Just wondering if anyone has been using any cardioid sub setups in venues that are right around the 500cap mark? I have EV QRX 153s over JBL SRX 728s. When I only need 1 top per side I simply put one 728 on end, 153 on top. When I do not need more low end but I need more coverage I find myself bringing 2 subs per side for the sole purpose of getting the tops high enough. Now I understand there are several other options to get the tops higher, I can fly them but too much hassle for most of these venues even if I bring my own lifts, I dont want to invest in scaffolding or any such to lift them up, and I dont want to build cable trunks that double as extra height for the speakers, none of that is the question. Keep in mind that my overall goal is sound quality for live events. I want to setup my systems in the most professional manor I can, I strive for safety, neatness and the best sound I can get from each and every element of the system.
Are there any benefits to running cardioid subs in a smaller venue? I am not fighting any serious issues or any extreme build up of low end up the stages very often, and I never mind having more sub that I need, but If I can benefit then Id love to try it, if anything just to learn.
If there is a benefit, how would one go about setting this properly so it doesn't actually cause more damage than help? I usually see blocks of 3, two subs forward and one sub backward. Is it still possible with only two subs per side? What are the thoughts and opinions of people who use cardioid subs a lot more than me? Any links and such about cardioid subs are welcomed too, I know there are a ton plus Dave Rat has some videos and what not.
