Just modernizing one of the best midsized speakers of all time wasn't enough, so we decided to give the THIRTY our SUPER treatment with planar magnetic ribbon drivers like our SUPER SEVEN. The ribbons give the SUPER THIRTY quicker and more detailed dynamics to couple with the presence and bass extension provided by the Force BalanceTM woofer system. Amazing for music and medium sized home theater (or as surrounds for large home theaters using the SUPER SEVEN’s for the front speakers!).


  • Medium sized 4 driver, 3 way, multi-chambered acoustic suspension (sealed box) design. Can be floor, stand, cabinet or soffit mounted (can be wall mounted with optional brackets)
  • High efficiency design, allowing it to work with receivers and small amplifiers, as well as providing very high dynamics with larger amplifiers
  • Proprietary Force BalanceTM woofer alignment designed for high output and low distortion
  • 8" planar magnetic ribbon midrange designed for smooth dynamics and high power handling
  • 3" planar magnetic ribbon designed for broad dispersion and solid dynamics
  • Mirror matched cabinets for better imaging (if you prefer symmetrical cabinets, just order two SUPER THIRTY-c's)
  • Dual 5 way binding posts for secure connection of high quality cables, single or bi-wired
  • Available as a finished speaker or as an easily assembled kit
  • Environmentally responsible construction utilizing formaldehyde-free MDF, bamboo fill and green finishing materials
