I have the MPAK 6, set it up per instructions and set amp up so I thought it was distortion free. Went on a long ride (400miles) this weekend in heavy rain and both speakers took a dump on me. I'm waiting to hear back from ARC what they think the issue is or if they will warranty them since I didn't buy them through one of their brick and mortar or authorized retailers. (Got them through Phat Performance Parts.com) They look liked they be a hell of a good and sturdy speaker, heavy magnet, carbon mesh cone and adjustable tweeter dome. Word of advice if you do buy the system, when adjusting the amp settings unscrew the top panel to access the pots. They don't align perfectly with the top holes and are fragile, soft plastic that will round out or break with too much screw driver pressure. Hope this helps some. Best of luck.
