The K series is good for dual sub ported applications, and it's fairly cheap, and the Kx series is untouchable for the money (2 for ~$135). The high excursion A series is awesome also, but expect to pay a premium $280 for a 12"...if they are as good as they say they are, it might be worth it. I will be trying these when I get subs.
