I think your best bet would be to go for the K...But...there are some other good choices.
Elemental Designs K-Series- In my opinion the best sub for the $$ that i have ever come
across. They are $135 and perform much, much better than
they are priced. I have no complaints whatsoever with mine
so far..Not to mention Elementals service is top-notch.
Alpine Type R- very nice daily driver sub...hits hard, and sounds nice..Alpine quality as well.
Pioneer Pro-Series (i think thats the name)- can be had cheap on
Ebay, and are a good
bang for the buck.
Audiobahn-if you want a cheap sub that can put out some decent SPL, while sacrificing
some SQ, the lower level audiobahns are for you.
Shiva- never heard one personally so i cant tell ya, but from what i can gather, a good
sub that needs a pretty decent size box to operate well, as it can also be used for
home applications.
There are several other subs, but those are some that came to mind off the top of my head. I would like to reinterate that I would say spend the extra $$ and get the K, they have an excellent mix of SQ/SPL and they are a very versitile driver. They can also operate in some really low volume enclosures. But...I run K's so im a bit biased. //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif
