Home loudspeakers are evaluated on a cost vs performance ratio, and these speakers, in their price category stand alone for performance characteristics. On balance they are equal to, or exceed sets costing twice as much. The main reason being is their bass performance. These are a little small for floorstanders, and too large for bookshelves, but that's the key to their success. No bookshelfs in their price range can get as low as these can because of their size, and no floorstanders can match them in that price range for refinement. The only drawback that I saw in them was their relatively low sensitivity, and somewhat recessed mid range. A quality mid level amp should be considered necessary for party level SPL's, but for a small to mid size room, 80 watts per channel should be sufficient for most users. I compared them to my Def Tech SM450's which retail for 3x the price of these, but can be had street price for 2x more, and they fared well. The Pioneers had a slightly better lower bass, and somewhat more refined character. I connected them to a PSB sub zeroi, and they blended seamlessly with the sub set at 75hz. These speakers can perform satisfactorily without a sub, but when one is added, the sound reproduction can approximate speakers costing way more. I wish I had known about them before I got the 450's as I could have saved $125 bucks, and have been just as happy. Those in the market for new speakers that can be used as bookshelves in the right environment, or as floorstanders using small speaker stands, must audition these before digging too deep for quality sound, and kicking yourself later on after hearing your friends set.

EDIT 1-25-2013: I finally received placement speakers, which are the newer model of these. I am completely satisfied with Pioneer support, but the process took a while, partially due to my fault. It was hard to find a box and pack the speakers. I recommend you keep the box. In the new version, each tower speaker comes in separate box.

EDIT 11-21-2012: A few weeks ago the tweeters suddenly "blew" (burn smell) in 3-4 towers during normal listening and I am working with Pioneer warranty. The bookshelves and center was fine. This is unacceptable and I believe the towers have a design flaw that caused this. I am using a Denon 2112ci AV receiver.

EDIT 10-9-2012: A new model of these speakers have been released. I am not sure if they are better or worse (supposedly better). The price of these will likely get to clearance status soon.

I bought these speakers including the matching center channel and 2 bookshelf/surround for my system about 4 months ago. BestBuy had a deal where the whole package was $280 (no joke) and I jumped on it.

Short version: These speakers are the best choice for someone on a budget.

I spent a lot of agonizing research to find the best speakers...which is hard because you can't really test them before purchase. Thus, I do not know exactly how every speaker sound systems and can only judge what others have recommended in reviews and my expedience with these.

Highlights/comments about these speakers:

They require the power output most AV receivers supply, meaning you are probably aren't going to over or under power them. A lot of more expensive speakers require separate amps and will not sound good with only a AV receiver. Fortunately, these are simply plug and play.

I got my speakers from the local Best Buy store rather than Amazon simply because I didn't want to wait for them to ship. Best buy sells them for $205 which is only six dollars more than Amazon without having to wait for them to ship. I have had these speakers for about six months and I am very impressed with their sound, especially for only $205. The description above from Pioneer does however need some correcting and is a little miss leading. It says above in the review that "Using three woofers with oversized magnets for powerful bass". These speakers do NOT have powerful bass! They do however produce an adequate amount of clean, clear, and what I would call a shy sound of bass. What I mean by that is they do produce bass but not very much, but the small bit of bass that does come out of these things is very clean and crisp. Just don't expect your walls to rattle or to feel "POWERFUL BASS" because there's not any. I'm not downing these speakers by any means. I highly recommend them, just thought that the future buyers should know this small misleading fact.
Before I tell you how great and wonderful these thing are and why you should buy these speakers, there is one other thing you should know if you are considering these speakers. They have this overwhelming tweeter problem. The tweeters on these are very loud and can sound quit muffled and have a horrible echoing sound. I have solved this problem by simple turning town the tweeter output on my receiver. This has solved my issue concerning the tweeters. Some might say the problem was probably with my receiver and not the Pioneers, but my father has these same speakers on a Sony receiver that does not have the function to turn down the tweeter volume like my Pioneer VSX-1021 does and Guess what? They have this tweeter problem.
