Adire SHIVA Cabinet Internals

My Shiva enclosures were designed to be about a Q=0.65, or about a 17" cube of available volume per driver, with one driver per enclosure. My bracing ideas for these drivers was that stronger is better. I went with an interlocking design which is pretty neat looking. It's too bad all this work is inside the enclosure, never to be seen again. I also designed the bracing so that if I were to decide to get a passive radiator from Adire, I could somewhat easily modify this enclosure to work, thus the large cutouts on the rear of the bracing. The final listening result in my 21,000 cubic foot listening environment (very large room with 14 foot ceilings and 8 foot wide hallways connecting 4 common areas) is very strong bass up to my 'demonstration' level. I'm currently driving my two Shiva with a modified Hafler DH-500. Each Shiva has the VC's in parallel and is recieving one side of the amp output. I wouldn't change a thing during the construction of these enclosures personally, but I'm sure an experienced woodworker will see a lot of imporvement possibilities.

 In the pictures below you can see how the different panels slide into one another, creating a VERY strong brace per enclosure. I simply glued the pieces together. Once these subassemblies (Pic 9) are glued into the 3/4" MDF 20" cube, each enclosure weighs about 50 pounds. Both the front and rear baffles are 2 pieces of 3/4" MDF laminated as you can see in Pics 2 and 3.
