I want to build a set of tower speaker for my Home Theater system and need a little help picking drivers. I have around 3-400 to work with and am looking for a high output SQ set-up. I have a 7.1 AV Reciever with 125 rms per channel to power them. I was thinking maybe a supertweeter or horn in each paired with some midbass/midrange drivers. I have searched parts express and madi sound, but I'm not sure exactly what I'm looking for or what would work well. Any suggestions?
