Review: Blown away by quality - Only set these up today of writing, and had to write the review. Admittedly I had also just upgraded my sound card from a Creative Omni external to the awesome Creative ZxR PCIe. I was using the (again Creative) Kratos 2.1 PC speakers, but I wanted something with a little more punch to compliment the new card. I originally paid £60.00 for the Kratos S3s and to be honest they were pretty good for the money. I've had Logitech speakers previously and was never really that impressed, but these Z623s were just off the scale for the £75 paid. I was a bit concerned initially. Reviews seemed OK, and having the THX standard I was just a bit worried they would fall short for a sub £100 set of 2.1 speakers. Thankfully though, my concerns were short lived. Firstly: just unpacking them you could see and feel they were of good quality. The two satellite speakers, despite being compact, were heavy and felt sturdy. The solid volume control, bass, and power button, along with the THX logo give the speakers a real rugged look. The sub-woofer was surprisingly bigger than I thought and it really packs a punch and was also of a solid build quality. I ran a couple of THX test videos from YouTube, and the bass from this set up just knocked me over. I watched a Netflix film, played plenty of music through them, as well as ran my PS4 (Via PC optical Line-in) through them and really couldn't find much to disappoint. I'm happy to give this 5 stars across the board. For £75, they're worth every penny. I will also add that I was using these in a small environment. I dont yet know how they would fair in a large room, but for a PC speaker set up, they are just awesome.
Review: Whew, what terrific speakers! - These speakers are terrifyingly amazing! The quality of sound and the punch they pack, all within a moderately-sized package, is astounding. As other reviewers have pointed out, these are excruciatingly-LOUD, distortion-free speakers. 200 watts RMS is a LOT of power! Make sure the roof of your home is anchored firmly! Frequency response is fabulous, and tests in my own house with pure sine waves show these can descend to 30Hz, assuming you move around the room to find the various "sweet spots", sometimes necessary with low frequencies in smaller rooms such as mine. 20Hz is really pushing it, but I believe the THX specifications claim speaker systems bearing their logo can go down to 20Hz at -6dB, so the fall-off at such a low frequency is to be expected - but we are talking here about notes that would normally be generated only by church or cathedral organs - or synthesisers. Last night, I played, at high volume level, the earth-shattering Toccata from the "Suite Gothique" by Leon Boellmann, as performed by Daniel Chorzempa somewhere in the USA on what must be a giant pipe organ. The Logitech speakers almost blasted me from my seat! If you've never heard this track, then buy the CD, "High Tech Organ" (Philips 4266812), if only as a test piece - you won't regret it. When selecting these Logitech Z623 speakers, it was a choice between them and the Creative Gigaworks T3s, but I opted for the slightly more powerful Logitechs, and am sure I made a good choice. One good advantage the Logitechs have over the Creatives is the positioning of the bass control on the front, right-hand satellite speaker - whereas the Creatives' bass control is on the rear of the subwoofer, in a difficult place to access. I had originally thought people complaining about the Creatives' bass control placement were making a lot out of nothing, but now I really do understand the advantage of having the control right in front of you. Some recordings need the bass turning down a bit, others need it increasing, according to personal taste. For my own part, on the Logitechs, I've found having the bass control only about one-third of the way up is more than sufficient for most music. I recommend these good-looking, high-performance speakers wholeheartedly, without reservation. They are made (as in the case of the Creatives) by a company whose name can be trusted. Don't hesitate, go and buy!

## Questions & Answers

**Q: Hi are those speakers have 200 watts ? Because on technical details says 35.**
A: Website states 200 Wrms total (130 Wrms subwoofer, 35 Wrms each satellite), 400W Peak Power. 
Freq. response 35Hz-20kHz, Input Impedance 4ohms (20Hz-20kHz), Sound Pressure Level (SPL Max) > 103 dBC

**Q: Can you mount these speakers on wall and how?**
A: The shape and size of the large Sub-woofer precludes it from being wall mountable. The sub-woofer also benefits from using the floor as a medium to transport deep bass rumbling sounds. You could mount the two smaller speakers on the wall with some shallow shelves or small brackets. The connecting speaker cables are not overly long either so you would have to splice them to get any distance between them. I hope this helps.

**Q: What's the adapter type? i'm guessing they require uk sockets. i'm from south africa and we use only the eu type.**
A: It is a standard 2 pin figure 8 IEC power lead so you can connect to any 220-240V supply with any spare lead you have

**Q: How can we contact direct in regards to warranty**
A: Probably best to contact Logitech directly with your receipt handy

### ⭐⭐⭐⭐⭐ Great For Music , Films & Games
*by D***T on 20 May 2012*

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.....
