4-way active PA. Techno system! Build thread
I will make this my build thread for my DIY 4 way active PA.
The anchor of the system will be my designed PAL12 tapped horn subs.
The system will consist of:
(2) PAL12 subwoofers 30-100hz (Eminence LAB 12)
(2) Double 15" super compact midbass 100-500Hz (celestion 15" ts-be-15300)
(4) 8" sealed back midrange 500-2000ish maybe 2200Hz (Eminence Alpha 8a)
(2) 10" round horn waveguides, 1" compression drivers. 2000hz or 2200hz and up (18 sound ND1070)
QSC RMX 4050HD
QSC RMX 1450
QSC RMX 850
DBX driverack 260 (4 way mono)
8c 13awg wire for each left and right, will make setup super easy.
All Neutrik Speakon connectors
There are very limited size restrictions (for transport purposes) hence the undersized midbass (and no horns booo!)
Got one midbass almost complete.
Might add a little more 18mm bracing
How come you're not doing an all horn system?
Size restrictions. Believe me I'd love to. Maybe in the future if I get a big van to transport. But for now this will be the absolute largest that I can fit
The reason for my size restrictions. Need to fit everything into a 2012 CT200h :0
Firs pt midbass 90% complete
White duratex for the midbass cabinets is on its way. Need to mount to drivers and the heavy duty grills Also need to mount the speaker pole hats in the top of the enclosure.
This is the way I plan to run the cabinets tapped horn turned down on its side for the base, then the midbass standing up
Quick pic after I dragged both subs out to test fit in the car....
Got started on the second midbass as well.
great :) keep it coming
Yeah, really interesting stuff! keep em comming and we URGE to hear your comments on SQ/SPL with music!
The system below, (also using Lab 12s for LF in a similar size cabinet as the Pal plus waveguides), uses a speaker cord box as a stand to elevate the top cabinets (containing one 10", two 6.5", and two HF drivers) to 67.5 inches high. The cabinets use interlocking dowel pins and ratchet straps to secure the tall system against the crowd and wind.
People can stand only a few feet in front of the system and not hurt their ears, and without the HF being absorbed by them, it carries much further.
The whole system fits in a small trailer, avoiding abusing the interior of my Mustang.
Building the trailer was a lot easier than building any of the cabinets...
