Very good over all with room for simple improvements. For the price, they are excellent.
I compared these speakers to a pair of Diamond 6's with a Rotel 40w amp. And also a moderate sounding 2.1 system.
Sound wise, I find the mid/high tones to be great, but the bass is muddy and poorly defined when compared to a hifi setup. Keep in mind though that I would not expect any other speakers at this price to be any better. I would guess that the internal amp is struggling to drive the bass...
Don't get me wrong, the bass is decent. Its just that the mid range seems to shine brighter and the bass doesn't keep up. Ideally the speakers would have passive inputs so they could optionally be used as passive speakers. wouldn't cost much to manufacture like that.
There is one small annoyance with them. the power switch is on the back, so I have them plugged into a switched socket and turn them off/on as needed. When you turn them on, the will not produce sound until the volume is increased. so you need to have the remote handy or reach around to the back again. All settings (vol, bass, treble) reset when you turn the speakers off so you can't maintain a setup unless you leave them turned on.
