I recently listened to the pioneer sound bar and speakers. They were set up in a room at a dealer and the speakers were paired with a Pioneer Elite receiver, I forget the model number but I'm sure it was more expensive than the speakers. I didn't listen too critically as I already bought my system but I wanted to see what all the fuss about Andrew Jones is and spent about an hour there. I will say before I give my opinion is that both the speakers and sound bar are an outstanding value.
The sound bar suffered from the same things all sound bars suffer from and that is a very narrow soundstage and little separation. Off to the side it was not very good either, so if seating is to the side it might not be a good choice. It did have a good sound and while I have heard better sound bars none within a few hundred dollars of this one. This sound bar easily beats the Sony, LG, Samsung, Panasonic, Yamaha, Vizio and JVC sound bars I heard remotely close to this price range.
The speakers are even a better value, the books shelves lack that punch and fullness but do very well for a 4" midrange. Better than the sound bar for off axis seating and was surprising very good for this price range. The towers do great too but still need a sub.
If comparing the bookshelves to the ones I mentioned I would take the Mackie, JBL or M-Audio over the Pioneer. The smaller ones I would have to listen to again to compare. The Pioneers are not the best speakers I have heard. But let's be fair for less than $100 a pair street price they are very good, even when you factor the cost of a small amp. If someone is looking for passive speakers I wouldn't hesitate to pick these up and add a good sub.
Neither of these products defy physics but they are well designed for their intended use. Small speakers lack punch/ fullness and sound bars can't overcome that separation/ soundstage. While these products might not be the best, they are an unmatched value in their respective categories and I understand why people rave about them.
