Hey all. Happy early new year!. Yesterday i just ordered the jbl ES250 400 watt sub and i was wondering if this will be enough for home theater. I'll be upgrading from a small yamaha 8" which was horrible!,it was my brothers. I'll be using my new sub with a set of hsu speakers hb-1 mk2 which goes down to 60 hz region. Did i pick a okay sub? and what are your opinions / thought it's not to late and i can cancel my order and pick another sub for more performance for the buck.
