Recommendations for 1000


I need better audio for my home. I am using my computer to play music with a sound blaster X-fi card with Optical out and in and every other basic output. It is hooked up to a projector and is often used for dvds. I'm uncertain whether i should get 5.1 or stay two channel. I have a budget of 1k and need speakers and a receiver or amp. I am willing to buy receiver and 2 speakers now and add later if I must. I need some recommendation. I was leaning towards 2 floor stand klipsch and their 12 inch subwoofer. Thanks.

What would be a good place to just buy drivers? I would assume i could get some nice drivers and build the boxes in my free time. I am debating whether or not to do this but I do like the idea of building the boxes myself. I have read up on the "how to," and think its easily done right. Is this a bad idea or good idea, I think is what I'm really asking. Thanks PDN for pointing out the low wattage on that subwoofer, I would definately need to replace that with a bigger subwoofer.

Just the items themselves, I wouldn't buy from either of those sellers. But that would put me right at budget after receiver, but I can not find anywhere to hear these Quintet III because they seem to be above Best buy and Circuit City, yet below every high end place around(which really has me worried).
Cwaigy:

Try www.partsexpress.com. You'll be able to purchase a wide variety of drivers, enclosures, and crossovers here. As far as this being a good idea or not, I would go in to this knowing it's a risk and that the speakers may not turn out to be the sound you need or want but it would be an excellent learning experience. Would this be your first time or attempt to build loudspeakers? I think it would be fun and again a great learning curve. Glad I could help out a fellow audio hobbyist. Let us know how they turn out if you do make a pair. All the best.
Can you also point me in the direction of a good brand, the only one on there I know is amazing is JBL; sadly that would be out of my price range. I have built some dinky speakers before that I'm currently using to hold me over until I find some nice speakers. Thanks.
