My complaint is that on my TV's, the dialog is normal and the background noise is insanely loud. Often to the pint we turn on closed captions to watch TV.

Would a soundbar help or do I need a dolby multichannel unit?

Is a sound bar needed? Not really, if you don't mind muffled, unclear audio.
The same argument can be made about engine power. Are 700 horses needed? No, but they sure make for a fun ride.
Get a sound bar, you'll be glad you did.

Reviews aren't your own ears. I grew up in the era of music being on AM radio. So no bass for me. Too many systems today over boost the bass and I don't like that. So some unknown's review of a sound system is useless for me.

I did buy a Samsung sound bar for my Samsung TV off Amazon, figuring it'd be most compatible. Reviews were good. Not impressed with it's sound and it occasionally freaks out and both the TV and soundbar play, causing a slight echo effect.

Thanks for all the input. We'll hold off getting a sound bar until we see how good the TV sound is.

I got in on the tail end of plasma... lol I bought a Bose sound bar and sub with it. It cost more than the TV and was worth it to my ears. It has some kind of active EQ and 3D sound that adjusts it to the room. You sit where you intend to view and put on a headset that has mics in it. It plays a bunch of different frequencies left right and center and when it's done you can point to places in the room where the sound seems to be coming from depending on what's happening on the screen. Something crashes on screen and you look to see what the cat knocked off the table. Lol.

As someone that started watching TV on a 19" black and white RCA portable, seeing the words "basic" and "65" TV" in the same sentence is a bit of chuckle... lol

50 odd years ago if I came home and found a 65" TV in the living room I would wonder how the Drive In Theater got there...

And remember how the local movie theater had one or two speakers either in the middle at the side or top of the screen and in mono or on the floor. Now some or most of those theater's sound systems feel like you're getting your clothes dry cleaned. I bought a sound bar system for every flat screen TV in the house and a go sound system with sub for the PC. Haven't found a phone, TV, PC or device that has a good speaker(s) that couldn't be improved or upgraded. Yes there are some TV with "good" speakers/sound but "compared to what"?,..... other TV speakers yes but not compared to a soundbar. with a sub.

I'm 35, hearing is decent, and I can tell you (much like many others in this post have mentioned) the quality of speakers in these TV's today is subpar at best. I bought some of the higher end Samsung TV's (not the Black Friday special or anything like that) in both 43 and 65 inch, and both TV's sound is again, subpar. Is a soundbar required? Absolutely not, but if you don't want to crank the built-in speakers up and blow them out trying to hear what you are watching, then yes, get a soundbar. Good luck!

I would buy the tv and try it. That's the only way to know if you'll want a sound bar or not. I have 2 large tvs 1 a new led and the other a top of the line plasma. Difference of night and day between the sound systems but of course the plasma with the good sound system was 5 times the cost of the led.

They put cheap sound systems in the new one's to lower price knowing most people will end up buying the soundbar too. It took a while but by messing with the sound control settings I was able to get cheap tv to be good enough not to need a soundbar but still nowhere close to the quality sound system in the expensive tv.

I bought a new Samsung. Figured I'd add the $200 Samsung sound bar. What a mistake. The TV was louder. Even at 100% it's med loud. My hearing is failing (my wife says) so I need louder

I'd pass. Maybe the $1000 sound bars are better but I'll never know.

I'd say definitely yes.

The problem is if you don't try it, you don't know what you're missing. But then again, maybe that's an argument to not get one.

Now that I have been using them for years, I can't go back to just using the built in TV speakers. Plus, no built in TV speakers will give you actual surround sound that you can get with a soundbar that has rear speakers. I have a samsung 65" and a Vizio soundbar with wireless subwoofer, and the subwoofer connects (with wires) to two rear surround speakers.
