Buying New TV Need A Soundbar Recommendation

No, and don’t be an ass. My current screen is a 50" 2008 Panasonic 1080P plasma, running onboard speakers. I am not a big video person, I do 2 channel audio. This is mostly for the wife and our nightly TV watching, we like Star Trek series and other sci-fi. Will watch movies, but usually not more than one or two a week if that.

It was an honest question because I want better sound than what is going to be available on this thin  TV. But will not put in a full blown HT sound system.

@grinnell  The point of the post is that this is not a high performance installation in terms of sound. The wife is NOT going to use a HT system and doesn't want a bunch of speakers in that room. So an AVR and 5.1 or 7.1 system is not going to happen. 

The objective is to find a soundbar that can provide an improved level of sound and still be reasonably priced. I won't be buying the Focal or B&W units, but will not be going cheap. So looking for candidates that fit the bang for the buck niche. 

Thanks for all the responses, I appreciate all of them and did not intend to be snippy. I was at work and posting between tasks, so the writing style gets very direct and blunt as I have short blocks of time available. 

The LG recommendation and the associated interfaces available due to being the same brand it tempting. The Sonus bars seem to get pretty positive response, but they are so small I wonder how they accomplish this. A small wireless sub makes sense and will be used. 

I appreciate all the posts, even if I won't be going the way of powered speakers. The soundbar is a big enough intrusion for the wife, as she wants minimal electronics in the family room. Could be because I have a large pair of JBL floorstanders, Velodyne subs, monoblock amplifiers and two turntables in the living room. So I am trying to follow her wishes the best I can and still get the best sound possible given these restraints. 

After work I decided to call over to Video Only and see what they sell a 65" LG G1 OLED for. They were having a close out for the upcoming model so I got So I got one for $1699 rather than the $2399 at other places. That works for me. They bundles a Sound bar from Samsung, the HW-Q900A for $599 versus the $1097 I saw at other sites. Paid for it and will pick it up tomorrow. Should be a good purchase for the price kind of buy. 

Thanks all, I will be picking up my order Saturday. I needed to grab the TV quickly as there was only one of the G1 in the box left, as the G2 is now coming out. Works well for me as its a significant discount off of normal selling price. Of course it could have been a crafty salesman technique and there are 6 more in the back room, but I knew I wanted a G1 and the price is good so I could not take the chance there was only one. Have that happen before and seen it sold. 

When I get to the store I am going to see what they have for the Sonus soundbars and see if I can give them a listen. I am not adverse to upgrading to the Arc ones if I can hear them being worth it. 

We kept our Panasonic plasma for a long time, but we are not heavy TV users. Bought it in 2008 and the best deal available then was at Costco for about $1200 for a 50 inch. Picture is still good on it and functions as it should, Panasonic built a heck of a piece. This TV is probably overkill for us but I would rather buy up and for  the future as we do not change things out quickly but wait till things are used up. 

With any luck I will get to hear the other sound bars, the Sonus seems to be well thought of also. But if not then this LG should be just fine considering I spent the last 14 years hearing the speakers built into the Panasonic.
