Mother of all Speakers

I have tired many sound bars around 300 canadian, but went home buying these, as sound bars were lousy. Trust me, they are one of the best speakers I have ever tried. All of a sudden my room turned into a Movie theatre. At times, I wonder that am in a theatre. it delivers such an immense sound and it a great experience. A great product from Logitech. THX certification ain't some promotional trick. Hear them to believe it. Buy this, I can assure you that, they will not disappoint you, in fact they will surprise you.

  • from Victoria, BC

Excellent for the price

I just bought these today and I am very satisfied with the audio quality. Deep bass tones resonate from the 130W subwoofer and the twin satellite speakers produce crisp, clear sound as well. Setup was easy and it took only about 5 minutes. The package includes everything you need including a 3.5 mm cord to connect your device to the speakers. Of course it also includes cables which connect the speakers to the subwoofer (which must contain the amp I would imagine). My only complaint is that the left hand speaker cable is a bit short. It is only about five feet long and in my setup I needed it to be about six feet long. Overall I would say these are an excellent bang for the buck and I would highly recommend this product.

This speaker setup is worthy of a review

Firstly, I never do reviews but this little speaker setup really deserves it. I have a Bose Companion 5 system for my computer but I figured it was time for something new. Man this thing really bangs. Super loud, lots of bass, I would compare this little setup to a midrange-highend soundbar like holy dayum. You will find that you might actually have to turn things down for once. The sub is really powerful for the price. 10/10 product Logitech. Beyond impressed.

  • from Woodbridge, ON

Better than I expected

I'm a bass head and was skeptical on buying this cause personally I know most brands and how they sound. I never bought Logitech because its not really high end. But after buying it and trying it out, I'm actually impressed. It can be loud with no distortion and bass clear once you set the level properly. The bass on this sub is pretty good, it can hit 98% of the notes, but for the price you can't complain. A song with good bass, this sub would shake my desk and ceiling panels in my office. Would I recommend this to a friend? I sure would if they just want something cheaper and with good sound quality. I would give it a five star if it had multiple inputs more than what it has now like optical in for my PS4. Other than that, good job Logitech, you changed my view on your products.

  • from Coquitlam, BC

High-performance, Powerful and reliable at a good price!

Thank you Logitech...You are one of the best as always.

  • from Moncton, NB

worst audio system ever

completely unbalanced , subwoofer over powered for the satellite with a rumble bass. The highs are not rich in quality. I just have a cheap Edifier 2.1 system which delivers super high rich sound quality and well balanced with the sub effect. Don't get me wrong though , this thing is loud BUT if you look for sound quality this thing is 5 on 10 for me anyways.

  • from Barrie, ON

GREAT Speaker!

I purchased these speakers a few years ago and I love them. The are the replacement for the (now really old) Z2300 and overall I prefer them. They have a smaller sub and generate slightly less bass but the satellites are far more clear. They don't crackle or have any issues when turned up and haven't given me a single issue even after years of use. On sale they are a great bargain and one of the best you can get. I am very happy with them!

  • from Browntown, On

Best Speakers Ever!

got these for 129 Canadian, making it almost 150 with taxes, but let me tell you this was the best 150 I have ever spent. They sound awesome. Don't think twice about getting them if they are on sale.

  • from Sarnia, ON

Nice speakers for the price.

For the price these are good speakers. Loud enough, with enough bass from the sub for smaller rooms. Any more and your neighbors will come knocking. If I Blow these out playing them on high blast all the time I will still buy them again, but Best Buy has protection for 2 years so buy it and crank them up and rock on!

  • from Montréal, QC


awesome for hockey rooms and parties! Don't overuse it though or it will burn out

  • from Richmond, BC


pretty nice all around

  • from Oakville, ON

a good fight

i really like the feeling of music. after 2 years with this system, the volume was mostly on full. nearly got evicted from the sound being to loud. but once you go loud, you dont go back. now my speakers are always on full and to me, their not loud enough. regardless its good what you paid for

Logitech Z623 poor on quality for Power Button

As one other person mentioned earlier (Mar. 2017) I also bought my system a year and a half ago and because of the power button the system is of no use to me. Very poor on Logitech's quality control system. I hope to replace it today (Thursday Aug 3, 2017) as it is still within its warranty period. This should not occur. Luckily there is the 2-yr warranty period in our (customers) favour. Thanks MH

  • from edmonton, AB

great i think

i havent bought or even seen these speakers but they sound cool

  • from Thornhill

High quality speakers, but with defects

I've had these speakers for a year and a half, and they are fantastic quality. Great clarity and rich bass. The extra jacks on the right speaker are super convenient, although it is quite difficult to plug cables into them because you have to push very, very hard. The biggest problem for me is the defective power button. Occasionally, I will have to turn off and on the speaker when I power on the speakers because of crackling. The power button is also very sensitive, so any brushes against it will cause crackling. I am concerned that the power button might break in the near future.

Too raspy of a sound - harsh unlistenable

I have bought many PC speakers including nice Logitech brands, so I thought I would now go all out and get this super larger model with the big bass box with bigger midrange/tweeter satellites and even the nice controls. I was hoping for a bigger better sound than my smaller Logitech. What a disappointment. I tried so hard to like them, but the raspy overpowering harshness of the satellite speakers was just horrible. I was so disappointed and I eventually returned them. I am shocked at the higher ratings. I did not want to chance another pair.

  • from Ottawa, ON

All PC Speakers

FYI... All pc bookshelf speakers that have a rating of 200watts (like this model) or even at 100watts for that matter is a "gimic" to get you to buy them. I've been a sound and lighting engineer for international rock and pop bands for about 36 yrs. About 99% of pc speakers have a top max wattage of 50watts... and that's pushing it. These speakers are about 18watts each. Let me explain... when a DJ performs at a small party he/she brings in speakers rated around 150 to 250watts. These have enough sound to fill a good size school classroom with enough volume to satisfy most. These pc speakers barely fill my bathroom with sound. When pc speaker manufactures put 'wattage ratings" on the speakers, they are actually trying to impress you by saying they are 200watts. These speakers are great for what you'd want for your pc, but won't give you anywhere near 20watts or even the "rated" 200watts claimed. Next time to look at pc speakers specs, do not buy just because of the wattage rating. Go with with the formula of 100w divided by 10 = 10watts. Or 200w divided by 20 = 20watts. Look for pc speakers that have a min 4" or larger inches subwoofer and the tower spkrs that have a mid and high spkr in the enclosure. Any pc speaker system that comes with a sub will be your best set-up. I own "Logitech Z-5500 THX-Certified 5.1 Digital Surround Sound Speaker System"

Worth Every Penny

I was surprised by these speakers. I wasn't looking for anything particularly powerful but I did want something that would reproduce crisp notes on the high end and enough bass on the lower end to not "Sound like" bookshelf speakers. I put my faith in the THX label and bought them on-line. I use these in a home office environment and listen to them mostly while working. Well, they sound great and faithfully reproduce all ends of the music spectrum. Having power and bass buttons on the speakers themselves is a nice touch that I use more than I thought. As for power, I rocked them on the first day. I was more than impressed as they actually moved the pictures on my wall - enough said.

  • from Shawnigan Lake, British Columbia

It Was Great For A Few Months.

I bought these for my computer about a year ago. The sound quality is phenomenal and the bass is amazing! The only thing I don't like about these speakers is that the buttons wear out fast. After about four months I have been having to wiggle the power button to make the sound work, the bass nob sometimes sticks, and when I turn up the volume I can hear static coming from the speakers (when there is no music/sound). Other than that, it is a great product and I am still very happy with the purchase.

  • from MTL, QC

Had to replace 3X

There's no reliability despite the great sound. Ive literally had to return them 3x for the same issue, sound distortion, and now the sub has completely cut out. Its a bit ridiculous.

  • from Toronto, ON

Maximum volume is not loud enough

Good sound quality but the maximum volume was just acceptable. The sound was not loud enough as compare to the previous Logitech model with the same power output of 200W RMS.

  • from Brampton, ON

Best speakers for the price

these are really good speakers the best at their price but probably would not buy them at full price as i waited for a sale otherwise best speakers for the price

  • from Victoria, BC


I've never really been a fan of Logitech, but after reading the reviews online i decided to try them out. Best speakers I've ever use, no joke. Got them at a good price via black Friday, and they have very deep bass, convenient knobs, and good mids and highs. I did notice a slight whine when I first bought them, however it went away after a day, and I only heard the whine because I was looking for it. Well, listening for it. Not sure why, but yolo. Definitely worth it.

  • from Halifax NS

Love them! Just bought my second pair

I've owned a pair of these for about six years. Well they've had beyond what I'd expect speakers to last for usage. From lots of parties to lots of days cranked for hours on end. I can't say there's been many times it's been past 75% as it's way too loud. However they've stood the abuse and test of time. They are amazing for bass and sound. Hence why they died tonight and I went and bought another pair. For the people who talk about a high pitched whine, any speakers get those with interference from radio or wifi signal. Also if you have the cable in the back hooked up compared to the side of the speaker there's a proper way to do it. My only complaint is I'd like an hdmi hook up for gaming, but these are computer speakers and as great as they are it's not a surround sound unit. Overall I'd buy these again and did. Amazing especially for the price!!!

  • from laval, QC

the best

bro get this u need them their good in every way, shape or form.best ones i'v ever seen in the world.:)

  • from montreal


amazing speakers no complaints

  • from Port moody

Best speakers

One of the best speakers of Logitech I have seen. I have had them from 2 years and works amazingly perfect. Would definitely recommend.

  • from Calgary AB

Awesome Sound

Great sound with clean bass. Any genre of music sounds great with these speakers. Pretty much the best speaker system you can get at this price point.

  • from Halifax, NS

Wow wow wow!

This is a fantastic system! Have a Z2300 in the kitchen and wanted something comparable in the living room. The Z623 more than delivers. Great pounding bass (if you like it like that) and incredible all-around sound. Love it!!!

  • from Milton, ON


I couldn't believe just how awesome this set is. The clarity and the bass is just insane. I would absolutely recommend these!

  • from Victoria, BC


It emits a very high pitched whine no matter the volume. Well known defect on online reviews. Do not buy.

  • from New Liskeard, ON


Best computer speakers for the price, if you're a base lover those are for you! You sure can disturb the peace with those speakers.

  • from Victoria, BC

Amazing sound!

Replaced some 10 year old JBL speakers with these monsters... very clear, crisp, and DEEP bass. Love them.

  • from Hamilton, ON

High Pitched Whine

High pitched whine comparable to dog whistle when speakers are turned on. Whine does not change in volume when you increase so you can listen to music nicely at a high volume, but very annoying at low volumes.

  • from Victoria, BC

Almost perfect

The sound quality is phenomenal as is the volume that this system can generate, my only complaints are, the knobs are hard to read because the levels are black instead of white. Not a big deal though so I just painted them and the speakers don't come with regular speaker wire so if the amp goes the whole system is useless but other than these two minor quibbles, these speakers far exceeded my expectations.

  • from Ottawa, ON

Very good

I've had these for a little over a year and I use them frequently at very high volume. They perform VERY well for the price. I tend to blow speakers frequently but these ones just wont blow. The subwoofer cant handle certain songs above half bass volume, if you have the main sound turned up. You will hear it struggle sometimes... but seriously you dont need it on a very high volume, its plenty loud at half volume. It shakes the house at half volume. The ONLY thing that has gone wrong with these is the power button, sometimes if i hit it when reaching for the volume knob, the subwoofer cuts out. It;s not a big problem they still work great! GREAT for music movies and games! Dont think twice about these, they are AMAZING for under [Price]!!

  • from Lethbridge, AB

They sound great

The speakers sound great with computer. Bought a second set for future TV use.

  • from Toronto, ON

Absolute value for money

Great for home, small-medium rooms, also can work in a large hallway but would prefer higher RMS speakers. Works best when paired with a THX sound card like Creative Sound Blaster. I also have an SP-2500 from Corsair, compared to that these are of great value for money. Sound is clear, rich, good bass and clear vocals. Don't think too much, go for it.

  • from Saskatoon SK

I love my speakers

I listened to a set of these in Future Shop 5 years ago and fell in love with them. A few months later they showed up in the Boxing Day flyer at a price I couldn't resist. They are the best computer speakers I've ever heard.

  • from Saint-liboire, QC

Best 2.1 for the price

Good choice

  • from Calgary, AB

Best Boxing Day Product!

I bought these speakers online during BestBuys Boxing Week Sale. They were scheduled to arrive 10 days from purchase date but arrive in just 5 days! This gave me some more time to try them out before I went back to work. I was blown away by the clarity and power! I'll be watching the BestBuy ads if and when they go on sale again. I want another one for my computer downstairs.

  • from Toronto, ON

WOW!!!.. Just WOW!!!

After trying other speakers from a competitor at higher price..and having to return twice in a week because of defects. I decidided to cut my losses and shop at Best Buy. Researched this item and reserved it for p/u at store. Amazing sound and everything!.. with Bass set at even it soun ds far better than any thing the competitor sells. If u use ur speakers for listening to music with a good bass beat.. get these.. U won't be disappointed!

  • from Laval, QC

Awesome Speakers for the price

These speakers are freaking awesome. Thumping bass, awesome sound quality and great for music and games. The cable for the right satellite speaker is pretty short, but that doesn't matter much since they work well. Overall best purchase I have made aside from my pc. I would recommend these to anyone who loves clear sound and thumping bass.

  • from Mississauga, ON

Awesome speaker package

just bought these today at the boxing day sale speakers sound really good and the bass really pounds

  • from Markham, ON

awesome setup!

Bought these on boxing day, they sounds incredibly good. Cant believe the sound that comes out of this system. Would recommend to anyone. Over the top.

  • from Etobicoke, ON

Great sound

I wanted to buy a nice 2.1 speaker system and after much research I finally decided to buy the Z623. When I first powered them up my heart sang with joy after I heard the heart thumping bass and the crystal clear sound. After a couple of days I realized that the right speaker with the controls on it didn't work when the volume was turned low. Only the left speaker worked. After reading similar problems on various forums I learnt that it is a defect and is not a design issue that some users thought. I exchanged it for a new set and these work perfectly. Balanced output on both speakers at any volume. So go get these and have a blast... :)

  • from Brampton, ON


These speakers are good but not great if you listen to a lot of bass heavy music its good but at high volumes its distorted and the bass isn't that good

  • from Toronto, ON

Great speakers

These speakers ROCK! For the price there is nothing out there that compares. I got these on sale and I so glad I did. I highly recommend these speakers, they have high quality sound and the bass is amazing. I give this product 5 stars in all categories. HR

  • from Victoria, BC

Error in the design

I'm very disappointed with these speakers and I can only advice everyone to stay away from them. Basically as soon as you turn the volume down the right satellite actually becomes so quiet you cannot hear it anymore while the left speaker is still quite loud. Only when the volume is above a certain level both speaker will actually be at the same sound level. First I thought I got a defect product and I exchanged only to encounter the exact same issue on the new one and apparently the error lies in the actual design, because the left speaker is on a regular audio jack while the right one has a fancy plug to support the power, volume and bass adjustment. In short do yourself a favor and get a different set.

  • from London, ON

Nice full sound

Little pricey but good power.
