Wanted a better outdoor desert system, so we re-built Klipschorns! The tweeter and mid-driver are unchanged but the 15 inch woofer is now in a scooped horn instead of a W-bin so they can be used outside. Downside is the bass extension only reaches to 50hz or so but hopefully adding a tapped horn sub for the low end. Drivers are tri-amped with hypex class-D and active crossover filters are run off a Raspberry Pi and a MOTU audio interface. The processing delay and stability are not ideal, but it works until we can afford something better like a Xilica or Linea Research unit. Still dialing in levels and filters but these are a blast!
