I would like to add just a few details. First, it's not super difficult to develop a decent 3-way. There are a bajillion of them ut there, and some are pretty good. The problem comes when you want to keep the price under $3,000 and still provide truly deep bass extension with a woofer that won't require a cabinet the size of Cleveland. That's what has delayed this project and has generated countless e-mails. We struggled for almost a year with a woofer that had admirable characteristics down low, but that lacked output in the critical midbass range. In the meantime, I was following glowing reviews on DIY boards about a premium woofer manufactured by SB Acoustics under the name Satori. SB Acoustics was started by former engineers of Scan Speak, and I've used their 6.5" woofer in a previous version of my Philharmonitor. The new line is modeled after the Uber-Expensive Scan Speak Illuminator woofers, one of which Jim has used in the Silk monitor. The 7.5" version promised everything we were looking for, and that's what Jim will be bringing to Chicago. I personally think the Salk Satori would be a good name if the folks at SB Acoustics would allow it.
