Aaand yet another Shiva-X thread... DUAL!

Hello all! This thread is to show my limited DIY skills to all you out there. I have had project ongoing for whole springtime here in Finland meaning 1.1.2009 all the way to date. Project is almost done so pretty much all the flaws you see in my design cannot be corrected! :bigsmile: I have quite a patch of pictures and I will upload all of them soon but here is the intro. Hope you enjoy! :neener:

Introduction:
Enclosure: 115 liter sealed sonotube (4,06 ft^3)
Drivers: Two Exodus Audio Shiva-X both in the same sonotube opposing ends.
Amplification: The T.AMP TA2400 [~1x2000W continous 8ohm)

Pre-project thoughts:
Why sealed. Because I have had many different flavours of vented subs last one being CSS SD12 @ 120 liter tuned to 18Hz. SD12 was excellent at movies but it lacked the musicality somewhat... So therefore I took the route to build sealed for these reasons:

Pros:
+ Group delay very low across the whole frequency range
+ Phase response more even
+ Ultra low frequencies do not *CRITICAL HIT* the sub so badly compared to vented --> no HPF to add delays of any kind.
+ Frequence response rolloff better suited for massive room gains at lower end.
+ Subs 1m apart from each other vertically. Might do something to those bad standing waves which are room generated between floor and ceiling. Dunno, just a theory....
+ I wanted to build something! :R
Cons:
- SPL lower to vented --> dual sub needed to achieve same SPL (and more) as my former CSS SD12 vented.

Unibox simulations:





As you can see from the pictures this enclosure is very tight fit for two Shiva-X. Can not go much smaller than this, eh! :whistling: Power requirements are ofc higher in smaller box but I can afford it. Here are couple more pictures but remember WORK IN PROGRESS! :foottap:

Feet are *NOT* going to end up looking like that! I am going to cut them so only 6cm chrome tube is left. I just quickly threw the tube on footplate and chromefeet and it barely stood there while I took the pics! :nerd:

So, I really appreciate all the input you give. I try to update this thread as soon as I have time. Pretty wild week ahead of me but hang in there people.
