Yamaha Air Surround YAS-70

The good: Virtual surround "1.1" system includes a single 4-inch-high soundbar speaker and full-size subwoofer; eliminates the need for other speakers; built-in FM radio.

The bad: Undernourished dynamic oomph; no video-switching capabilities; only supports three inputs plus iPod dock; no auto setup or calibration; wireless subwoofer would've been nice; best suited to modestly sized, clutter-free, squarish rooms.

The bottom line: The Yamaha YAS-70's included subwoofer and affordable price tag make it a tempting choice for virtual surround fans, but it lacks the impressive sonics of its pricier Digital Sound Projector siblings.

Description: The Yamaha Air Surround YAS-70 is a single speaker, virtual surround surround sound system. Compared to other virtual surround speaker systems on the market, it is midpriced at around $440.

Pros: Has an active amplification type, which is considerably more favorable than some similarly priced speaker systems. Selecting a speaker system (rather than mixing and matching components) takes the guesswork out of making sure you have voice-matched speakers. Matched speakers in a home theater speaker system will result in a more flawless, believable, and full sound experience.

Cons: None noted, given available product data.

Suitability: Suited for the smallest of rooms or for when you don't want the visual intrusion of multiple speakers.

Value: Overall, this speaker system's features are in line with its price.
