Quoted from Gattiman:
Has anyone played an LE vs Premium and found the upgraded sound system to be a big improvement? I played the pro at a local bar and loved it. Definitely buying it in October/november (in the middle of moving houses right now) but was disappointed with the punch in the speakers. However I have no way of knowing if it was just turned down or the bar I was in drowning it out. Unfortunately in Austin there aren’t any major places to properly try out pinball machines for the home.
I have the LE, which has the larger/better speakers vs the Prem and the Pro I believe. I have it hooked to an external powered sub (Polk 10") and absolutely no complaints about the sound. This thing cranks!
