great sound with a wide but not surround (rear) soundfield


  • from Kirkland, QC

Polk soundbar Audio MagniFi One

Great sounding device I appreciate having 3 inputs that can be selected from the unit or remote control being Bluetooth , optical and 1/ 8 " headphone signal (aux) I hooked up the Bell TV box optical output and it sounds better than the aux input when connected to the TV headphone jack . Essentially you could hook up a radio or CD player with headphone output to this aux input . The signal and input that I used the most is blue tooth connection from a tablet or netbook to play mp3 files and it sounds good to me. The remote bass woofer with its down firing bass driver can rock the floor but the sound is well balanced especially for listening music. This sound does not compare to my previously owned JBL speakers that were the size of a small fridge but it sounds better than my Bose Series II SoundDock especially when you want to fill an entire living room with music

  • from Alexandria, ON

Great sound for the money!

Since this is the only sound bar I ever owned I can't compare to others but it's exactly what I needed, it sound great and the price was right.

  • from Prince Albert, SK

MagniFi One 240W

Honestly this is my first time using a Sound Bar. Coming from a guy who had a 7.2 Home Theatre and many other I can say this is truly a great investment. I am super stunned on the performance of the Sound Bar. To be able to adjust the sound from your couch is a Plus as well. The Sub quite a bit of Kick as well. Compared to 2 10" Polk Subs I am astounded. You want great sound. You got to get POLK AUDIO

  • from Toronto, ON

Pretty good sound system

Met all my expectations in terms of sound quality and overall performance. Would have given it 5 stars, if I didn't have to return my original unit as the sub didn't sync with the bar. Would recommend it given the features and overall value.

  • from Belleville, ON

it's ok

sub is down warded firing too boomy for a small room no independent gain/volume. Bass adjustment on the sound bar is insufficient to resolve this issue. Sound bar adjustments return to default every time it is turn off and that is annoying. For the sale price of 199 it is ok

  • from Dundas, ON

Good product

I have always found Polk speakers good value. They are attractive and offer good sound. I had to downsize and replace my 5.1 Polk Theatre system so I went for this Magnify soundbar. The ease of setup was impressive and the sound very good for such a small system. The sound bar sits easily in front of the TV without blocking anything and the subwoofer connection works great. So far no complaints.

  • from Port Coquitlam

Awesome sounds!

I just bought it, this is my first sound bar i like it the crisp and bass is cool, planning to buy again soon i love it #polk

  • from Airdrie, AB

Great sound for the money

Awesome sound, coming from a very picky audiophile. Bought to replace a Sony soundbar & sub that I was not impressed with. Setup was easy, I had it playing music within 5 minutes of walking in the door with it. The sound is very crisp & clear and bass is amazingly deep and punchy for a wireless sub. Other bars I demo'd in the store with massive subwoofers didn't have nearly the fidelity that this one has. Great buy!! Highly recommended.

  • from Sudbury ont

Awesome sound

Great product for the price very crisp and good bass

  • from St. John's, NL

It's good, for the price.

For the price bracket it's a good sounding speaker. Bass is good voices are good and movies and shows sound great. Music might be a little lacking and features are few on this model. For a budget I would buy it again.

  • from Ottawa, ON

Great Sound Bar

I hadn't heard about Polk before but after purchasing it and trying it, I love it. My tv is in the basement and when the furnace goes off the tv speakers just weren't cutting it, Ever since I started using the polk soundbar, the sound is so crisp and the wireless subwoofer gives it that extra kick.

My Older Brothers Eyebrows Raised!

Bought this for my 17th Century brother who wanted the 22nd Century feel but was crippled with tech. I threw this on the sales counter along with a Samsung LED TV and Harmony Remote. In an hour the moment of truth came and lol his eyebrow jiggled wildly.. I'll admit the sound that came out of the bar was very full... I'm a hifi fan and will say that for the ease, cost and looks this is a great performer.

  • from Halifax, NS

Going to sleep mode frequently

I recently purchased this product from Halifax with great expectation. Sound quality is good but this device is going to sleep mode frequently. Some times it is working perfectly.

  • from Vancouver, BC


Easy set up but subwoofer was making popping sound. Returned subwoofer and new one makes same popping noise. Not sure what the problem is. A bit frustrated.

  • from Grand Forks BC

Polk Audio Magnifi One 250 w

Excellent value, hooks up easily and great sound for small/midsized room

  • from Montreal, QC

Got this bar to replace a Samsung that just stop working

I choose this one based on review + on their web site.... fortunately this is not expensive... I got one, Bluetooth was not really working, got it replaced... it work better, but very painful... sometime Bluetooth doesn't work... now optical doesn't... very painful it's a write-off for me... never again... BestBuy should not sell this brand it's crappy I will get a new Samsung always work perfect until it die...

  • from Ucluelet, BC

Awesome truly amazing difference for only $250!!

We bought 3 of these for us, mother in law and my parents. The voice accentuation , bass and volume control to pull out dialogue was an astounding diffeeenxe Highly recommend

  • from Etobicoke, ON

Polk Sound Bar

Great Price, Great Sound. Gave it four Stars because there are no HDMI plugin.

  • from Markham, On

Great sound bar, but issues with wireless sub

Bought this in Jan 2017. The sound is great out of the box, better than Samsung TV speaker for sure. My reason for giving it a 3 start is with the wireless sub, it keeps loosing connection with main speaker when volume is high. I've tried blasting youtube songs and i can hear sub lossing connection/pops (the popping noise relates to loose signal). I thought it was defective and exchanged for a new one only to realize the problem is with signal. I manually sync'd the sub and still having issue. The sub is barely 3 feet from the mounted speaker, so no, it's not the distance. Having said the above, it does makes everything sound great, and for general use at low-med volume you'll enjoy it. Love the night feature to reduce all low ranges so we don't wake up the kids. Mixed feelings. :(

  • from Mississauga, ON

worst decision

I bought this just over one year ago. Initially i was surprised by the sound but after exactly one year, I started noticing a crackling noise from the subwoofer. I am hunting down my receipt to send this garbage back. I also googled crackling noise from Polk MagniFi and apparently LOTS of people have the same problem. DO NOT BUY THIS.

  • from Scotsburn nova scotia

Polk sound bar

Great system for the money you won't be disappointed

  • from Richmond, BC

excellent & reasonable price

Excellent adjustable sound range. Voice is much clearer than my previous soundbar and surround systems(no more guessing what was said) Controls match up with cable remote easily. Sub is substantial even at 3/4, and have never needed full volume, on variety of sources. All around good purchase.

  • from Halifax

Sound quality is good unit but has issues

2 days before i purchased this device from Best Buy , Bayers Road, Halifax .The unit would randomly go to sleep. I researched online and found out this was a common problem for this unit. I am planning to return this product.

  • from Edmonton

Polk Magnifi one

Puchased it a week ago, very impressive sound and deep crisp bass.. I recommend this as well for karaoke or videoke sound. Love it.

  • from Whitby, ON

bluetooth issues

Purchased this on sale based on so many good reviews. The sound bar sounds great when working properly very clear with room filling base only issue was that the sound bar and subwoofer kept losing sync which became very annoying especially when I returned it for an exchange only to have it happen to the second unit as well. It seems that if you have a lot of wifi traffic in your house it could interfere with the Bluetooth connection between the sound bar and subwoofer.I have bell fibe tv so its all internet based and the router has to be close to the tv.. Wish it could have the option of being wired as well.

  • from Sault Ste Marie Ontario

My older brother grinned instantly!

Bought this and a 43 inch tv for my brother who is totally Tech inebriated. He shuddered at the thought of it but commented that it looked 50's classic. When it fired up he immediately looked at me and had that 15 year old grin that said "turn it up". He is 67..plain and simple and he's never giving this up!

  • from Vancouver, BC

Polk system

Thought it was well worth the cost Great vocal playback and easy setup

  • from Swift current

Polk audio

Love it...great sound...great price!

  • from Surrey BC

Amazing sound

Purchased this few month ago with my samsung TV and loving it. Without movies sound dull and boring. Just add this and u will feel like living the movie. I love how easy we can set it up and how easy to switch from movie to music. Base is pretty impressing as well

  • from Coquitlam, BC

Fantastic Sound

Was deliberating going for a higher priced, more powerful option, but I'm so glad that I went with the 250W MagniFi One. Have never even gone near running it at maximum volume as I haven't needed to. Powerful sound, with great bass from the wireless subwoofer (which looks really sleek!)

  • from Surrey, BC

Really impressed with the quality

I m very impressed and happy for my purchase...I m loving it..

  • from Belleville

Not impressed

First night with it, was sounding awesome until second movie speaker blew at 3/4 volume Gonna be taking it back and going with something a bit more premium.

  • from Burlington, ON

great sound

Bought this bar the other day. Took me about 5 minutes to hook it up! Super easy install! Ran my music through the Bluetooth option and it sounds really good. I was very impressed with the clarity. The tv sounds great! I had an older surround sound system and this blows it away!! I am very pleased with the purchase

  • from Vancouver, BC

The only soundbar with the real boom boom!

After literally 6 months of looking for the right sound bar that could produce some deep bass with crystal clear highs for the sports, action movies and hip hop tracks with deep bass...this beauty delivered. It was easy to set up and has a great clean slimline look. Once set up I took the system for test drive and WOW..the bass was shaking the glasses in my condo. Great unit and for great price.

  • from Brampton, ON

good buy

Sound quality is great. Good buy for the price point. No complaints

  • from Calgary, AB

Amazing sound

First sound bar I have ever tried and it is amazing. I'm still surprised by the sound out of this thing.



I got this on sale so I was even more pleased. Polk yet again comes through with the goods. The sound quality is exceptional, well designed, easy to use and easy to connect TO TV. Really nice shape and as it is not very high all of 2" it fits in front of my TV with ease. The depth is only 3" and the length 34.72". It has adjustments for voice which is great, music and movies. Overall I am one happy customer

  • from Milton, ON

Not what I expected!

I was expecting a high quality, full sound system, but this unit did not live up to my expectations. Sub did produce the low frequencies I thought it would, and the high end frequencies were lacking as well. Price was ok for this unit, but if you are expecting great sound, go with a better model or proper home theater system.

  • from Halifax, NS


Just picked up this unit for a 13 x 10 foot TV room. I mounted it below my TV given this is ear level when sitting on my couch. Full install was 10 to 15 minutes even after putting the plugs in the drywall to hold the sound bar; put the sub woofer in the corner. Sound is rich, clear, and on reflection I can't believe I went all this time without a sound bar. Lots of volume, lots of beat. The sound quality is exceptional at this price point . My 13 year old came up when it was installed and his comment was priceless - where has this thing been all my life? Very good product and recommended purchase.

  • from Loreburn, SK

Great price for good quality

At first I was a bit troubled that there are no controls for treble. I am used to at least three bands. This essentially has two, with the mid range (geared to voice control) being a bit different than typical. Also, I first thought it a bit annoying to have to switch from music to movie when much of my entertainment is a mix up and I would rather have one setting that is custom to accommodate either. Then we sat down and listened to a number of rock, symphony and metal music videos-- really gave the system a good working over! My first impressions were dismissed. This is an impressive budget priced system. I was able to push it to the top end of output and get clear/clean, no flutter, good rage of sound. We certainly had no issue filling our 130sq' living room (and 750'ft home) with booming sound! Running one's audio through a multi-band equalizer may help give some control for those that desire it; I will try this for my own personal customization, but out of the box, this is a good system for most music genres. I have not tested it out properly for movies, but I am sure it will be as desired. Set up is very simple and I appreciate all the cables for connectivity options being included. Wireless bass opens up for more placement options. The ability for the device to be programed with other remotes is a great feature.

  • from Port Coquitlam, BC

Very satisfied

High quality, beautiful sound, well designed, easy to use and easy to connect with TV and cell phones.

  • from Waterloo, ON

Awesome Soundbar

Picked this up on Black Friday. Works great, sounds great, Polk delivers another great product. I use this on my main floor listening to my IPOD, watching TV and movies etc, and I couldn't be happier. Simple set up, wireless sub works great, packs a punch.
