you been told wrong the prosonic pqr 9962 i had sounded nice but at the end of the day the m90 just plows through it. i have yet to see any boombox that can crank louder and longer with no distress than the m90 , i'm not saying its the best sounding box in the world but it's excellent at doing it's job of being one bad ass motherfarking boombox. to me the definition of the king of the beast farking killers the m90. i love the way it sounds loud in you face and awesome you can crank that somebitch till your ears hurt. i think the most attractive feature is the simple almost a sorta primitive high end look lol. basically battle ship design.
