Wireless JBL/Harmon Kardon setup question

[st4evr]

Hello,

I'm currently looking into buying a "JBL CONTROL 2.4G Control® 2.4g Wireless Speaker System" http://www.harmanaudio.com/search_br...202.4G&status= speaker set up with a small "JBL Balboa 100-Watt Subwoofer - 10" http://www.amazon.com/JBL-Balboa-100.../dp/B000O8WE66. The thing is i want to hook this up via analogs (RCA cables) to my PC, meaning, the wireless transmitter to the PC which transmits to the speakers and the speakers have sub out so I'll hook them to the sub for the bass. Anyone have experience with this type of set up? any input is greatly appreciate. this will only be for listening to music, as i wanna place the speakers and sub in the living room and do not want to deal with super long cables. The PC is in my room as i do not have room for it in the living room. it's an apartment with limited space so yeah. I was also thinking of getting a small receiver like the "HK 3390"
http://www.harmanaudio.com/search_br...203390&status=, which I'll hook the PC via analogs (RCA cables)to that receiver and then the receiver to the wireless transmitter for the speakers. But would that be necessary? Or just the speakers and sub be good enough to get a good loud clear music? BTW, it all has to be JBL, Harman Kardon, or Infinity brands as i have a family member that works for HK and they get 60 to 80 % discount. It's pretty much a deal i can't pass. Thanks to who reply in advance.
