THE QUICK TAKE: If you like the design, and need a 2.0 desktop speaker system, these are a good option at current (2011) prices.
FULL REVIEW:
Altec Lansing has been making self-powered speaker systems (the amplifier is built in) for as long as anyone, and they are very good at it. The speakers work well for their intended use, with effective and efficient amplifiers and drivers, and are built with solid quality.
These speakers are pretty much exactly what you should expect. For what it is, it's a good system, but will likely appeal to those who want a two speaker desktop system with limited bass and an industrial style.
So what you see is what you get. With one big exception - the [original, now removed] Amazon pictures seem to show a clear front panel. It's really a dark transparent gray / black. See the Altec Lansing website for lots of better images. I like the dark color more than I would clear, though. The speakers actually look better in person - for example, the silver ring around the speaker has a nice knurled detail that adds to the industrial look.
Also, the actual dimensions of the front plate are about 6-3/8" high by 5-3/8" wide. (Though since it's angled back, the height of a speaker is really about 6".) It's even wrong on the Altec Lansing site. The front plate seems bigger than it needs to be (though in theory it's possible there are acoustic reasons for the size, it may serve as a "baffle"). In any case, they are probably bigger than you'll think, so get out a ruler and try to imagine the size.
DESIGN: This design does offer the market a new option, and not just in how they look: most speakers are taller than they are deep, while these are deeper (6.5") and not so tall. So if that works for your setup, these are one of the only options. Otherwise, the design speaks for itself - either you'll like the industrial chic look, with the prominent Altec logo, or you won't. A buyer can easily decide that for themselves, so there's not much point in reviewing how they look.
LIMITED BASS: It should also be pretty clear what this isn't - a system with real bass. These are small speaker drivers (3") in small enclosures (6" deep by 4" diameter), and there's no bass speaker. That kind of driver and cabinet combination just won't produce bass. So this system is suitable mostly for those who don't want the "subwoofer" underfoot beneath their desk, or who can't have that in their setup (due to co-workers or sleeping children nearby). There's no point in reviewing this as if it should have had more bass, as some do - it's a 2.0 system, with small drivers and cabinets. The lack of bass shouldn't surprise anyone.
By the way, as with almost all such speaker systems, the specifications (other than the dimensions!) are mostly meaningless. They are measured at such a wide sound range and high distortion level that they aren't helpful. The frequency range they give of 100hz-20khz is over a rather meaningless wide range of sound level. Similarly, they 7.5 watts per channel is only delivered at an unacceptably high distortion level, 10%. (Though they deserve credit for including that more complete information, as many makers do not include complete enough specs to mean anything.) So evaluate these with your ears, not your eyes. That said, for a 2.0 speaker system that you'll be listening to at close range, they are powerful enough and sound good. If you want a system that you'll listen to from across the room, you may want to consider something else.
It's good that they have an auxiliary input for other audio sources. Though personally I'd find an earphone jack useful, it's a shame there isn't one.
It's also a shame that the two speakers are hard-wired to each other, it's easy to imagine someone needing to snake the cable through a shelf or desk area.
So, if you like the design and the price, and need a 2.0 desktop speaker system, these are a good option at the current discounts from list price.
UPDATE (2010-03): There's not a lot I'd add to the review, my early impressions haven't changed, with one small update: I haven't found the location of the On / Off switch and volume controls to be a problem in my setup (on the desk), but some might. I do, however, really appreciate having a separate on/off switch and volume control - I don't have to re-set the volume every time I turn it on or off. People who never turn them off might not appreciate it, but others will.
Sound quality is detailed but a bit hollow sounding. Not surprising for speakers of this type, maybe it's the very lightweight enclosures.
