Logitech Z623 Computer Speakers

I'm sorry to all those uninitiated people writing these "reviews" of the Logitech systems. Logitech make about the worst, muffled, shabby and terrible speakers I've ever heard. The Z623 sounds muffled, inaccurate, terrible. It sound like it is encased in concrete, and all I can say is if any of these reviewers heard the Neumann KH-120 mkii Studio… Read more

Monitors back-to-back with the Logitechs then they'd know what I am talking about. Or even just a little Audioengine A2+.

The ONLY thing these speakers have is a big subwoofer that produced (relatively) deep bass, that is the only thing they have going for them and the 2 stars is for the sub, not the satellites.

Heck, these speakers do not even have tweeters! The treble is grossly over-EQ'ed, and sounds dreadful.

The problem is these reviewed have no idea, and are used to $35 plastic computer speaker boxes or other cheap rubbish. They just hear how deep and extended the bass goes, and on that alone, decide these sound great. They do NOT. One dead give away these reviewers have no qualifications: There is no such thing as "THX certified speakers" at all - that is just a marketing ploy and means nothing objectively in the world of analogue and digital electronics and acoustics. Every aspect (bar the sub's large cone) of these Logitech speakers is wrong, horrible, and results in terrible sound, which is also so muffled that we can't hear it's full putrid expression. How anyone thinks these are "crystal clear" is beyond me.

Granted, these are very cheap speakers, and you get a sub for the price, but still so sickly that I would not touch them. Look elsewhere, even if you have to spend more money.

Buyer beware.

Still sounds awesome many years later! – I purchased these speakers about 8 years ago and they still sound as good today as they did when I bought them... even with almost daily use for almost three years. Love the ability to adjust the volume/bass on the right hand speaker - great when you want to quieten things down a bit - or crank up the bass for a thumping tune! Headphone jack on… Read more

the same speaker could also be handy for some, not that I have ever used it.

I used these at an event in a medium size function room and they did a great job. Never really have them past the half-way point but there are LOUD when you need them to be.

Before deciding on a comparison with a cheaper speaker set, compare "200 watts RMS of power" spec of these speakers (noting "RMS" is important, as some good marketing uses 'peak power' to make their speakers sound like they are better). If loudness/bass level is important, choose a higher RMS wattage.

For my general home use, listening to music, YouTube etc., these are still perfect and highly recommended. Love this product!

A review by a partially deaf person who understands your incessant need for level bass – TLDR: Overall, this set is good for movie nights, surround sound, small gaming set-ups, and casual music lovers. While it it fantastic value for money at such a low price ($170.00AUD avg.), don't expect a high value range of bass from the subwoofer, crystal clear mids and high range tones, or exact timing in between the two satellites when they're… Read more

further than 2.5 meters apart.

Pros:

- Quality bass for such a comparatively small subwoofer.

- Bass control paired with volume control seperate from the input control (PC/Tablet/Phone volume and equalizers) makes for a nice even balance when you adjust both accordingly.

- During music play, heavy bass does not offset lyric or disrupt mid tone quality which is a common problem in many headphone and small speaker sets.

Qualities:

- Performs clearest tones when using lower volume. Bass is best felt using higher volume. Best in-between is having the volume knob turned to a third to it's max. and the bass knob turned just a touch past it's middle click setting. (The middle click setting for bass control is also incredbly useful for equalizer adjustment where possible)

- Small workaround for a too short aux cable is plugging it in straight to the headphone jack on the main satellite from your input control instead of to the subwoofer depending on your setup.

- THX certified peakers guarantees quality surround sound and rumbling bass during all the best Sci-Fi movies.

- Drums and gunshots in music and gaming are heavy and solid, rather than hollow, sharp, or uneven in volume.

- In my personal opinion, this set is best when dealing with drums, strings, and hard bass.

- Is surprisingly steady during low bass rumblers with sharper high tones. If you want to test your speaker's ability to manage this, make a small playlist of mainly rumbler tone bass songs, mainly sharper high tone songs, classical or intrumental songs, and some mixes of rumbler mids, sharper lyricals, plus a good set of all three. This will let you know how well your speakers can handle a muddled mess of strong bass, tweeter stress, and warbling mid tones. I've made a playlist on YouTube here to test your speaker quality:

https://www.youtube.com/playlist?list=PL11kj3mMdPms2lJpbhOH_SUDQKKIPK_4s (remember, you don't have to like these songs and you certainly don't have to use this as an example, this range test will work on any speaker set including headsets, these are not subwoofer range tests, only 'stress' tests under normal use)

Cons:

- Some mid-low tones (higher bass buzzer tones) are not the strongest asset of the subwoofer. Try to steady your equalizer (where possible) to give your input bass more oomph and fiddle with the bass knob on the main satellite for a while to get the best bass quality you can from this set.

- Input can be fuzzy. When plugging and unplugging the aux from my laptop the speakers made horrendous popping and buzzing noises until I stopped adjusting the cable. (This is unnecessary when the cable is left alone)

- Even while the aux is not plugged into an input there is a low buzzing noise emanating from the speakers. (This problem may be solved by using a longer, gold-plated aux cable rather than the one included)

- As with most bigger sized PC sets, the subwoofer is touchy with it's placement for best quality use. If you plan on using these speakers for music or movie set-ups, experiment with your subwoofer placement and run a bass heavy song while wandering around the room to see where the bass resonates with the rest of the immediate area. This will give you an idea as to where is best to place your subwoofer depending on how big the room is, where the speakers and subwoofer are placed, where you will be watching/listening to something while using the speaker set, and where you want your bass focused.

Subwoofer great, satellite speakers bad – The bottom line of this speaker system is the subwoofer alone at the price would be good value for money. The problem is you can't use the subwoofer with anything other than the satellite speakers as it uses a fixed non-modifiable wiring system meaning that you're stuck with what you buy, unless you're willing to deconstruct the satellite speakers… Read more

and rewire them to decent speakers, [update: when the unit went out of warranty, I did deconstruct the unit and added two fairly high quality speakers. It is now has really impressive sound with an incredible base with the subwoofer. As for the crossover I was worried about (next), there were no issues] and even if you did this, the crossover to the subwoofer maybe too high and is unadjustable. When listening to the satellite speakers alone, they sound like an average set of Notebook computer speakers, however they are much louder. The middle upper too high range is not so bad but they lack terribly in the mid to mid lower range, meaning that they don't bridge the gap between speaker and subwoofer. This is not that unusual in this style of satellite/subwoofer speaker system and is really disappointing, because if they did, they would sound spectacular for the money. There is one advantage in that, because the speakers are relatively small they will fit quite nicely on a computer desktop. As far as what's available as computer speakers in this size and price range, there honestly isn't anything that's likely to do much better, and if you're just after a wicked base you'll be happy.

The speaker system is designed mainly for computers, I bought them to listen to music. It will probably sound good when listening to movies on a computer, especially those like the Pacific Rim that have a lot of low rumbling base effects. There's also plenty of volume, so much so that you could easily annoy your neighbours. If you're not musically fussy like I am (if I had the money I would buy a $50,000 audiofile system) you'll probably be happy with this system. It stills meets the Logitech, good value for money criteria. If you're into any kind of music that fits into the doof doof profile of music, don't buy them, however you'll have to spend a lot more money!

It's so good I have never ever considered a replacement – I've had a Z623 since - apparently - forever. I can't remember a time before I got this. I can't imagine being without it. Its bass is thumping, when it should. Its satellite speakers are clear and strong. It has an accessible power button, and volume and bass dials if I ever need to use them. It's one of those products you use every day,… Read more

enjoy their quality, and never think of upgrading. Invisible goodness.

It's so good.

If you constantly and happily use a product with no complaints it's a sign that it is great.

The Z623 is great.

The bass is thunderous and they are good speakers but for general use possibly require a bit of tweaking – These speakers are good for watching movies on the computer. Quiet they are not and I like it that when you listen to the "THX Sound Effect Remastered HD" noise on YouTube you can really feel it in your bones! At $140 they are the most expensive computer speakers I have ever purchased but I am still happy with my purchase. Room for improvement: -… Read more

There is a bit of hiss when they are on. This may be due to the quality of the audio output of my computer!? - The balance is a bit bass heavy for general listening, but I was kind of expecting that and it can be tweaked. - Slightly longer cables would have been helpful (an extra 50cm - 100cm on all would have been perfect).

surprised !! – Very engaging at close range such as a desk with tremendous and accurate bass especially for their size. Better still if you have a wooden floor which can load up the low frequencies, from what I read they go down to 30 Hz Also if you want your desk to rattle place the Sub at the front of the desk but make the port fire under the desk for a… Read more

quasi horn load effect, its amazing

I once used them as party speakers in the yard playing festival trance and they neighbors, came over looking so see what kind of PA I had rented. Try them outside on the patio and you will be surprised .

My regular system is a Luxman and Dali Setup and most times I prefer listening to modern music on these baby's.

They're not made for classical or other complex natural instrument arrangements but there's not much modern material made that way any more anyway

To top it off i got them for like $65 dollars at office works on a sale

High Frequency Crackle – Arguably the worse speakers i have ever purchased. High end static/crackle that infuriated me, so i bought a $38 set of Armaggeddon Panzer III speakers from Kogan, The sound is 10 fold better from the Panzer for a fifth of the price. Truly disappointed considering i generally like Logitech's products. Not even worthy for the shed. I've heard better sounds come from my bum then what is emitted from this rubbish. Show details

Great budget speakers – Wanted some $100-ish powered speakers for PC got these for $118 normally $198 Officeworks had them for $144 & price matched + 5% less = $112 these do have a good sound .. for the price I paid, .. they more than suit the purpose for PC work but not for use as secondary home theatre speakers

Logitech Z623 - A Short Life For Expensive Speakers – The Logitech Z623 looked like a good idea, from the outside, for a long term investment, but as soon as the warranty expired, so did the speakers. So well timed, that I am thinking that perhaps the product had an automatic self destruct device included. I would have least expected 5 years for the price. One year is just ridiculous. I was better off buying cheaper speakers, if they're only going to last one year. Waste of money.

The sound is fantastic! Clear, crisp, and really fills the room. The bass is strong without being overpowering, and setup was super easy. Perfect for music, movies, or gaming definitely worth it!

The sound quality is just incredible deep, punchy bass when you want it and crisp, clear tones from the speakers. The controls are easy to reach and adjust, though I rarely need to. It’s one of those products that just works perfectly every day.

It thumps! – Had this for more than 5 years now and it's still impress me. I was a bit worried about their claimed 200W RMS until I plugged it in. So much bass, great for Hip Hop and RnB music genres that requires lots of low end bass. And it costs less than $200! Look out for specials with these, tempted to buy another one for the shed. Show details

Excellent speakers, incredible price – I bought these speakers over a year ago at Officeworks. They are really great and I am so glad I bought them. The sound is really good on video and music. The volume is so good that I rarely need to use more than about a quarter of the maximum when I listen to video and I only need half the maximum with loud music. I bought them for $95, which was an awesome price. They are definitely a step up from my previous speakers. Show details

Bang for your buck – These speakers are amazing for their price. The bass is booming. But I love that you can control the bass volume as well as the normal volume separately. It makes finding that sweet spot easy as can be. And when you pair these speakers with a Bluetooth audio adapter. Its just phenomenal. And the price! So cheap for such great sounding speakers! I… Read more

use them for music, movies, tv shows, YouTube, gaming. Literally everything and they are just so great. I have had my speakers for almost two years now. And I have had no issues with them thus far. If you want reliable and great sounding speakers for a good price. These are your best bet.

made to cure a headache....not – A great set of 2.1 speakers and sub-woofer. Excellent bass and crisp clear mid and high tones. Can't go wrong with these for the price. The way the bass operates adds a real cinematic dimension to viewing. Show details

Sensational – bought these recently from Officeworks and they are sensational. The high-quality sound that comes from these is astonishing. It almost mirrors a quality hi-fi system and for the price, you won't be disappointed _ this product comes with a high recommendaion Show details

This product is perfect – Brought them about 4 months ago and loved them ever sense, i originally decided to go with them over the newer ones because of the reviews that i already read, now im happy to say that they were totally worth it even being an old model the sound itself is great and the bass is awesome, i barely even need to have them up anything over a quarter to hear them Show details

Loud and Clear – These speakers sound fantastic on my desktop iMac. The bass is heavy and the actual volume is very loud. I rarely have the volume > say 6. There is the option to attach an external device ( eg: mobile) and play music etc other than the iMac ( in my case). The subwoofer/connections box is quite large so you need to have space to cater for the… Read more

hardware. I picked these up on a price match at Officeworks in October 2018 for only $114.95. Very impressed.

After reading all great reviews, I decided to buy these instead of a soundbar for my TV. No regrets – I've been through a few soundbars that I've never been truly happy with, Samsung and Panasonic where the most recent. They were fine.. but these THX certified speakers from Logitech destroy them! They are better than the 3.1 system I had from Panasonic purely going off how good it sounds in movies and games. I've never owned THX certified speakers - you can tell the difference straight away, no doubt. Amazing for the price, you will love these.

Astonished for the price – Crazy sounds coming from a $100 system. Bass shakes my wall/floor if you crank it all the way up! As for the satellite speakers, they sound quite decent. Bit of lack in the mid range but most people should be more than happy. Definitely sounds clear and watching movies is a blast.

Logitech Z623 speaker system – The Logitech Z623 speaker system is phenomenal. The sound is crisp and clear. There is no word to describe the base, short of incredible. These speakers sounds like I paid a whole lot more than I did. Big thumbs up.

Great sounding speakers at this price – I used to own some previous Logitech speakers (Z2300) and I was very pleased with them. I bought these speakers at a bargain price for around $100, I think. For the money, they are great sounding speakers. Not sure if they are as good as the Z2300's, but still pretty good sound quality. They are loud, have plenty of bass and I am very happy with… Read more

the sound quality. Why would you spend $30, $50...whatever on an awful set of cheap, tinny, bad sounding speakers when you can get these with a sub-woofer for this kind of money?

Disappointed – After reading all the rave reviews on line I went out and bought this speaker system thinking It would be a bargain for the price, I'd be able to listen to decent sound quality on my TV and music from my phone. But you get what you pay for! I think if you want quality sound you need to spend around the $1000.00 mark.

Great sound – Purchased a set of these speakers in April on sale for under $100 from Bing Lee, to go with my (then) new desktop PC. Both the wife and I have been pleasantly surprised with the quality of the sound the speakers and sub puts out. My only complaint is that the cables are a tad short, but if you can get a set for under $100 like I did, you'll be hard pressed to find anything better at that price point.

Too good guys. Just go and buy! Dont think twice – I have bought these speakers in 2013 and still going great. - sound quality is just great - bass is very good - the only small thing to know is, it doesn’t have remote but the price and quality is too good and can certainly ignore this point.

Great sound, except position of cables – It's easy to setup and had great sound quality however the cables coming out of the sub are on the left side compared to the older ones i've had that come out the back. This makes the unit wider than it should and not it flush against the left side..

Excellent value for money – I currently use this as my main audio output for my media setup. Music is loud and crisp, the bass is punchy and the THX certification is a welcome feature to any Nolan fans. I picked these up relatively cheap and since they run directly into the 3.5mm jack on your TV, there’s no need for a dedicated remote.

Perfect Speaker – Excellent speakers. The bass is amazing and the sound quality is great. The addition of a aux port on one of the speakers is also incredibly convenient. Only not so good side would be that the subwoofer is incredibly large. But given that these came out so long ago, I suppose that's to be expected.

Heaven Sound – Purchased during Christmas for my son listening to the music and watching cartoons. The 2 years old definitely love the sound and keep clapping and laughing. Very good product with very good price.

Quality Sound, lots of power – For 2.1 sound out of the PC, these speakers are worth considering. I purchased these last summer and they are fantastic. Love the sound quality. More output power than you need for a PC as well. I have also used this product as stand alone speakers for my DVD player. As these speakers only have an analogue input, I used an HDMI Audio… Read more

Extractor. A low cost item available on E-Bay.

Would highly recommend these speakers however you must shop around. They differ in price here downunder by approx $40AUD.

Great speakers for money – I purchased these speakers to upgrade from old Logitech computer speakers with static noise. I am really happy with them, bass is great, speakers have great sound quality. To be honest i was not expected them to be this good seeing I only paid $130.00. I purchased them from Officeworks tax time onsale for a bargain. Crank them up and turn up the bass with no distortion. Great for PC games or music.

Logittech Computer Speakers – When I bought these Logitech speakers for my computer I didn't know what great sound I would get ,They are great the bass is really great and crystal clear sound .I have purchased these speakers again for my smart phone and tablet

Really good speakers – I had to buy this speaker because the sound level of my laptop is very low. It has good playback and is economical. If you are not that into high end audio devices, this works fine for everyday use.

Great for Price – Considering its price point it's a great product. Highs and mids are great for streaming music and definitely has a lot of bass. Show details
