Logitech Z623 THX 2.1 Speaker System with Subwoofer, THX Certified Audio, 400 Watts Peak Power, Deep Bass, Multi Device, 3.5mm & RCA Inputs, UK Plug, PC/PS4/Xbox/DVD Player/TV/Smartphone/Tablet, Black

I've owned a set of these speakers for about three days and felt I had to post a review because I love them soooo much !! I own a 27 " quadcore imac, which I love, but whilst the inbuilt speakers are OK for general low level listening, especially late at night...they are not much good for anything else (they do give a surprisingly good stereo image, but bass is non-existent and Apple really should build in something far better to preserve their image and reputation for what is already an overpriced PC !!!). I wanted sound to compliment the specs of the rest of my system. I also wanted sound that was sublime for music, films and games. As far as I'm concerned, in this tech-age, this was not a big ask. However, when I researched my wishes, I was confounded by how the reviews for each product could vary quite widely. I didn't just read the reviews on Amazon, but I also read reviews from magazines et al that were posted on the net. At least two of these reviews almost deterred me from buying the Z623s. Of course many other reviews on Amazon encouraged me to consider them strongly !!! The reviews that put me off suggested the speakers were great for TV, films and games but poorly balanced for music. However, when I noticed a market place seller on Amazon advertising this system in used condition but with a 3 month warranty at virtually a third of the Amazon price, it was a no-brainer to buy them (as everything else I considered also had at least two poor reviews also, but at a much higher price !!!). The speakers look ok-ish...I'm not a great fan of the shape of the satellites and the 'Logitech' logo on the left speaker doesn't compare to the more impressive THX logos which feature on both speakers. Apart from the shape (which could be something that only I dislike...a question of personal taste) the speakers do look expensive and substantially made. The subwoofer is not overly large, so it's ideal if space is at a premium and again its construction looks substantial and expensive. As far as performance goes, I will cover: TV, film and game performance first. Basically faultless. So many expensive flat screen TVs these days boast superb picture quality but come with absolutely pathetic speakers. If you are the owner of such a TV, add these speakers to your screen and you will be in dreamland. Similarly add them to a DVD player or games system (PS3, Xbox 360 etc) and you will be more than satisfied. Of course you may want to go for a 5.1 surround sound system (understandable as I also have one of these but downstairs with my TV) and I am only rating this system for those of you who want a 2.1 system. I wouldn't compare it with 5.1 systems, although I would suggest that you will achieve similar clout and ambience here with far less hassle (took me ages to balance my 5.1 system properly !!!) I have covered TV, film and game performance first because I have not found a review of the Z623s that in any way suggests it is a poor performer in these areas. I will now cover music performance of these speakers and in more detail, as this is the area in which some reviews have down-rated this system. Firstly, I will state that I am not an audiophile, but I am very fussy as far as sound quality of audio is concerned. The main type of music I listen to is 70s progressive rock (please don't yawn !!!!), however, my musical taste is very wide and also takes in drum n' bass, dance music (R&B + Ibiza etc etc), top 30 chart music, folk, classical and pretty much everything else except for maybe trad jazz. I listen to my music mostly from apple lossless files on itunes (created from my personal CD collection), 320 kbps mp3 files downloaded onto itunes, anything on youtube that takes my fancy, 'spotify' with high-streaming quality (and of course 'progstreaming' !!! LOL). I use the equalizer on itunes to perfect the final sound output but I do not tailor the sound from youtube or spotify (hopefully though, spotify will have an equalizer for mac soon as there is one for windows....). Music from all these sources sounds equally good... Drum n' bass, chart music, dance music of any description is again a no-brainer with this system, you will love it !!! Pleasingly for me (at least !!) prog rock also sounds superb, folk and even classical music sounds as it should with this system. I am also relieved to add that all types of music sound superb at low level as well as at loud volumes. I guess the louder volumes sound slightly better , but I am certain that would be the case with any system I listen to. The soundstage oozes quality and is incredibly well balanced, whether at high or low volume. At high volume you will make the house vibrate whether dance music or heavy metal is your vibe - easily loud enough for any serious party. At low levels you will still hear a beautifully balanced soundstage that sounds immaculate. Whilst I repeat that I'm not an audiophile, anyone who has reviewed this system as being poorly balanced with music, needs their ears washing out !!! Some have stated it sounds tinny at low volume with low bass - this is definitely not the case. I have been dipping into my music collection with renewed vigour since I have bought the Z623s, as everything sounds soooo good !!! Most tracks I listen to I want to repeat again and again, as I enjoy hearing them in this sublime Z623 rendition so much !!! I would add that it didn't take long to set up a good sound stage either. I recommend positioning the sub somewhere underneath the two satellites and more essentially make certain that the port on the sub is close to a wall. If you place the sats on your desk, the control for volume and bass level is always within reach, which is ideal, but I have anyway found that even though I flit between differing musical genres and programme sources, I rarely need to adjust things once I have decided the volume level appropriate for any particular audio session. There is an extra 3.5 input with the system and also an RCA phono input, which makes it all the more flexible. (I also use the system for recording music from guitar and keyboard into garageband on my imac - again it is great !!!) There has been a question of reliability raised with some reviews. My second-hand pair perform superbly. I will update my review immediately should any fault develop with them - so take it as read that my used pair are still working fine unless an update is added to this review !! I will conclude by saying that if you live in a flat or even a semi-d these may not be the ideal speakers as far as your neighbours are concerned !!! If you can't resist turning them up, they will disturb your neighbours badly. Whilst I live in a detached house, I have to trim the volume and bass levels when the wife is in !!! My preferred sound levels would never disturb the neighbours but they can easily resonate throughout the whole house even at modest volume levels (which annoys her !!!). That's why I'm glad to contradict the odd bad review and confirm that audio still sounds the bizzo at lower volumes, so I can listen to my Z623s in peace literally.....

I have previously had an Onkyo HT-X22HDX which I sold a while back when I was short of space and was recently using some very small and thin designer style Logitech speakers that cost around 40 GBP. My cheaper Logitechs were quite impressive given how ridiculously thin the speakers were but they could be tinny and distort at times. My new Z623 speakers are very impressive and are every bit as good to my "consumer" ears as the Onkyo which cost twice the price. I use them for my PC and they are overkill for that task and won't distort at all at any volume I'd dare use when sat this close to them. I have a very large monitor and use my PC for everything from gaming to movies to TV to music. I'd say they would also be more than adequate in an average UK sized living room or bedroom for someone wanting to use them with their TV or games console and would no doubt cause huge annoyance to neighbours or parents long before they reach a volume where you would experience distortion. They are more than just "loud" if you know what I mean. There is so much more detail than on my cheaper speakers or the ones built into my 40" Samsung TV. The sound to my untrained ears is very deep and rich with a lot of crisp detail on the higher notes. This means you can kind of run them at a lower volume level and still pick out everything. Granted I am no audiophile but they sound absolutely awesome when playing games, watching movies or listening to regular music. I have a pretty good sound card in my desktop PC and to be honest you can dramatically alter the sound just playing with the settings on that so I am sure if anyone did have issues with certain aspects of the sound then it is probably something they can tweak themselves to suit their tastes. I have no concerns about the quality as my old Logitech speakers must be four years old now and have been shuffled all around the house, dumped in a carrier bag in the spare room with junk piled on top of them and even stored outside in a shed at one point but still work fine. The volume control being on the right hand speaker makes them great for PC use and to be honest the old wired remote on my previous speakers is kind of pointless as you are hardly going to drape a big thick wire across the floor. So I like these because they have less cables than those systems with a wired remote. It would be nice if they had a proper remote control as then I would recommend that everyone buy a set to use with their TV. At this price and with this sound I'd still recommend it if you don't mind getting out of your seat to adjust the volume.

Clear and distortion free, even at high volum levels

Uzun süredir aradığım ürün dü. Gayet güzel beğendim. Sorunsuz ürün 😊 Bu satıcıdan daha önce alışveriş yaptığım için hemen aldim. Satıcıya teşekkür ederim.

Received it and functioning as described. High-quality System, all components looks elegant and looks nice in the room Bass Control is available Bass at low volume is so intense and great. If you are browsing which 2.1 Logitech Sound system to select, I would recommend this one for the high Subwoofer and Speakers 400 Watt. Connections are all wired, however to connect with Bluetooth devices, I added Logitech G Wireless Bluetooth Audio Receiver/Adapter, or you may purchase alternative Bluetooth Audio Adapter.

i set it up on my PC for multimedia and gaming. totally worth it. sound quality is good. bass is strong in this one.

le son est bon, là dessus rien à dire, mais quand même ,c'est cher et le cordon d'alimentation est US, heureusement, il est amovible et peux être changé. je l'utilise pour remplacer mon ancien système audio tv qui à laché. le caisson de basse est gros mais comme il est caché derrière la tv, ça ne me gêne pas. le câble jack coudé fournis est une bonne idée et très utile. je ne l'ai pas poussé à fond, car à 70% déjà, les murs tremblent et je ne veux pas la guerre avec les voisins, ça semble puissant en tout cas.

Das Logitech Z623 Lautsprechersystem mit Subwoofer liefert, was es verspricht: satten Bass und eine beeindruckende Klangqualität, die ihren Preis definitiv wert ist. Zwar wurde es mit einem UK-Stecker geliefert, was zunächst ein kleines Hindernis darstellte, doch mit einem einfachen Adapter vom Mediamarkt war das Problem schnell gelöst. Die 400 Watt Spitzenleistung und THX-Zertifizierung sorgen für ein Sounderlebnis, das über die Erwartungen hinausgeht. Ein hervorragendes System für jeden, der Wert auf kraftvollen Sound legt.
