    Posted: 24 January 2018 at 9:43am
Have an event coming up where we are combining two rigs.

To choose from we have....

-2no, Super bass horn (PD1850 Loaded)
-4no stapier micro scoops (fane ?? loaded)
-4no. cubo 15 ( kappa 15 LF loaded

-2no. cubo kicks

-2no. ASS MX350
-2no. MT101's (kappa pro loaded, awful 1" comp)

amps:
proline 3000
matrix XT5000mf
2no. qsc 1450
1no. qsc 1850hd

2no. Berry ultradrive

The night will be 200+ indoors playing Dubstep, dnb, Bassline, etc.



As we want to use both rigs and want to have max "impact" my thoughts are to stack. Any comments / improvements?

2no. SBH (bridged proline)
4no micro scoops (matrix)
2no cubo kicks (bridged 1850)
2no. ASS (bridged 1450, 1450)

Phase alignment is obviously important and im not 100% sure how to run the subs. 
- Is there a way to align these (no soundcard mic available). Play tone and flip polarity method feasible? What frequency if any would be used.
-Would running SBH 30-60hz and micros 60-110hz be better? By better I mean more 'bass weight'

Overall I just want to run things properly and all input is appreciated.

cheers

That could work. Micro scoops and Cubos behave much like reflex boxes acoustically but you're likely to lose as much as you gain playing them together  so I'd pick one or the other.

No. You need a test rig and several hours to measure and experiment.

No that isn't time alignment and you definitely need time alignment combining horns with reflex boxes.

You need to crack your wallet open and pay for someone who knows how to do it. Like me ;)
