Small PA system setup for band help

Post by Dado » Fri Sep 15, 2023 1:24 am

A few friends and I starting playing again on a regular basis just for fun. So I dusted of my old pa equipment.
Peavy MD3 mixer
Amp Sonetic Labs SA650 (same as a QSC USA1300) for FH1 speakers
Amp Crown CTs 600 for SP3 speakers
DOD 835 crossover.
2 Peavey SP3 speakers (8 ohm,150 continuous/300 program watts)
2 Peavey FH1 speakers (8 ohm, 350 continuous/700 program watts)
All this equipment was bought new in the early 90's less the crown amp. I just picked up used somewhere.
Used it a couple times and blew the speakers.
I put in new baskets and 22a drivers.
My question is how should I set the crossover for each set of speakers?

Couple of "If's" here but if the subs are right below the SP3's and you want to be using the tops to keep up with the subs I'd use a 150hz crossover point. This will free up the tops to operate in an easier frequency range. I ran SP2's and FH-1's in the late 80's early nineties for some time and used the PL-150hz crossover cans with very good results. Remember the FH-1's are more of a low frequency enclosure designed to run from 58hz up to 250hz or higher used in the SP1 setup. I'd use at least a 40hz low cut if one is available on the crossover on the FH-1's.
