Find a good shop and go from there. I like the guys at the shop in Roanoke, they know what they sell. Movie sound seems to be more about balance amongst all the speakers, but I never got into it that much.

Ha!
I didn't have room for it, but we just got rid of

(4) EAW KF-300 bi-ampable tops
(2) EAW SB-330 18" driver subs
(2) EAW JF-100 (mid-size center fill cabinets)
(2) EAW JF-80 (nice monitors)
QSC tri-amp rack & processor, 14,000 watts total power
plus a handful of other amps, smallest was 500w/ch, biggest was 2.4Kw/ch
all the speakon cable to set it all up
All the speakers & amps were in road cases, too.

I was a sad boy.

To the good, all that was replaced with
(6) powered EV ELX115P cabinets (1000w each)
(2) EV ELX118P powered subs (700w each)
and for slightly larger spaces
(6) JBL VRX932 line array tops (1600w low, 150w high)
(2) JBL VRX918SP subs (1500w each)

The ElectroVoice products surprised me; they didn't used to make nice stuff.
And the JBL line array is just happy-making.

With the powered cabinets, all my outs can run up my digital snake (64x16 channels, on a single piece of CAT6 cable), instead of having to run NL-4 12ga all over the place.

I'm sure there's some audiophiles out there that will tell me how much JBL sucks.
What-the-fuck-ever.

I may have missed it, but what do you do?


I am a 20+ year veteran of live sound production. EV has always made great stuff, on the high end, but I'll agree their entry level stuff was not that great.

What digital snake? Behringer stuff? I'm a fan of the X32 products. for the price it can't be beat.

getting 2 subs instead of 1 big one just doesn't work that way.
you won't notice it until you move through the space, but 2 subs placed (let's say) 10 feet apart create a comb interference pattern.

I read the engineering documents from Meyer Sound, I didn't read it on the internet, so I'm probably wrong.

It's true, sorta. If you are outside it's definitely true. Spread those subs and you'll have loud spots and quiet spots radiating out from the 2 sources. When you are indoors, it's a lot more complicated. There's reflections that interact in the same way even if there's only one sub in the room. So 2 subs in a room just creates more reflections, but may not be any worse than just having one sub.

I produce corporate events.
Wondered about your nickname. :)

EV's "cheap" stuff was definitely ... cheap.
Soundcraft snakes, 2 different heads: a 32x12 & a pair of 16x8. Using the snake and the console gets you the ridiculous input count.
Si Expression consoles, 1, 2, and 3.
I'm totally a fan of the iPad software for the Expressions; having a mic on the stage and the entire console in my hand just makes me glad to be alive in this digital age.

I don't get to pick brands; I'm not that high in the corporate food chain.

The interference pattern looked remarkably like the comb interference from improperly placed mics.
Unless you're moving across the sound field, you don't really notice the dips.
In MY typical application, the audience is sitting, not moving.
I'm indoors 99+% of the time.

The Meyer document showed putting the subs 1 behind the other, 3.5 feet center-to-center, delaying the upstage cabinet by 3.1msec & inverting the phase on upstage.
You end up with a cardioid pattern, even more pronounced than if you keep the same physical spacing but delay the downstage cabinet by the same 3.1ms with no phase reverse.
10 feet off the back wall, and my reflection from back there is almost completely gone.

Not that anyone in my audiences will ever notice, but it's the principle of the thing. :)

This guy doesn't need a sub.

If you don't want to select a speaker set based off reviews, then many companies offer free in-home audition. Just send back the ones you don't like.

Oh yeah, cardioid array-ing your subs almost always helps. You are reducing the amount of energy thats available to excite the room by about half, while keeping the same amount (or more) energy going forward into the meat on the seats.

I've done a fair amount of corpy work. Most of my time was spent at a medium-large production company. We had JBl stuff. HLA, Vertec, and now VTX. We use soundcraft VI consoles too. After that I spent a number of years touring. Using whatever crap pa was available, but I carried my own consoles and in-ear system.

Which guy doesn't need a sub? Me??
Like Jim said, everyone needs a sub. Especially me. I probably don't need two 12's in my family room, but a nice 10 will hit the spot.

...meat on the seats...
My friend always referred to the audience as "meat baffles".

There's money in corporate to be sure.

Went to a concert at a small venue with my son.
We were leaning on the bar, behind the FOH audio position.
Small space, utterly preposterous amount of line array in the air.
Opening act, A1 was some old pony-tailed dude, house guy.
The mix sucked. Big Yamaha digital console, I could see his VUs.
Vocals were lost in the instruments, just crap.
And he never came out of the green.

Headliner getting ready; young guy comes over to desk, shakes hands with bitter old guy, old guy walks away.
Guy plugs in thumb drive.
I point it out to my son, and say "THIS audio is gonna rock!"
Sure as shit, the mix was excellent, SPL was significantly higher, he was hitting the red.

I'm a firm believer is "volume is no substitute for talent".
This was just better by leaps and bounds.

Feckin old guy, like so many house "A1"s. Washed up, probably former IATSE loser, pissed at the world.
He sucked.
Good thing he was drinking the entire time, or he might have been able to tell what a shitty job he was doing.

Lol. I've seen that a million times. Most old guys are in the clubs because they can't hack it anywhere else. I've hit "soundguy retirement" and I work for a large church now. Yamaha CL5's and Danley cabinets. Its pretty nice. Its also salary which I've never had before.

OP, if you've got money to spend, look at Danley Sound Labs. They really are as incredible as people say.

Some SHmini's as satellites and a CS30 for sub would be the "budget" option. SM80's and a DTS10 for a step up, or SH50's and a few dts10's for the ultimate.

Of course that would take a lot of space. The SH50's are pro sound cabinets. Pretty large. The mini's are not any bigger than a medium bookshelf speaker though.
