Quoted from Underspin:Initially I didn't like TF at all. Years later a friend (Pinsider nerbflong) got the machine and put one of his famous thunder subs under the cab. Now it's one of my favorites to play when I'm over there. And it was him that also got me hooked on Star Trek. Same thunder sub...his house shaking during play. Great sound on that machine so I had to go get one of my own!
Funny....Initially I didn't like the sound on my transformers, upgraded speakers and now it's my favorite sound package in all of pinball. Never thought sound was really important until I started collecting. Now besides for gameplay, it's sound for me. A game that has great sound to work with the gameplay is what does it for me. Try playing your favorite game with the volume off, not so fun anymore...or atleast not in mho.
