2 T60s vs 6 tops

[pond]

Hardly a fair fight, the T60s easily kept up with 3 sets of PAs. Eventually we had the tops placed so they were pointing in all directions.

Initially, we had everything going, 2 JBL 15" Eon powered PAs, 2 Yamaha S115Vs, and 2 EV ELX112Ps all playing >102Hz, with the T60s handling <102Hz. I thought it sounded like shit, the JBLs and the Yamahas were just so 'blaring' and shrill.. I kept walking around and hearing how bad things sounded and turning the volume down, but the other stupid Dj kept cranking it back up. The only area that sounded good was in front of the EVs. Then the cops came and said we had to turn it down, so we killed all but the EVs, and I felt it was a huge improvement in the sound.

So yeah, I need some DRs..

Combining three sets of PA tops is a recipe for disaster. Especially when no attempt at all was made to make them couple. When the three sets are different, you have a whole other set of problems to contend with.

I have a pair of Yamahas (SMs, different shape but same cabinet for the most part) and they sound quite good when used properly and EQ'd. I'm sure the DRs are better, but you really can't hold it against the speakers when the setup is positively wrong from the start.

I hope you don't take offense -- I don't mean any. You're absolutely right, though. This wasn't a fair fight.

Nice, thanks for sharing. How would you describe the T60s at this event? Was anything shaking, or were they polite and present?

What do you mean 'couple'? They were daisy chained so they were playing the same content.

I'd say juuuuuust right. You only get the chest-shaking feeling standing right in front of them, being outdoors and all, but they sounded good no matter where you were standing.

Their acoustic centers less than 1 wavelength apart unless vertically stacked. 1 wavelength @2kHz is 6 inches, so acoustically coupling them was impossible. What you had there was a comb filtering machine.

Glad the event went well. As for the tops as you learned as you dropped some out, sometimes less is more, especially when mixing and matching.

So he didn't get the comb filtering memo, no loss of life occurred, onward and upward.

Anyway. the picture was taken while we were still setting up. The final resting place of the JBLs was on the ground directly in front of and beneath the EVs, which were on the lowest setting my speaker stands would go to, and the Yamahas were on stands behind the EVs, firing 180* away. Is that setup going to subject to bad comb filtering? What would be the optimal setup given a grab-bag of tops?

What would be the optimal setup given a grab-bag of tops?

Vertically stacked, rotated if required to expand the coverage zone, creating a vertical spiral array.

[SirNickity]

What problem are you trying to solve? Not enough output? Or 360-degree coverage? Or both?

What would be the optimal setup given a grab-bag of tops?

Sell two or four to fund four otops, while keeping the minimum tops needed until otops are done. Once otops are done, running two otops per side.

No, but really, get rid of the crap and build something decent. I built two 212 otops at his stupid request because he though single loaded otops would not be enough. To this day, he has never pushed the dual cabs anywhere near their limit and regrets having request the dual loaded cabs as 80% of the time a pair of single loaded tops is what he would need.

To be fair he does have a point...

Doesn't matter though, you did what you did and have learned from it so it's all good.

are those the dual or lab 15 loaded?
