def not louder than dd but a nice sub for the price nonetheless especially when on a budget cant beat it

   DJFaB From california

this sub has the ability to pound for days without getting warm, i have two of them on the opti 6000d amp being beatten daily.  the only thing i would of wished for is for lanzar to sell the recone kit for it,  the spider on this sub is not so great being small in diameter not allowing it for full excursion.  that being said is the reason for the frequency being high starting at 50htz and up.  flat wire on 3" coil  looks to be only single layer with a very tight gap making the motor/magnet  to only accept a thin coil if trying to rebuild the sub again.  yes im having a hard time trying to rebuild mine, and i love these dang subs very underrated. might even look into machining the gap to accept a bigger coil just to get them back into my trunk. sucks that there on backorder on any online store that i look for.
