The SurroundBar or the SurroundBar 50?
I don't have either, but can mention a couple of things:
1. The SurroundBar 50 is one of Home Theater Magazines top pics, but they don't recommend the regular SurroundBar.
2. As with any soundbar, it's dependent upon your room. If you have one wall that's just sheetrock and another that has a curtained window, it might not work that well. It's designed to "bounce" sound off of existing wall. For the same reason, if the soundbar isn't centered on the wall (with equal distance between it and the adjoining walls), it might not work well either (sound from one side will arrive to your ears at a slightly different time than sound from the other side which will create and echo effect).
3. If you can center your TV, your room is fairly symmetrical and you don't have any accoustical issues, the SurroundBar 50 should work well for you.
4. The ZVOX 425 is also a top pick and it's a few hundred dollars cheaper than the 50.
