Quoted from Av8:Damn you know your speakers systems. I changed the settings to 4 Ohm and the volume ranges between 25 and 35. I bumped up the gain also. Do you have pictures of your GZ speaker
setup?
Thought you'd never ask
I run Focal 130AC 5.25" coax drivers up front, a Rockford Fosgate Punch 8" 2ohm DVC wired to 4 ohms down the bottom (Qts 0.72), a Pinsound line out converter off the board for a stereo line level output, into a Dayton 2.1ch external amplifier that outputs 50w to the backbone drivers and 100w to the cabinet woofer. The sound is superb. Cabinet shakes to the bass, but the glass doesn't rattle which is good. And negates the need for an external sub (I run a DIY 18" sealed sub for another game )
I printed a spacer ring for the bass driver as it's slightly oversized to the stock hole and didn't want to drill the cabinet. Removed the grill as it's superfluous and can rattle.
The amp also has Bluetooth, so you can use the pinball machine as a bluetooth speaker when not playing which the kids love!
