Yeah, basically unless you hit the lottery or your just really loaded and feel like blowin some money dont bother looking into it. You can get them off the MTX site I think or an Elite MTX dealer and I think theyre what, $8,000? idk...
if u want to waste 8000 dollars on a sub wen u can get somethin thats louder and sounds better for less than 1000 buck then the jackhammer is perfect for u. i definitely recomend the jackhammer for u. u will be satisfied
