The Isiris never got it's own build thread, being the culmination of the "Three Way Evil Design Study" - it didn't seem very urgent, as only two pair were expected to be built world wide, due to availability issues with the NS12-513-4A woofer. Of course, that part of the design can be redone with another driver, but that's not what this thread is about. This is about modeling and hopefully eventual modification of my build from the original three way to a four way system with an active low end and a new mid bass/low midrange driver. This got kicked off by some of the discussion in the Unicorn Dreams and Tesseract thread, as this type of four way configuration is at the heart the old Avalon Osiris, the Avalon Sentinel, and the Avalon Tesseract, with various other concepts and acoustical approaches to optimizing power response thrown in. A common thread is an active low end system, and pistonic operation of drivers. Ironically that was also a concept common to the four way system cabinets I gave to Charles Hansen after I got married and they didn't meet WAF criteria at that time.
Text will be added in the near future as time permits this week- go to Post Off Topic to see how things will proceed.
First, to recapitulate the basic details of the Isiris (aka known/named as CA Isis by a good friend in Germany)
