A "single, two-way surround speaker"?
Single speaker and "surround sound" are mutually exclusive terms.
"Audio lens technology" apparantly means that the "woofer" fires at the floor, the tweeter fires upward and the sound is directed 360 degrees by a curved reflector.
That means there will be absolutely no stereo imaging - the thing is designed to scatter the sound around indiscriminantly - hence "surround" in marketing-speak I guess.
"no AC cord" - no, instead it has an audio cord and a USB cord for power. 2 cords = 2 cords...
The woofer must be all of 2 inches in diameter. Bass response in any speaker depends on the size of the driver (the speaker) x the effective size of the enclosure x the power delivered to the driver x the efficiency of the driver.
What will it sound like? Well, it will be weak, because it can draw a maximum of 500 mA current from the USB, it will mono with no stereo image at all, it will have little or no bass compared with a subwoofer (small driver, low power, tiny cabinet size), but it will have a clever orange power light.
