I used to be a DJ back in the early 90's...I helped redesign a nite club in Latrobe, PA that had 2 giant wooden W bass boxes under a dance stage. They were kind of like big, flat La Scala's!! We were surprised to see Klipsch 18" woofers behind the access panels when we opened them up. So we sourced out new Klipsch woofers to replace them. Those 2 W boxes rocked hard for many years after the redesign. I was just curious to see if Klipsch actually made these things or if they were DIY with Klipsch woofers? I wish I could track them down today as they were definitely performers!
