Reddit mentions of Infinity Primus PC351 Three-way dual 5-1/4-Inch 3-way Center-Channel loudspeaker(Black)

SVS PB2000 sub -$800

Marantz SR5009 $420

Infinity primus center $200

Infinity primus towers $300 for the pair

Infinity primus bookshelfs $190 for a pair add another pair for 7.1

add another big subwoofer later for more oompf. the primus series represents pretty good value and they will play quite impactfully

then figure in another grand for a projector and screen

With a budget of $400-$500 you can put together a very nice 2.0 system. I'd get this:

Receiver $240: http://www.accessories4less.com/make-a-store/item/marnr1403/marantz-nr1403-slimline-5.1-av-receiver/1.html

L/R speakers $300 (if you can stretch it:) http://smile.amazon.com/Infinity-Primus-Two-way-Floorstanding-Speaker/dp/B0044D178S/ref=sr_1_8?ie=UTF8&qid=1426537117&sr=8-8&keywords=infinity+primus

Or $172 if you can't: http://smile.amazon.com/Infinity-Primus-Two-way-Bookshelf-Satellite/dp/B0045NCB32/ref=sr_1_3?ie=UTF8&qid=1426537117&sr=8-3&keywords=infinity+primus

When the funds have replenished get the center channel $200: http://smile.amazon.com/Infinity-Primus-Three-way-Speaker-Center-Channel/dp/B0044D1788/ref=sr_1_2?ie=UTF8&qid=1426537117&sr=8-2&keywords=infinity+primus

Immediately with the receiver and L/R speakers you'll need speaker wire 16 gauge min.), if using a cable box and/or DVD/Blu-ray you'll need HDMI cables for each video source plus an HDMI cable for receiver to TV. When you get the sub you'll need a long RCA cable. If you opt for the small speakers for mains you'll need a pair of speaker stands.

The matching Infinity Primus towers and bookshelf speakers have be on sale over the last few months. Here is the matching center for the larger towers at the cheapest it's been in a long while.

I just picked one up.

Also on Amazon for the same price

You can get the same receiver you listed from Accessories4Less for $169. So that saves you $90

I would also take a look at the Dayton SUB-1200 or SUB-1500. Both are well reviewed, and several redditors have used them in budget systems lately, with very good results. Say you go with the 1500, that saves you $40.

Are tower speakers essential? If so, I'd personally recommend the Infinity Primus p363 for your L/R. Much higher rated than the BIC, with fewer build quality issues. There are reports of the BIC speakers being top heavy, poorly fitting vinyl veneer, and rattling grills. In addition, horn speakers tend to be a "love it or leave it" sound. Even at the higher price the p363's are at, is still a superior speaker, or you could wait to see if they go on sale again. There are two Infinity center channel speakers, one for $199.95 and one for $149.95. With the savings from the other components, you could get either one.

If bookshelf speakers are an option, that opens up a whole lot of speakers that are superior to the BIC, especially if you're crossing over to a sub. The Emp Tek r5bi at $225/pr new or $182/pr Scratch and Dent has a rabid following here, and very favorable reviews just about everywhere. The matching r5ci is also highly recommended. There are alternatives from Chane (currently backordered), Home Theater Direct, and plenty of other Internet Direct and Brick and Mortar options.

If you have to have horn speakers, but bookshelves are an option, I'd take a look at the Hsu Research HB-1 at $159 ea. Or Klipsch bookshelves.

Craigslist tends to be hit-or-miss depending on the area you're in. I'm in the Plains states (SE IA) and don't really see much on the used market. Someone closer or in major metro areas (Chicago, Seattle, LA, etc.) will have better luck. However, I'd stick to speakers unless you or a buddy knows electronics repair. You don't get any warranties buying used, so caveat emptor.

Last thing, I personally wouldn't buy Pyle products even if you held a gun to my head. I'd take a look at Dayton Audio, Monoprice, Home Theater Direct, or even Polk before I'd buy Pyle. The other option is to sink that money into the fronts for now, and buy the surrounds later. It's not like the holes are going to fill themselves in. The other thing to look at is Dolby Atmos. You could set up a 5.1.4 system using the in-ceiling positions, and use bookshelf speakers for the rear channel.

Now, this isn't a huge knock against BIC speakers. Many people have them and like them. I just think that there are better solutions out there, especially if you can use bookshelf speakers.

How's that compared to this one?

Yep, these will work well with the Yamaha. You'll want to get the matching center channel. The BIC F12 is the best budget sub that'll reinforce the Infinity's well.
