Hi, I am new here and dont know a lot about audio equipment. However, i am planning to build a small gaming room. For the sound system, i am thinking about using the Onkyo ht-s550 htib. I have read a lot about the system, and heard good reviews. However, i did notice that the subwoofer had problems. Also, the subwoofer is only 120 watts, which isn't that great. Since the system is actually just a receiver with a set of speakers, would it be okay to connect a powered sub to the receiver? I am thinking of buying a Bic-f12. Would this sub blend with the system, or would it be an over kill, and would it work with the system in the first place? Thanks for all the help in advance!
