3 out of 5 eggsDecent Sound Bar

Pros: Looks good, matches LG LED TV's nicely - Good Form.
Stand is high enough to sit over LG TV base - Good Form
Adds robustness to the TV's sound field - Good Function
Digital Audio Inputs - Good Function

Cons: Not wall mountable
HDMI's are audio only
LG system link to TV does not stay programmed
Dimmer state does not stay programmed.
When system linked to TV, volume for TV and Soundbar are not controlled together (you can control one or the other).

Other Thoughts: I paired this with the LG 47LS4500 and the LG BP220.

As a sound bar it is designed to be in front of the TV. However, the display panel and control button lights are bright, to the point of distraction. A dimmer function is offered (but not documented - works by pressing the "sleep" button once on the remote) and does not stay programmed (power off the system and it forgets).

The sound is decent considering the small size of the drivers and no real sub-woofer (3" drivers, cannot be considered true sub-woofers). I would consider the sound sufficient for everyday viewing, but not in the class of home theater (not even entry level).

It does not function as seamless as I would like (sound volume should automatically goes up and down with the TV volume) and adds one more remote (despite the LG system link) to manage the details of sound bar.

It is a good sound. With a few engineering changes it could be a great bar. As usual, it seems like the engineers and designers don't use their own products and documentation.

However, it is overpriced at retail ($279). Get it on sale. I managed to find it for $179 (which I think is still just a bit too high for this class of device).

5 out of 5 eggsPretty Good

Pros: Good fidelity, sound fields selection, inputs. Good volume.
3 HDMI 1 HDMI out, Optical..USB
Remote is pretty good. Harmony Remote supported.
Front Panel display can be turned off.

Cons: Not really a con but,, the base for my TV was a few millimeters wider than the distance between the units molded feet. Hence the unit would not sit flush on my console top. This can be remedied with a little ingenuity, ;-)

Other Thoughts: None
