Quoted from metallik:Before there was Pinwoofer, before Flipper Fidelity, before even PinballPro, there was the original DIY: my amplified AFM that I hauled to Expo 20 years ago.
There was nothing else like it... you could hear martians dying clear across the hall. Most people really enjoyed it and I brought it back for a couple more Expos. This is the game that started the trend for better pinball audio. I documented the build on RGP for others to use, and later did my Demo Man and STTNG. Eventually PinballPro came out with their original unamplified kits, and the pinball audio aftermarket was born. The AFM upgrade still works great!

Thanks @metallik. I have your design on my AFM since way back and it works great. There is so much added bass that it feels like a shaker motor.
Also put this on my Congo and the drum track is amazing. Hopefully the current owner is still enjoying it.
I have a couple more amps/speaker sets to eventually upgrade Shadow and TZ.
