Woke up this morning to the sound of a drip and it turns out the severe storms of last night caused a roof in my ceiling... right over my entertainment center of all places.

My main TV, receiver and everything else was spared thanks to the speaker shelf over my TV. However my front and center speakers are now "warped." No water got inside the speakers but the damage to the wood finish isn't very pretty. Anyone know if this can damage the sound of my speakers and know if there's any way of saving them? I was thinking since these Polk RTi's are real wood finish maybe I can sand them down and re-paint them. Any ideas Big Daddy?
I might just accelerate plans to buy new fronts and a center that I wasn't going to do till later in the year and retire these speakers to another room.
