well not so much a build log as it is the finished results. :) i forgot to take pictures along the way. i was to busy and having to much fun to remember to take pics.

well anyway its a 31" tall by 17.5" deep by 15" wide sealed box with a double baffle front. no internal bracing, figured the double baffle would suffice. it's 3.32 net sealed with 52 oz of poly-fil.

i am using the o-audio 500 watt bash plate amp on the 16hz sub-sonic/EQ setting. the shiva-x will be here Tuesday (i can't wait) but for now i am using a jbl driver that came out of one of these. http://jbl.com/home/products/product_detail.aspx?prod=P12SW&Language=ENG&Country=US&Region=USA&cat=SUB&ser=PER

she sounds great right now until you push it hard on the low notes. the little jbl just doesn't have enough linear excursion(xmax).

here is the in room response at the main listening position.

she's **** flat for a sealed box. +/- 4db from 12hz up to 100hz where i sit!

this is how the shiva-x models up in 3.32 net sealed.

i'm not sure how the current jbl driver models up in winisd because i don't have any specs on it. i'm hoping for very similar results, just with the ability to play the low notes without sounding like a mess.

snapped a quick pic of the box as it sits right now.

not sure how or when i'll cover it. looks aren't as important to me as the sound.

i will update once again on tuesday night after i get the shiva-x in the box.

well its tuesday night and i promised an update.

the sub is f'ed up apparently. once it moves a half inch or farther it makes a very audible scratching sound. seems to me that the coil is out of alignment. the box it came in, the packaging inside the box, and the sub itself all look perfect though. so it looks like we can't blame the shipping company.

i sent them an email but i'll be calling them in the morning. what ***** is that it took 9 days to get this thing and i will not wait another 9-10 days. i'm gonna try to get them to send me a replacement 2nd day air.

to update this thread; i got the shiva-x, but it is defective. seems to be a mis-aligned coil. good news is that it's response it pretty sick. its only 2db down at 12hz. :) pretty sick. DIYcable sent me out another replacement. i noticed the scratching coil when playing pink noise so it's pretty bad.

Good for you. Many folks don't really know just how much effect the room has on response. Just watch the power you throw that thing now that you have it EQ'd..

even with the EQ'ing i should still be able to run her pretty **** hard. i guess xmech on it is 35mm. but from what i heard this sub is a bottomless design. it is suspension limited.

this is with the full 500 watts on it.
