain is acceptable. Given the size of the photo it is difficult to know for sure, but the rigging for the flown speakers appears to be reasonable.

Sorry but I guess you need to read a little more on the subject of comb filtering the overlap of the horns projection is a large part of the cause of comb filtering.

Turning a standard cabinet on it's side will increase the vertical dispersion and decrease horizontal, combing will still take place but in a much narrower field. The cabinets that are "turned on their sides" are designed with horn dispersion for that in mind. Some cabinets have rotatable horns for just this purpose. Look at it as a car head light that is focused to give a short vertical dispersion of light and a wide horizontal dispersion. Turning that light on it's side will simply give you light coverage in a narrow horizontal strip covering a much larger vertical area. This will have a detrimental effect on the sound coverage for a large area.

By "splaying" the cabinets you reduce the overlap of the dispersion from each horn at close range which reduces combing!

Line array cabinets are designed for that purpose and each cabinet is specifically focused to a particular listening area. Line arrays are setup in multiple arrays to cover the entire listening audience, Some line array cabinets are individually focused, in as you look at the array it is "bent" or "curved" allowing each cabinet to "focus" on a particular area of the audience. Others maybe a straight line but each driver in those cabinets are focusable both in the horizontal and verical plane.

Many arrays are now going to ribbon drivers for their horns and that is a totally different beast!
 
my question is,,, if it is a Karaoke set up... really, do they even need that much? The tent didn't look that big...

I did a gig in a tent for UVA once, the tent was 70 feet wide and 350 long pretty much covered the entire football playing field!

I used 4 218s, 2 215s 4 210s with 20,000 watts of power for that gig
