GX5

#1 Post by matty-smith »

Hi Everyone,

Im planning on building 4 Tuba 30's Loaded with 3012lf's

The idea is that i can take two to some gigs and 4 to others and use the same amp.
Im planning on using a QSC GX5 amp which does 500w/8ohms or 700w/4 Ohms
Is this possible, As somewhere on the forums i saw that you should only run 300 watts into the 3012lfs

Also im planning on buying a DBX Driverack PA+ any reason why i shouldnt?

the 3012lf is limited to 50 volts as per the plans. the gx 5 probably puts out about 52 volts at 4 ohms I believe? with some work from the drpa you will be fine. Limiting is good. I dont expect you will be running them WOT all the time either, and you've got a couple volts of extra space for overhead.
Built:
2x Tuba 30s delta12lf loaded (gone)
4x Otop12 d2512 loaded
8x t48s (18, 18, 24, 24, 30, 30) 3015lf loaded
2x AT (1 mcm, 1 gto 804)
2x SLA Pro (dayton pa6, 6 goldwood piezo loaded)
1x bastard XF208

2x OT212 (delta pro 450a loaded, eminence psd)
