Its Xmas time & My Merlin TSM-M Woofer is blown

What a christmas... No Tsm-M?? I have been raving about my sound system to all of my family and friend and one of my tsm-m woofer are blown. All of them will be at my house on christmas. Everytime it plays a low note it blaaaas and blaaaas... I grew up and work in a part of town where people do not know what audiophile mean( New Orleans). They think hi fidelity is Bose or infinity. I am not going to be able to justify spending this kind of money on a system that can't play. When some one ask me to turn on the music. How can I tell them, one of the speakers are blown. The puzzling thing is I do not listen to my music at high level. My Tsm-m's are 2 years old and uses the MW 164 pulp cone woofer. Can I replace the (MW 164) woofer with another (MW 164) woofer. Will there be an audible difference in the sound quality. Is there a solution for this madness? Please help!!!
My system consist of:

Speakers= Merlin TSM-M,
integrated amp= DK design MK II,
Cd Player=YBA integre cd player,
speakers cables= audioquest forest,
interconnects= aural thrill air golds interconnects

A Decent start up system
