I was dead set on using Shiva X-2s in my setup. However the June ETA date came and went, and now Kevin tells me that his manufacturer is basically non-functional and no eta on when/if new Shivas will be made. So I need to pick between my alternatives (unless you are lookin to sell a 12" Shiva in good condition :p).


Enclosure: 1.5 cu ft sealed fiberglass box (fitted for trunk side, stealth-install style). cutout for 12"

Power: JL Audio HD 750/1

Focus: Sound Quality* >>>> SPL

Uses: Bass and beat heavy music - metal, trance, techo, raggae, hip hop, rap, dubstep, grime and any other name you've got for something that gets low and grimy and fast. BUT ALSO, a lot of prog rock and 'hi-fi' tracks. Think Tool, Pink Floyd, occasional classical music. Needs to handle these and shine doing it.

Front Stage: JL HD 600/4 driving 4x HAT Imagine I61-2 all around. May upgrade to Clarus or L6 setup at some point.

Price difference for the above 3 options is not a consideration.

* What SQ means to me: "low noise floor, inaudible levels of distortion, good tonal accuracy, good dynamics, and good stage/image." (a quote i lifted from another forum that really hit the nail on the head for me). Keeping in mind the application of said sub in terms of music types. Another way I like to define a high-SQ set up is that it has a 'warm' sound... vs harsh. I know that's even worse a term then 'SQ' to begin with, but for anyone who plays bass, its the difference between a Mesa Amp/Cab or possibly a high-end Peavy, vs something like Hartke or even SWG. Played with a Warwick Thumb bass. Hope that makes sense...

Unfortunately you're not going to find another driver comparable to the Shiva-X when it comes to price-to-Xmax (and how flat the BL is within the Xmax rating!). If you wish to purchase a new driver (not used), I would go for the IDQ 12v3. Their Klippel results for the IDQ v3 were very nice.

Good! The Shiva-X's are excellent drivers. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
