    These speakers are designed for surround sound and that is where they work the best. When bought on sale you get a good deal. Watch when purchasing online, they get shipped Canada Post Expedited and in my case, they sat in the local mail depot for 5 days counting Saturday and Sunday(I have to live those two days so they count). I filed a complaint at 5pm, and at 6pm there was a knock on the door, it was my old regular carrier from a couple of years ago, he said he had seen the box for a couple of days just sitting there. He asked my current carrier why was he not taking the box, current carrier said it was too heavy. Just a warning that if BestBuy is going to continue shipping this single box using Canada Post it may get ignored by the carrier. With all that being said, the box was heavy. And the sub speaker uses a standard RCA cable that is readily available in just about any store that sells audio or computer hardware.
