decent sq subs

I suggest you get two of THESE and a new box.  It's a good deal and you'll get plenty of SQ.

jayson358, you didn't say in this thread how many subs you want to get, but you did insinuate more than one.  And you didn't say if that box you have is cut out for two subs or one.  That info would paint a clearer picture.  But as a generality, you can turn your present box into a sealed version simply by inserting  a perfectly cut piece of MDF into the slot and glueing securely (I recommend Gorilla brand glue, and you can buy that in a small 1 oz. version).  The internal box volume would now include the volume within the port.

I'd like to have one of those Perfects myself.  But I've got champagne tastes with a beer budget.

wondering guys what would be better

mtx t5512-44 12" x 2

kicker comp cvr 12" x 2

alpine type r cvr 12" x 2

eclpise sw-6123.4 12" x 2

now the kickers and mtx's call for ported box @ 38 hz tuned @ 1.7 cu ft

my box is 1.6 cu ft tuned @ 40hz do u think that box is good enough

the type r 's say .75 to 2.0 cu ft port? mines a 1.6 they say 1.7 is best

the eclpise is in its own box

which would be the most accurate, tightest, and deepest out of ya'lls opionion

(and do not say infinity perfect cause their not all that)
