Yes, this is a variant of the MAS-85 with eight 5.5“ woofers and a BigE designed HF waveguide with a CD in the center. This will also be a powered unit with a passive single 15" subwoofer. The test units we will be using are passive and one uses eight Vifa tweeters the other is using two Ciare tweets. After evaluation we decided to employ a HF waveguide of our own design for the production models. We did have other mains to use as well but an angry Crown XTi4000 blew them up.
