I'm looking to get some new speakers and noticed that good guys is having a 50% discount on all the energy c-series speakers. the one speaker that caught my eye was the c-5. it sells for $378/pair (my budget is under $400) and looks to be the most capable of the bunch. how does this speaker perform and can i use it without a subwoofer wo any major loss in fidelity? I will be using it mainly for music.
