Quoted from jgadzia:crazy you spent all that money to have more problems. I have a couple of those kits in my machines and never had an issue. However, I started to learn very quickly that the kits only really sound better because of the better woofer speaker. So my remaining machines (including my Star Wars) I have just added a crossover and a better woofer speaker. Total cost=30-40 bucks and they sound just as good as the pins with the pinball pro speaker system. I highly recommend it for anyone wanting to upgrade their speakers.
I do like the better sound a lot!
I opted for the 50 dollar upgrade the the better woofer.
I like it a lot (really rattles that bsmt2000)!
Only sound issue, is sometimes I think the frequency into the woofer is a little too high....I hear muffly sounding voice out of it that takes away from the otherwise cleaner sound.
Maybe I should have stuck with the regular version and tried that first. I am a person who LOVES bass, but I found I had to turn volume control for backbox speakers all the way up to even start with (to minimize the higher tone muffles coming thru woofer, not because of excess bass!).
Anybody else have an audio opinion on either kit for their SW??
