The Alto 3 is the smaller, cheaper option and is intended for smaller areas like dorms. It doesn’t have a built-in or externally supplied subwoofer, so what you can expect is stereo audio that at least surpasses what speakers on small, cheap TVs can provide, as well as Dolby processing, but not over HDMI, as it doesn’t. they have none of these jacks for input or output. The Alto 3 goes on sale in October for $ 59.
