Hey Mac,
Your link features an article on the TCS1061, which is the install version of the TA600 Flex Array. Mention of the FlashLine is in a sidebar article on new product releases at the Pro Light & Sound. It is intended to be a serious competitor at the very highest echelon of our craft.
Flash Line is a 5 way (including all new subs) system. Each 4 way horn loaded line array element contains: (x2) 12" L, (x4) 6.5" LM, (x2) 6.5" HM, (x3) 1.75" HF.
If I could figure out how to attach an image I'd post a spy photo that can be shown now that the release is official :-)
