So here is a little info on my system before going into discussion. I am only 17 fyi, so this is what i have built up so far.
Front: Some old "vivid" brand tower's, used to be my dads they have an 8 inch woofer, 4 inch midrange and a 2inch tweeter. Not terrible speakers but not very good, hugely lacking in midbass.
Center: Klipsch Synergy C2
Rears: A pair of old Wharfedale Diamond III's, also my dads. These need to be replaced asap as the right rear tweeter is broken after a fall
Subs: 3 Klipsch sub-12's. Why you ask? Firstly, Im a bit of a basshead and secondly i only paid $750 for ALL 3. Kijiji, Boxing day and bestbuy floor model thats how i got them so cheap.
Reciever: Harmon Kardon AVR 146.
Room: ******. Not sure on exact dimensions but its 12 feet wide and id say about 25+ feet long, with horrible insulation/soundproofing. Can't be changed.
Now, having 3 of these subs in this set up is pretty overkill, but it really helps eliminate the MANY dead spots in the room. But my real question is what level of speakers do I need to keep up properly with the subs? I really like the sound of Klipsch products, and they are quite common here in Edmonton so finding them used and cheap is quite easy. What should my upgrade path from here on out be? I was thinking getting some RS-52's for rears, then new fronts. Should I get a better reciever too, the power ratings on the 146 seem really low, and it wasn't very expensive. With some higher end speakers I would assume a better quality reciever should accompany them. Thanks for any tips and info you guys have.
Ps. If this belongs in speakers more than subwoofer, feel free to move it mods.
