POLK Audio PRO subwoofer, 8-inch, brand-new !!! in Ottawa, Ontario for sale

I am selling a brand-new subwoofer, model PSW303. It is a high-end sub with a heavier long-throw driver, higher quality internal components (crossover and power supply) and more power that their cheaper entry-level subwoofers. It retails for $600, plus taxes. It has never been used and is sealed in the original manufacturer packaging. I purchased and did not use. I am asking $400 o.b.o
