Hey everyone. hope you're all well.
My question is not to complicated but feel free to add onto my idea.

I will be setting up a live rig for an outside event soon and will be ordering in equipment, so far my rough config looks like this:

Mixer -> EQ -> Crossover -> Amps -> ?Speakers?. (Stage monitors are active)

My question is, will having x2 Double 15" speakers and x2 18" Subs be enough for a variety of different acts? Eg: Bass heavy hip hop, DJ mixing house music etc? If not, what would you recommend? The crowd will probably be between 150-300 people.

I've never done a gig this big and have usually used underpowered setups (painful experience) in terrible sounding halls , so any info which will get me the best output possible would be appreciated.

Thanks in advance

 

Lows/Mid Lows frequencies seem to be nice,but what about the other frequencies? You need absolutely for example 2 speakers with 1x12"each, 2 speakers with 2x10" each and 2 tweeters high power

 

Good point, i'll be using a Behringer CX3210 crossover which has 3 bands.

So basically what I can do is use 3 pairs of speakers, 1 for each band correct?

 

I don't know your budget, but I have an Allen & Heath Qu-16 mixer. It boasts beautifully sounding pres, 4 rack effects, flexible routing, 4 mono and 3 stereo outputs, RTA analysis, 31-Band EQ, compressor, gate, and eq in every channel, iPad control, and light weight. The cheapest ones without a fader rack will cost less than $1500 street. With the faders and onbaord controls it goes for around $2000, even less. That's all you need except for powered speakers.

 

Ahh having a mixer like that would be nice, unfortunately i'll be hiring all of this equipment on behalf of a client. The nearest audio shop only has very basic equipment in their stocklist. I'll definitely consider a system like that if I were to go slightly bigger.

 

If I were you,I would take 12" speakers for Mid range instead of 15",if you have only 2x3 speakers.That would be better,if not you won't have good mediums,only low and high frequencies.
