I just do this with 8 or more Quakes....
Instant cardoid controlled sub. You could have a conversation behind them quite happily while FOH was getting some serious bass pressure! |

Nice set-up Mike, what mid highs were you running? Were they in stereo each side?

How does this works out with horn coupling & mouth area?
If I reverse 2 in a stack of 6 bandpasshorns (bph) will the reversed box uncouple? If I do end fire distance have to be kept big enough not to "stuff" horn mouth (negative expansion). I guess end fire could make rear horns see a bigger horn or a corner, front stack is delayed to couple. I can't really figure out what happens to 2 reversed boxes and the horn coupling? Will it overexcurt fron cancelation or the opposite couple the delayed half wave from front? I'm a little worried about this, no drivers to waste. |

Sorry for dragging up an old thread but I think most of the contributors are still active members.
I am starting to get into sub arrays and am looking to do a simple set up for a gig in a couple of weeks My aim is to reduce bass behind the speakers as there are premises quite close by. The venue is a big tent. I will be using three 18” reflex subs each side of the stage (this is the only config available because of the venue set-up) So… flip the centre sub, reverse its polarity and delay it by the distance between the rear driver and the drivers in front. Is this it or have I missed something? (Seems too simple!) Cheers all

The easy way... Nexo CD18, or if your budget is low'ish, Nexo CD12.
CD18 is a mean piece of kit! But you need some hands to throw them around. Big Box with Big Sound! CD12 on the other hand.. That is a fun little box which pack quite a good punch without being fridge sized

K.I.S.S........DSP and Digital Mixers have allowed for so much more adjustment then ever before.......Maybe too much...A Friend does Sound and uses EVERY button of his gear...Time delay the Drums to the mains, Gates, Compressor, EQ, Effects on every channel...Some rear facing subs...etc, etc, sounded like Dog Shit.....I went to one of His Shows and turned off most of that stuff...Used Gates on Drums, 2;1 Compressor on Vocals, and a very small amount of EQ and Reverb on Vocals....WOW! His system delivered cranking Sound....He was over Thinking Sound....Sometimes K.I.S.S. is the Best.....

I'm going for it being an acronym for keep it simple stupid. Or maybe he was listening to the hair metal band. Either way very helpful lol

I understand what KISS means and I completely agree with you regards to keeping the signal chain clean etc. but this is not what I'm suggesting here. I'm looking to set-up cardioid subs to mitigate/reduce a possible noise complaint issue, not because I think it's fashionable ;)
