Good for movies

These speakers are designed for surround sound and that is where they work the best. When bought on sale you get a good deal. Watch when purchasing online, they get shipped Canada Post Expedited and in my case, they sat in the local mail depot for 5 days counting Saturday and Sunday(I have to live those two days so they count). I filed a complaint at 5pm, and at 6pm there was a knock on the door, it was my old regular carrier from a couple of years ago, he said he had seen the box for a couple of days just sitting there. He asked my current carrier why was he not taking the box, current carrier said it was too heavy. Just a warning that if BestBuy is going to continue shipping this single box using Canada Post it may get ignored by the carrier. With all that being said, the box was heavy. And the sub speaker uses a standard RCA cable that is readily available in just about any store that sells audio or computer hardware.

Happy to bought this over Bose

Bought it yesterday and paired it with Sony STRDH590(so lucky to get the last stock). It sound great with specially with music. would recommend this to anyone who's planning to buy real 5.1 speaker system

Polk speakers

Small, not super loud, but very powerful and clear for there size. The subwoofer does not come with a subwoofer cord And I think it should be made available because It took me a week to find one.

  • from Victoria, BC

great speakers

I have used these speakers in my home theatre for 4 years and have been very satisfied with the preference delivered. once they were set to my Denon receiver and balanced sound was amazing. glad that these Polk Audio RM6750 are set available for others to enjoy the full sound

  • from Gatineau, QC

Nice full sound

Got these speakers a month ago and very happy with them. They are small but a nice a lot of clear and crisp sound is coming out.

  • from Oakville, ON

Small but powerful

Good sound quality, only issue is subwoofer is not level. Product image is not accurate, 2 fronts and 2 satellites are identical.

  • from Toronto, ON

Polk audio speaker system

Very good sounding, full sounding sub as well

  • from Fort Smith NT

Polk Small room 5.1 theatre speakers

I bought these on sale at Best Buy online. Love these Polk audio speakers, they make my Yamaha receiver shine. I would suggest if you only have a small Tv/movie viewing area these are a great fit. In a larger room they can be too small.

  • from Wasaga Beach, ON

Always impressive

Bought this set for our basement surround system, after buying the single base driver for our upstairs surround replacing a failed unit. Was so impressed with the single unit that we bought the set of 5 for the basement, sound paired with a Yamaha 300w per channel amp is amazing! highly recommend them to all...

  • from Toronto, ON

best value for the price I got

I got it with a very good price when on sale. The sound quality is beyond my expectation consider the price I paid.

  • from Toronto, ON


Sleek design, high quality speakers, perfect size, mounted to my walls. Subwoofer is massive. Sound crystal clear with nice deep bass, just make sure your receiver settings are optimized for best sound. Very happy with this purchase and enjoying movies, sports and video games.

  • from Brighton Ont.

Great so far

We only got it hooked up this week. We had the Geek Squad to hook it up. He was great ...I would get them to do it again. We really havent checked out movies or the music yet but as far as tv and netflix it works great.

  • from Trois-rivières, QC

Best of the best

Perfect sound coupled with Sony strdh550. Very satisfied.

  • from Bowmanville, ON

Polk audio speakers

It's a great all around system. From movies to music they sound great with little to no distortion on higher volumes. I would recommend this system.

  • from Calgary, AB


Had two Polk audio towers, so thought I would try these!! Very crisp and clear sound. Easy to mount!!! Very pleased with the purchase!!!

  • from Edmonton

Good but got fried

I hooked up this system to my pioneer vsx1028 7.2 channel receiver. Worked well for a while, I was wondering what these small speakers can do so I turned the volume up and all 4 speakers got burned, I actually smelled it in the room and my receiver got turned off itself. When I turned it back on only centre speaker and woofer was working.

  • from India, ON

Wonderful sound quality

Excellent sounding quality; I never experienced this quality before.. Blindly you can go with the polk audio.

  • from Kitchener, ON

Great mid range surround sound speakers!

Paired these with a Pioneer VSX-530-K and at a great price have a very good sounding surround sound system!!! Definitely recommend these, you can always trust Polk!

  • from Hamilton, ON

Great sound and value!

You cannot go wrong with this system. Perfect for my basement home theatre. The system delivers great sound for the money and even though the ref price is good it helped I got them on Boxing Day. Best Buy delivered in a few days with no issues. Don't overpay if you don't need huge sound and I don't see any issue with this product.

  • from Kingston, ON

Excellent compact system

Got these at half regular price, and really pleased. Paired with a Sony STRDN1050 receiver, and the sound is great. Crisp and clear, and does well in my medium-sized room. Classical music is well-balanced and full, and the sub gives plenty of bass for heavier music and movies. I'd say you can't go wrong for a starter surround system. To be fair, I'm not a metal-head and I'm in a town house, so not playing really loud or looking to make the walls shake. I'd definitely recommend these though. I actually just bought a pair of Polk T600 towers to replace the front L and R (and use the original two to make a 7.1 system), and I'm thinking about returning them, because there really isn't a whole lot of difference in the sound.

  • from Pickering, ON

Great System for a Great Price

I had an old Pioneer receiver that needed to be replaced and while I was at it - I decided we should upgrade our speakers as well. I got a Pioneer 80-Watt 5.1 Channel AV Receiver & Polk Audio 5.1 Home Theatre Speaker System for an amazing price after boxing day. It is all hooked up and sounds great!

Surely One of the Best speakers out available

I am no Audiophile but one thing i have is ears which can differentiate different Rich and Soft Music...This season i tried different sound system.. 1) Bose Solo II and Cinemate 15-- SOLO is definitely not recommended . Please don't buy it both are heavily overpriced (yeah yeah i know its bose and it has blah blah and blah and blah ... but for those BLAH and BLAH which hardly come to your ears you are spending 4 times more money remember it...).. BOSE is best for their headphones and buy BOSE if you are trying to buy a pair of headphones its worth it!! 2) Bose Cinemate 130 or 120 -- Buy only if you have enough money and not sure how to waste it!! buying this nancy fancy bose "technology (thats whatever they call it)" is just a waste of money literally!! one sound bar costs 1.5k!! are you kiddin me!! ** Don't get me wrong here they sound really good but my point is their price point is not justified... 3) Bose Acoustimass 10 -- again literally overpriced for the quality.. 4) Polk Audio RM 6750 with Pioneer Receiver -- Its Awesome!! truly awesome... Go and grab them... The deep low notes from the sub just amazes me.. the center speaker is a monster it spits out some real crazy sound. The deal i got and the value for money about this speaker is unbeatable... POLK AUDIO is definitely a better brand than many out in the market. Buy them when they are back on deal.. Hope this review will help to choose if you are comparing true 5.1 VS sound bar 5.1 and if you still wish to buy sound bar don't waste money buying BOSE or SONOS they are really really overpriced compared to the sound they produce Just doesn't make sense....

Really great sound and quality

These speakers are paired with a Sony Home Theatre we bought at Best Buy. We have a 20x15 family room, wooden floors and the sound is crisp, rich and the subwoofer is better than the Sony one we had before. The speakers are solid and hopefully, will be easy to mount on the walls. Watched a few good movies so far and we're really happy with them.

  • from Hamilton, ON

Man cave for the kids

So far the speakers sound great....they are mated to a Denon AVR500BT receiver and deliver clear sound in all modes. I still need to tweek the sub to get the right rumble...it is a medium sized room with plaster walls and ceiling so the sound really cocoons you.

  • from Burnaby, BC

reasonably priced speaker system

I have been in the market for a reasonably priced 5.1 speaker system for my basement tv and game room for quite a while. I have tried sound bars too. But they are not good enough. Until this Polk audio came out on sale so I took the bait. It does not have the power of a Bose but it has very clear and crisp sound. Base is strong enough and reasonably priced at that. Very happy with my purchase

  • from Scarborough, ON

A great value

Snagged these up during the online sale last night (07/12/15) and I am amazed with the quality. I live in an apartment, so these are perfect for my needs. Crystal clear audio. Paired with the Onkyo SR313 receiver. Quality build and the sub is just enough power for me,

  • from Montréal, QC

Extremely competent set of speakers

I bought these for a secondary home theatre system and they do the job rather well. I paired them with the Marantz NR1403 and am overall very happy with the results. I don't LOVE listening to music through them as the mids are a little thin, but for film and gaming applications they are perfectly fine. I do find the sub to be pretty boomy and unnatural at times and I find myself adjusting the crossover pretty frequently from listening source to listening source. But at the end of the day and especially at this price-point these speakers are a great buy. Recommended.

  • from Edmonton, AB

first and best home theater system for its price

I bought it online. The sound quality is really amazing! Specially when it is paired with a great receiver, surround sound will shock you! The bass is just enough to provide the great experience.

  • from Richmond, ON

boxing day sale.awesome price

Bought these after doing some research for mid priced theater system. Matched these with a Sony 850 dn. Sound is awesome,

  • from Otttwa, ON

Polk Audio

These are good speakers for the beginner. I have checked Boss speakers but these speakers are excellent for sound and price.

  • from Calgary, AB

Doing the polka with Polk

These speakers are very comparable to my brother-in-law's Bose speakers on the high end frequencies but the base is where the Bose takes the cup. A little more floor shaking base would of been nice but they provide enough oomph according to my kids since say their uncle's system is bit too much

Polk Audio
