You do ship to Canada, and very promptly. I was very pleased to see that brokerage, duties and taxes were just as you had quoted. Bravo!

FLI Underground Performance
Getting the most bang for your buck has never been easier. The new FLI Underground line of speakers offers great full range sound for an affordable price. These entry level speakers are a excellent choice for factory replacement speakers, as well as speakers that are powered directly off an aftermarket audio receiver. They feature a electroplated injection molded polypropylene (IMPP) cone that delivers fast and articulate bass. The PEI tweeter and midrange combine to produce outstanding high frequency response. The butyl rubber surround delivers an improved lower frequency. All of these things join together to create a full range sound that is comparable to speakers two to three times the price. For those looking to a cost effective way to get some higher end audio, the FLI Underground speakers are the ideal solution.

I put these in the rear deck of the 2008 G6, powered by a PBR300X4 amp. They sound surprisingly good for the price, good tight bass, decent highs. We'll have to see how long they last at 75W RMS.
