Problem with my Pro 80's

I have already emailed Tim at wetsounds regarding this problem but they are closed till Monday. Below is the email I sent and was wanting to know if others have had semilar issues? Is this as simple as a lose wire in the internal wiring harness:

"I purchased all new wetsound speakers for my boat last season (tower and cabin) and they rocked. After the last day out I pulled my Pro 80's down and stored them inside my house so no one would steal them. Today was my first day going back out and when I hooked up the pro 80's one of the speakers only seams to be playing the horn, no mid bass. When you touch the outer speaker you can't feel it vibrate and only sound coming from horn. I disconnected and switched it with the other one to see if it was a wiring problem and found out it was not. What do you think is the problem? All help would be greatly appreciated."
