I currently have the Mythos II and Mythos III next to my pioneer elite, I am interested in buying a subwoofer to go with this set up, my room is not big at all, I am sitting about 10' from the set up, I was looking at the supercube II and supercube I, I think, one was like 1500 watts or something like that, I could get a smoking deal on one of those, my questions is the following, is the supercube I overkill for a small room? also how low (frequenzy) should I set my sub? thank you for your help.
