white wolf

i cant believe KLIPSCH is so good. i cant believe what i am hearing . the sound quality is too good. now i see what KLIPSCH stands for. its working cool and i have had no problems. here is my question: when i shut down my pc then should i switch the bass subwoofer power button which is on the back or should i leave it on all the time ( just close the power from the sattellite speaker). My brother has another set and he has not switched the power from the back since 4 months . what should i do . Is is meant to be now swictched off?

i was thing about buying the 4.1 for 300$. well they are DAMN expensive. i neeed to know that should i go for them . what i am worried about is that if i buy these (since they are a bit old) then what if KLIPSCH comes up with the new set of 4.1 then what. i just need a confirmation from you guys or a KLIPCH official that there are no new 4.1 in the works and i can go for these 4.1 help needed please reply.
