I feel a need to reply just to close out my thoughts on my soundbar ventures....
I ended up trying the JVC BA1, Slimstage30, and the yamaha 400 as well. My wife thinks Im crazy and not sure why I care so much about this but finally made a decision
I literally watched the same scenes of movies and music sitting in the same exact spot and just changed the bar.
I bought the BA1 at frys with expectation that it would win out seeing everyone else's reviews. Not sure if it was my room setup or what but dialog really sounded muddy relative to the polk and slimstage. I tried turning center up and dialog feature on but never got it to sound as good. Also I could not detect any noticeable difference in surround effects from other bars. So I returned it.
I returned it for a yamaha s400 (the one with the sub in the receiver). Absolutely perfect bass. Really felt natural with the movie scenes and not that loose thumping and moaning you get from some cheap subs. Surround sound was next to none. Dialog was good but still not as good as polk or slimstage. Not really a volume thing, but more of a clarity thing. The voices where just not as crisp.
Now the polk 6000 and slimstage.... Both were spot on with dialog. The polk was a little better if I closed my eyes and really focused and switched between the two quickly. I used my def tech sub from my main basement system with the slimstage so bass was obviously going to be outstanding (which it was). The big drivers on the bottom on the slimstage probably helped a lot with the transition. The polk 6000 bass was also really good though. More than enough for my family room and the bass was tight and always felt right at home with the movie or music. I actually wanted to stay with the slimstage cause it looks awesome, has more control, does DTS, and gave me an excuse to buy a new sub for my main system
but in the end the polk 6000 won out. I dont know what it is, but really works well in my setup. I hate not being able to adjust anything on it, but really I have put it though multiple type of dvds, blurrays, torrents, cds, mp3s, etc etc looking for flaws and it has been spot on every time. I tried adjusting the slimstage settings for almost 2 hours trying to get it to be as clear as the polk, but never could. Now I am not an audiophile (which is why I wonder I have spent so much time doing this....) but just couldnt find that perfect setting that the polk seemed to hit out of the box.
I appreciate all the reviews on here and really enjoy reading them. Take this review as you want being I am not an expert like some of the guys on here, but just a honest guys review from my family room.
