8 ohm Ampeg 610 HLF

Hey I wanted to let it be somewhere on the internet since I wasnt able to find it, I found a way to wire my 6x10 cab with 6 ohm drivers to run at 8 ohms. I had dreams of running it alongside another 8 ohm 4x10 off a pf500 and I achieved it today.

They come from the factory wired in series parallel, basically 3 pairs of 2x10s(in series) and then all those wired in parallel. The drivers are 6 ohms, with this wiring configuration, ends up at a 4 ohm load.

The tricky part of this is that its a ported cabinet. The shelves inbetween each section have 2 6in holes drilled in them. It makes it a pain to swap in 4 810 drivers in the top cause you have to seal it off the bottom shelf so it doesnt reach the ported section at the bottom.

If you were wanting to use that bottom ported section, you must use the stock 6 ohm drivers in all 6 speaker slots with no obstructions or else the air pressure will get messed up and youll blow your drivers.

HERES THE SECRET!
I found that if you wire up 2 stacks of 310s in series parallel with 6 ohm drivers, that gives you a 9 ohm load! Not exactly 8, but in most cases youll be fine and it will work.
