If you are getting feedback you need to EQ with more precision and agressively. If you are getting paid for the gig and have a feedback issue most likely won't get hired again.
Thanks for the tip, didn’t know that EQ could fix that……….
The thing with the NX985, is the wider pattern of the horn and maybe inconsistency in the dispersion, once you start cutting freq. You loose the bite, the soubd becomes dull, conpared to the ETX-35P
For most gigs ( other than salsa and merengue bands) , I prefer the DBTechnologies Ingenia IG4T, two of these on top of each other, with one or two RCF 8006. Another great thing of these boxes ( IG4T), for little truck space !!
