The ZVOX combines the speakers section—actually three individual 2.5-inch ferrofluid drivers and an internal subwoofer ported in the rear of the unit. The amplifier is also included in the cabinet as is the pre-amp section which allows you to select between two inputs. On the front is a volume control and something called a PhaseCue control, which is for adjusting the soundstage and creating a virtual surround sound effect.
There are a ton of small speaker systems developed for iPod on the market now. The ZVOX will also work with an iPod, but it’s not restricted to iPod only. Unlike most of the iPod clan of speakers, this one isn’t made of plastic. It’s constructed of MDF (medium density fiberboard), which is better acoustically than plastic.
The Phase trick involves mixing both in-phase and out-of-phase signals, the result creating the illusion of listening to several larger speakers rather than just one small one.
With two audio inputs, you can basically hook anything up to it from an old-school portable CD player, to a satellite radio. It comes with two cables, one for hooking up a source through it’s headphone jack and another for a source that uses stereo jacks. The ZVOX’s auto sensor turns the speakers on when you turn the source on. In my case, I first hooked up my Archos MP3 player and listened to some MP3 tracks encoded anywhere from 128kbps to 320kbps. When I turned on the MP3 player, the ZVOX powered up immediately and started playing. The digital music sounded surprisingly powerful. yy
