Summary: Believe the magazine reviews. The Alpha B1's (mine driven by a Yamaha RX-497) provide sound for my home office. I had suffered with another inexpensive speaker for several years and found myself simply not listening. One of the main reasons people like PSB speakers is they don't get tired of them. Many other speakers have characteristics that catch your ear to begin with but become unpleasant over time.
Summary: These are excellent budget speakers. You will be surprised how solid and attractive they are. They have a nice soundstage, and a balanced tonality. The bass is not deep, but they are bookshelves, so no one would expect that. I can't imagine someone not being happy with these for the price. I also cannot imagine someone thinking there is a better speaker at this price point. Maybe for a hundred more, you could get a little improvement, but not at this price.
Summary: Great for medium sized spaces. Bass extension is surprising for a package so small. The midrange is superb. I traded in a large set of Polk Monitor 70's for these - which were huge floorstanders that were much more expensive. These PSB's put them to shame. Great musicality and articulation. I pair these up with a Cambridge Audio 540C CD player and Rotel 1062 Amp. The speakers are mounted on a set of 28" Bowers and Wilkins floor stands.
Summary: Reasonably priced and sounds good though I am not a audiophile but has a good ear for music. I have been buying all my electronics from Crutchfield for about 20 years as no one could beat their service and Eddie is my favorite sales advisor.
Pros: Good base for its size and clarity of music.
Summary: I have to say I've been surprised and impressed by the sound coming from the Alpha B1s, from the overall smoothness and balance to the surprising bass to the mids, which are the "special" strength of this model. I have owned significantly more expensive tower and bookshelf speaker speakers, and the Alphas do not compete on output or size (nor did I expect them to).
Pros: Mids, overall balance, well-rounded bass. Understated appearance. Very surprising performance from a bookshelf speaker of this price and size.
Cons: Not much, actually. Maybe it would be nice if Crutchfield carried some of the other finish choices.
Summary: I'm blown away by the musicality and sound space of the small, entry level speakers.
Pros: Simply fabulous in the mid-range, especially on vocals and instruments like the clarinet, violin, etc.. The sound space is great as well - "sounds like you're there". Big sound, especially in a small or medium sized room.
Cons: As you would expect from small bookshelf speakers, bass output will be lacking if you are listening to music that wants that. Add a subwoofer in that instance.
Summary: These speakers are incredibly clear. I love the big speaker sound from such a small bookshelf speaker. After listening to many different bookshelf speakers from many differnt manufacturers the PSB Alpha B1 had the best combination of clear, crisp highs and very impressive lows in an econmical package.
Pros: Space saving design. Well made enclosures. Awesome music/movie sound reproduction.
Cons: None so far. I've only used them in my home theater for a couple weeks.
Summary: I've only had these speakers for a few weeks now, but I think they are great so far. They are small, but do better on the low end than I would have guessed. I thought I might have needed a subwoofer, but right now, I am not planning on getting one. Another great things about these PSB's is that they are not picky as far as placement.
