Well, okay, its not a wall.. But it is a stack of woofers. I'm currently packing up everything for a move and started making a pile.
I love bass. So I have a subwoofer on every single machine. Yes, I know there are ways to hook up multiple games to one sub. Its hard not to know. However, I feel multiple games on a sub muddy the sound and I like to fine tune a game and subwoofer with gain and crossover. Certain games do better with different subwoofers. So with a bit of trial and error I try to match a sub with pinball.
Yes, its crazy, extreme. That's how I like it! Now I just need to figure out how to hook them all up to Metallica!!
