Surprisingly Great Sound & Bass
Small but mighty this soundbar and subwoofer pack a whole lot of sound and bass in a small package. I love how everything Bluetooths right to my TV, game system, phone and tablet so right out of the box it took under 5 minutes to have everything up and running. The sound from the soundbar is really clear when I'm watching movies and the bass doesn't drown out the dialog in the movie or tv show. I love how convenient it is to Bluetooth my phone to this soundbar and be able to listen to music with big sound instead of the small interior phone speakers.

Love the sound
I really like this Samsung HW-A450 Soundbar. We used to have a cheap soundbar with subwoofer and this one's sound is so much better. Both TV shows and music are so clear on this soundbar. It was very easy to connect to my TV but I do not have bluetooth, so I just used the included optical cable. It was very simple and also pairing the subwoofer with the sounderbar was a piece of cake. I really like the streamline design and that there are no visible buttons. The remote is easy to use and it is also easy to pair with my phone just so I can play music. This soundbar will be great for dinner parties or when I have friends over for movie night. I am very pleased with this product.

Great Soundbar
I consider myself to be a tech enthusiast and it is important that I have the latest technology which, in terms of sound systems, means it is important to me to have an immersive home theater experience. The Samsung Series A soundbars combine the trustworthiness of the Samsung brand with the technology to deliver amazing audio fidelity all at a reasonable price. The wireless subwoofer delivered a resounding bass while the Bass Boost feature gave an instant boost at the most opportune times. Setting up the soundbar was a breeze with the Bluetooth TV connection, which allows you to easily connect your soundbar to your TV wirelessly.

Makes Movie Night a 1,000x’s better
Exactly the kind of quality, build, and sound I expect out of Samsung. Out of the box, it is packaged well, easy to set up, has everything needed to have a fantastic family movie night. Be the hero your family needs with this sound bar with wireless sub. The included optical audio cable makes the connection from the TV a breeze to setup. It includes wall mount brackets, which we didn’t use since our tv sits on our dresser, so the sound bar sits in front of it. The wireless sub can sit by the dresser and provide wonderful sound that fills the room, or next to the bed and feel that home theatre feeling as it rumbles next to us. Same would be by our living room TV and couch setup if we preferred, except that TV optical audio currently doesn’t work, so we tested on our newer TV. The system also has built-in Bluetooth, easy to pair as well, and ready to party in a matter of minutes. Overall the system feels durable, easy to read the display lettering on the front white leds that illuminate the sound choices. The sound fills the room and makes movie night all worth watching, and semi drowns out the kids, they never stop talking though. Better than our built in TV audio, and the sound quality we’ve been looking for.

Really Really good
Wow! These were just what we were after.. We have a beautiful big tv but had a big problem because the sound was awful.. the music and bangs were way too loud and the speech was too soft. Then there were the adverts which seemed like they were on full blast..

This speaker set had been amazing! After 2 minutes plugging this in, the first thing we noticed was the bass . It's very very good but not over the top. The mid range sound is just sensational, it's pure quality! We no longer scramble to the remote everytime an advert comes on! It really has transformed our tv and movie watching experience and we are never going back to tv sound! We have also started steaming music through these via Bluetooth because they sound so nice!

i am having difficulties with set up. also -- i think you really really need to view the extended manual to set this up -- and i had to do a 20 minute chat to get a link to the manual. i can't get the tv or cable remote to control the volume. i finally did see in the manual that you have to click the volume button up or down to control the volume - but who would think to do that???? now i see that by clicking the woofer up and holding it up for 5 seconds should give me a choice -- that does not work. and by clicking the circle button to the left is another thing that should do something and that does not work. omg this is amazingly difficult.

Impressive sound, easy set up
I have never owned a soundbar but wanted a better TV experience. The set up was extremely smooth. I was concerned that the instructions were too short but it was so simple. I chose to set up my soundbar with the included wire versus Bluetooth. The set up took less than 2 minutes and the subwoofer connected automatically after I plugged it in. Everything was ready to go.

The sound is very clear and the system is user friendly. It comes with a.remote that is also simple and user friendly. My TV with the bar sounds so much better than my TV alone does. I'm looking forward to many future movie nights.

Nice soundbar
My household has never had a soundbar so it's great to start here. It looks great with our Samsung tv, very classy looking. Paired with Bluetooth it's made the sound so much better than just the tv. I never realized what we were missing. Instructions are a little lacking, feel these should be improved for the technologically lacking individuals. Looking forward to taking to our new home with the larger tv room, this will be awesome and can bring the sound throughout the room for a great experience! An odd comment, but the packaging is a little odd, but that's the items that are in it. Thanks for another great product Samsung.

Great Boom for the Buck!
The Samsung soundbar is fantastic. I haven't bought a soundbar in a few years because the ones I've had before less than desirable. The Samsung A450 is fantastic! The setup is quite simple. It's a decent size, and it fits well beneath my 65-inch screen on my TV stand. I used the optical wire that came with it to connect it to the television (which others I have looked at did not come with), so I utilized the Bluetooth for my children’s music stations on Pandora. The subwoofer is excellent phenomenal bass and boom for movies, and the sound is fantastic. I've got it hooked up to my TV and I'm enjoying viewing all of my streaming content on it. It's almost as if you're in a movie theater. I haven't even changed the settings because it sounds great in the default settings out of the box.

This Changed My World!
You never know what you are missing when you don't have it! I have had an amazing Samsung TV since last year and since it is so amazing, I wanted the full theater experience. Boy have I found that with this awesome soundbar!

Set up was so easy that my boyfriend and I did it in no time. Bluetooth capabilities make connecting the soundbar to the subwoofer and the tv easy peasy!

The surround sound is clear and just simply wonderful. Even the boyfriend who is hard of hearing keeps bragging about how he can understand every word during TV shows.

And playing music thru this soundbar is amazing. I felt like I was at a live show!
This soundbar truly is changing our listening lives!
