Hello All, I am building my HT. I am looking at buying HK7200 for my reciever. I am also thinking of going only for a stereo system right now with the two fronts. Maybe over a years period, I might slowly build the the center channel, RL, RR and subwoofer. If I go for a 3 way floor standing for my mains now, would it become waste (or redundant) when I buy my subwoofer may be a year from now? In that case would it make sense to go for a 2 way speaker. If I go with 2 way speaker, would I loose a lot in the bass because there are no low range dedicated drivers? How are Yamaha NS555 considered?
