Upgraded from the Z4 and very happy
I couldn't find any reviews from Logitech Z4 owners, so I decided to take a leap and tell you all about it. First off for those of you who don't know, the Logitech Z4 2.1 system was the "mid-grade" and right under the infamous Z-2300. The Z4 remains one of the best mid-grade speaker systems ever made by Logitech. I've owned and liked the Z4 for the past 3 years but I wanted something more... I wanted more mids, more highs and of course, more bass. I was going to go the Z-2300 route and buy them used (since they are out of production as of this review). However, I wanted a system with a warranty, so I decided to pick the Z623. I never listened to the Z-2300, so I can't comment how they compare.Looks:At first glance, the Z623 feels like a more expensive system. Looks wise, they are ugly. The Z4's look more elegant. The Z623 speakers have that upside down raindrop look to them. What were Logitech thinking with this design?? The satellites took up a lot more space width and depth wise, but thats ok since the bigger drivers on the Z623 delivered more rich sound. The satellites felt expensive and did not feel cheap at all. They are made of plastic, but the hard expensive plastic feel. I also like how the satellite speakers have a metal grill protecting the drivers. On the Z4, nothing is protecting them. So the risk of damage is a lot higher. I was always paranoid around the Z4 satellite speakers for that reason. Now with the Z623, those anxieties are gone.Overall Sound:Regardless of looks, the most important part is the sound. Since the Z4's already produced great sound quality, it would take a lot to impress me, and luckily these did! First the bass hits hard and low. At the same volume level, the Z623 packed more bass. If you love bass, and need bass, this is the system for you. The bass is accurate and more boomy then the Z4's. Keep in mind the sub-woofer speaker is much bigger then the Z4's. The Z4's lacked mids and I heard the Z623 lacked mids as well. Comparatively speaking, the Z623 delivered more mids then the Z4 and I was quite relieved. I play games and listen to music and was able to hear small details I didn't hear with my Z4 and now I hear them with the Z623 because the Z623 has improved mids over the Z4 (as it should for being almost 2X more expensive...) One of the important things I look for in speakers is the highs. I want to be able to hear the bullet shells drop on the ground in Battlefield 3 and Modern Warfare 3. I want to be able to hear the trees ruffling in Skyrim. I read a couple of reviews that said the Z623 lacked highs. I disagree. The Z623 does highs wonderfully, and I think if it was any brighter, I would have to tone them down in the EQ on my PC. Even though the Z623 does not have a separate tweeter, the Z623 delivered more highs then the Z4. It was more bright and it met my expectations for highs. FYI: Some people thing where the THX symbol is on the speaker are tweeters, but they are not. They are ports, not tweeters. Like I said, even though the speakers lack tweeters, the drivers were still able to produce very bright highs (more then the Z4). Overall, the sound on the Z623 are much better. The Z623 sound more full and rich. What I mean by this is, I was able to hear small details in the mid and highs that I didn't hear with the Z4.Also note, after about a couple days of usage, the sound started to get better. The mids and lows (sub woofer) started to sound better. Keep in mind like most speakers, it takes some time and use to loosen the coils. After about 4 days, the speakers sounded awesome. I was a bit nervous at first because the speakers didn't sound full.Sound with music:I listen to everything from techno to rap and everything in between. Music was accurate and anything with bass you could feel it. Listening to music on the Z623 breathed new life into all of my music. The Z4's played them well, but the Z623 sound range just made everything sounded more alive and in front of you, if that makes any sense.Sound with gaming:I do a lot of gaming, so sound is just as important as graphics to me. If the sound is not good, the game play suffers because if you can't hear the foot steps behind you, or a dragon coming to get you. With the Z4, the sound was great, but with the Z623, the sound is even better! When I was playing BF3, I heard more detail in the explosions. Even when reloading my weapon, I heard extra "clicking" sounds of the gun that I did not hear with the Z4. In Starcraft 2, I was able to hear more detail with the workers were mining for minerals. When playing Skyrim, the sound of the dragon fire coming towards you comes with intensity and depth that the Z4 couldn't deliver due to lack of mids. Even though the details are small, that make a huge difference because it just enhances the experience and the detail.Usability:At first, I was sad to see Logitech took the cheap route and not offer a separate pod to control the volume. I really liked how the pod worked on the Z4. However, I am now glad they didn't for the Z623. No pod means less wires and more space on your desk. On the right speakers is where you will find the power button, volume control nob and bass nob. When its on, a small faint orange LED light is right above the power button. Its very dim, so it doesn't distract. The volume nob is smooth and doesn't make any "crackling" sounds then you adjust the volume. The bass nob feels smooth also. Over all, the control scheme for the Z623 is better then the Z4. I sometimes like to hear songs from my iPod through the speakers and was glad to see the Z623 does have in audio input. This is something that the Z-2300 doesn't have.Summary:Pros- Sound quality is great, a good improvement over my old Z4's.- Bass is accurate and can definitely shake your room. At high volume, everything on my desk almost fell over!- Mids were still lacking, but from the Z4, the mids were better.- Highs were nice and bright. It sounded as if the speakers had tweeters (but they do not).- Integrated controls on the right speaker saves space for a separate control pod.- Sound is rich and full.- Video game sounds brought out the games. It sounds so clear and crisp that you felt as if you were in the game.- Metal grill on the satellite (and sub-woofer) protect the speakers very well.Cons- Mids are still lacking, but not as bad as my old Z4's. But the lack of mids aren't bad, just wish it had a little bit more mids.- Speakers looks ugly.- Satellite speakers take up much more space then the Z4.- Retail price is high, but if you can snag them for $120 or under, do it.Final thoughts:For those of you who are clinging to the Z4 but are itching for a better upgrade, I would highly recommend the Z623. The Z623 sound quality is just like the Z4, but better. Its better because it packs more bass, better mids and higher highs. Z4 owners are penalized price wise because theirs nothing in the $60-$80 range that can match the sound quality of the Z4. If you want to maintain that sound quality, you have to get the Z623 to be satisfied. I listened to the Z4 replacement, the Z523, but it was not as good as the Z4. If you have the money to upgrade, or if you want to get something that will be better, then don't wait, order the Z623.

Bang for Buck...
I had speakers built into my monitor but they were soft when playing films; and just okay for playing music.So I spent a bunch of hours trying to figure out the best value for pc speakers. I had Logitech some years ago, a very inexpensive set with a small bass and they worked brilliantly back then.These speakers work even better. The price is higher than back then but the quality is superior. I wanted an easy access power button. Another brand remained powered at all times so I rejected that option. I like the volume and bass control as well.Films now have the sound they deserve and the music is ideal. There is plenty of reason to play louder as well but I find I keep the volume at about 5o% on the speaker and 3o-4o% on the pc. I set the bass at 75%.I chose analog as I do not have an optical connection on my pc. Set-up is easy.I hope this review saves you some time in your search for pc speakers. I purposefully was concise and I think you will be pleased with this purchase.

Fantastic!
With the weather warming up, it was time to move my stereo system from the basement back out to the garage. This required me to use an old sound bar to stream my music for my basement workouts. That just wasn't cutting it. I picked this product up and I couldn't be happier. I think the sound is just great and has no problem filling my basement with music to help power me through my workout. In fact, I can't turn it up much more than half way as it would be too loud. Easy setup - just plug in and play. Been awhile since I've been this pleased with a product from Amazon!

Good quality sound in a small package
I have used Logitech sound systems for quite some time and this does not disappoint. For the price I paid it was quite worthwhile. Has a crisp audio quality and good bass. I expect it to serve me well for quite some time.

Great speakers with most of the features I wanted... but they could use a treble control
I recently starting having trouble with the speaker system I had been using for about 4 years. After those 4 years, I wanted to get a system that had a separate power button and volume control rather than a single knob for both as my last system had. I like being able to turn my speakers on and already have the volume adjusted to the level I use most.That is one of the biggest "PROS" about this system for me. A stand-alone power button and a stand-alone volume control. I also like that they are on one of the satellite speakers rather than on a wired control "puck" like some other Logitech speaker systems. Not that there is anything wrong with a system that has that particular setup, I just wanted to limit the number of cables and wires running around my desk.I set these speakers up shortly after they arrived this afternoon. The sound is excellent though a bit heavy on the bass end of things when the bass control is in the default center position. I should add that the center position for the bass is better for music than for videos with dialogue. Turning the bass level down can help clear the "muddiness" that results when watching video. However, the better solution would be for Logitech to have included a treble control in the design of this system. After all, sometimes you want to boost the treble without cutting the bass. Not to mention that when a system has controls for both bass and treble you would tend to expect a better balance between the two when the controls are both set to the default.I know some folks have mentioned a "hum" or "buzz" with this system. I was worried that I might have this problem when getting things in place but, once I made sure there was no tension on the speaker connections that went away (I don't think this is the same problem others have mentioned but it seemed to be the same "hum" as a result).A big difference with this system compared to the previous two speaker systems I have had is that both speakers plug into the subwoofer as opposed to one connecting to the sub and the other plugging into the first speaker.One of the video reviews makes mention of the right speaker connecting to the subwoofer using a VGA-like connector making it proprietary and not easy to replace or use an extension cable should you want more length. First of all, these various connectors tend to always be proprietary even when they are the same "type" of connection. My previous two speaker systems both used a 9-pin DIN connector but each was a different size and the pin-out was different with each system so that, even if both connectors were the same size you could not used the satellite speakers of one system with the other. So, I have absolutely no problem with the VGA-style connection. That video review also states that while the connector "LOOKS" like a VGA you cannot use a VGA extension cable should you want/need more length. I have no idea if this is true or not. I have not tried it. I will say that just because a Logitech employee says you cannot use a VGA extension does not mean it is true. The only reasons it could not work is if the size and/or shape of the connection is slightly different from a standard VGA connection OR if some of the pins in a VGA extension don't go to the right connections within this circuit. Otherwise, I see no logical reason why you could not use a VGA extension (though I COULD be wrong).I went with the Z623 analog version of this system rather than paying more for the Z625 with optical connections. As such, I cannot say anything in regards to connecting via an optical port. Aside from the connections and any digital to analog converter the 623 and 625 would seem to be identical as far as the volume and bass controls and the speakers themselves.Again, this is a VERY nice speaker system. The only real "CON" for me is the lack of a treble control. Yes, I could make adjustments using the EQ controls within my computer but it would be much simpler if the speaker system had a treble control built in. This is the only reason I am giving 4 rather than 5 stars. If Logitech had put a treble control in this system I would likely give it a full 5 stars.I would like to say one more thing if you buy either the Z623 or Z625 because of the THX logo expecting to have sound like in a movie theater you "MIGHT" be disappointed (extreme emphasis on "MIGHT"). Overall these sound very good but, I am sure you could get similar sound quality from a system that does not have the THX logo whether it be a system from Logitech or another company.
