Does doubling your tops make a system louder? ie, I have 1 jbl srx715 per side. Will it go louder if I add more srx 715s a side? I guess my understanding of this maybe wrong from what I have read.
Yes it will be louder. HOWEVER the cabinets will start to interfere with each other-especially if they are covering the same area. Google "comb filtering".Does doubling your tops make a system louder? ie, I have 1 jbl srx715 per side. Will it go louder if I add more srx 715s a side?

It is NOT the size of the speaker-but rather the SPACING between drivers AND the FREQ of interest.Doubling your speakers can increase levels,but only to certain frequencies.When speakers couple,it can increase levels.But,as it was explanied to me, speakers only couple up to certain frequencies. For example,18" speakers may couple up to 200hz,15's to 400 hz,12's to 600 hz and 10's to 800hz etc. At a certain higher frequency levels,speaker begin to interfere with each other. I'm sure others can give you a better answer than I can.
If the drivers are close enough together (with respect to freq-1/4 wavelength or less) then you will get a maximum of 6dB addition-assuming you have twice the power available.Well then I guess I was off on that. I thought that a speakers max spl was it. and doubling a speaker wasnt going to make it louder than what that speaker was capable of.

There is another thread here somewhere about using 2 boxes per side but as separate PA systems - eg vocals & guitar through one pair; rest of band through another pair. This does have benefits but won't double your volume either.
In a nutshell, you *can* stack multiple speakers together.
It will be louder.
It will not sound as good.
That's basically the tradeoff people have been making for decades. Clever people with more resources generally can reduce the "it will not sound as good" factor.
