If you can't plug the sub into the same surge protector where your other equipment is plugged, I suppose it would be fine. Keep in mind that plugging your sub into a different circuit (NOT just a different outlet. A different outlet may, or MAY NOT be on the same circuit), can allow for the possibility of 60 Hz ground loop hum. Should that occur, a cheater plug (3 prong to 2 prong AC adapter) can usually solve the problem.
If you feel you have to have it, don't pay $89 CAD for it, unless this web site
doesn't ship to Canada, or the shipping, duties, and taxes take it over that amount. $29 US converts to around $36 CAD. If you'll do a web search under "Monster MP SW200" you may find and even better price.
