O.K. here are some Pic's of 2 of the 4 different enclosures I'm going to try out for a MTM Monitor using the SS8530-K00 Woofers and the Vifa XT25Dual Concentric Tweeter, the idea is to have separate enclosures with the tweeter suspended in between (off-set or aligned) Minimum baffle area and completely adjustable for-aft and up down, once I get the spacing and alignment the way I like I'll permanently fix them together, If any of you would like to let me borrow some measurement software I'll buy a calibrated Mic and post the different results for the different enclosures, or the other way around I'll buy the Software if some one will loan me a calibrated Mic, unfortunately I can't afford both right now, as you can see I'm spend a lot of money and time on this crazy enclosure experiment.
Have I gone too far, are the DIY worms eating my brain?

  A multi layer of fiberglass and composites especially designed to dampen vibrations, with a gel coat finish, just like a boat finish.

    Did you build these up yourself, or are they from US Enclosures? I have a pair of Tannoy System 600's with the 6.5" dual-concentrics that I'm eventually indending to build into some spheres, but haven't really thought about how difficult laying up my own composite structure would be. Any stories/tips surrounding what you did would be appreciated.

      Good eye, the Sphere was built by US Enclosures this particular one is a 12” with just over 10 Liters with dual ports that fire forward, so far the preliminary listening tests are very impressive compared to the other wood (MDF) enclosures I’ve built at 8.28 Liters and 10 liters. I believe there is definitely something to these sphere shapes, but only measurements could prove this along with extensive listening and comparison to the other styles, which is what I hope to do. In addition, this Sphere only cost $75 plus shipping which isn’t bad.

        That is a very reasonable price. I made my own spheres and if I had it to do over I would not even think about trying this at home. They turned out pretty good, but it was an enormous amount of work.
        The best thing about the spherical shape is the outside creates a smooth baffle step rolloff. The bad thing is that on the inside it is impossible to control the huge resonant peak based on the diameter. I was not able to tame this problem until I effected a change to the internal shape.
