Actually I was going to hold off for a while. Doing this initial purchase of AVR, fronts, center, and surround was going to be enough for now. I was planning on then trying to figure out what kind of sub I want, and yeah that will be really important for me too actually. I don't just want any run of the mill sub, I want something that I will be able to feel, something that will rumble my house during movies, but will still sound clear for music. Hmm what do you think that equates to? What all should I look out for, size and power wise? Do you like your polk sub that's in your signature?
