okay i have a dual 12" qlogic type 4 bandpass box.. i know its not the smartest idea but i want to run it anyway. i have a memphis class d 500 watt amp and dont know what subs to get the only subs i found that are made for a type 4 bandpass are polk audio ex124's which im not sure because i havent read any reviews. I was wondering if anyone knows what kind of subs i can get to fit this box or ones that will work great for a decent price. any ideas or should i just go with the polk here are the specs of the polk...
The ultra-stiff mineral-filled polymer composite cones with rubber surrounds featured on the Polk Audio EX124 subs deliver what Polk likes to call "skull-collapsing" bass. The vented pole piece keeps the voice coil cool, for reliable operation.
These surprisingly affordable 12" subs can produce clean, powerful bass from ported, sealed or bandpass enclosures. If you're a do-it-yourself box builder, you will love the specs and tips Polk includes in the owner's manual. 1-year warranty.
