Hi I have a question, I am researching on looking to buy a 5.1 system(no Sub) which includes center channel, front left and right tower speakers, surrounds and a reciever for around $2000 to $2300 price range, I have already decided on the SVS PB12-NSD Sub, which will cost a additional $700, so all i need is the speakers and reciever for around 2grand to compliment this Subwoofer,

I understand my budget is very tight, is it possible to get a decent set up with this budget?
I have been impressed by the sound of Bowers and wilkins, Paradigm, Salk, i understand these speakers are expensive, I dont mind buying used, and my favourite brands are Paradigm and B&W, and also i do want tower speakers , I do live in a apartment(planinng on moving to a bigger place or a house), my apartment is around 900square feet, and i live on the ground floor only attached to one niegbour, I would say that i would watch TV and movies 70%of the time , music15% and xbox 15%, as for music i listen to all kinds of songs.
Please help me find the right speakers, I do appreciate everyone reading this and taking the time to respond, you guys rock!!
