Shiva-X build.....

Shiva-X 12" in a sonosub design. I have a 14" piece of tube and a 16" piece of tube. I can use either. The 14" is 6 feet long and the 16" is 5.5 feet long. I can cut and do whatever I want with either. BASH500 plate amp will drive it, port diameter can be 3", 4" or preferrably 6" because I have a 10-foot length of 6" already!

Any thoughts? I am thinking 150L, tuned to 19hz, 4" port @ 15" long....

Too big for this driver? Too small? If I model it smaller in WinISD, I lose a ton of output at 15-25hz..is this correct?

Porting will depend on what amp you use.

BASH500W or BASH300W...whichever one is most efficient for the build. Trying to go as low as a 12" wil allow.

Re: Shiva-X build.....

6 cu.ft. tuned to 18 hz will get you there. With the Bash 500 HPF changed to 13.9 hz you'll need a pair of 4" flared ports 32" long each.

Re: Shiva-X build.....

I use a Shiva-X in 180L with dual 4" ports. My sub is tuned to 22 Hz, but with room gain it is around 18Hz. It is a nice clean sounding sub.

I am using a pro amp. A nady XA-1100. Using one channel (500 watts). The second channel is being used on a 2.0 CF sealed dual 10" sub.
