If the system isn't over-powered, how did the woofers and protection circuits get blown? I don't understand that.

Case-in-point: sounds like a gain structuring problem to me. As far as I understand it, the most common failure mode for drivers is over-powering.

I would most likely use a limiter in a case like this. HPF would definitely keep the driver from heating up unnecessisarily, but from what you've described, it doesn't look like that's what caused the failure.

let us know what the amplifiers are... is the system 70v or no?

also if you sending a distorted signal into the amplifiers out of the Samson piece no matter what the levels are you are likely to experience speaker damage.

As far as the one side blowing first... does that side happen to have the shorter length or speaker wire runs?

Somehow I would suspect the real unknown here: the Ipod source. Certainly could have been an mp3 with issues (1 side overloaded with low frequencies, for example), and you would never know it unless you were there.
