4 out of 5 eggsGreat Sound, but BIG!

Pros: -Awesome bass

Cons: The sub is VERY large

Other Thoughts: I love the sound that this speaker set puts out! It took me a little adjusting to get it the way I like it, but that's more a function of my system rather than my speakers. I only have the bass turned about a quarter of the way up and I can feel the thumping in my chest!

My only issue with it is that the sub is so darn BIG! I have it under my desk and pretty much use it as a footrest at this point because it takes up so much space. Now, I have a ton of room under my desk, so its OK, but many other desks are more limited on space. Just something to keep in mind if you're looking to buy this set.

4 out of 5 eggsNice set of PC speakers

Pros: -Several years of ownership and stiff running strong.
-No complications
-Easy to install
-My neighbors love them (kidding)

Cons: Sub is pretty large for a set of PC speakers, not recommended if you have a small desk or little room available.

Other Thoughts: Quite a nice upgrade over built-in monitor or laptop speakers. You can actually hear things!

2 out of 5 eggsDoesn't Look Good

Pros: They were packaged well.

Cons: One of the 2 satellite speakers has a bad BUZZZZ when playing sounds. The speaker that has the volume and bass control on it is not working correctly. I registered the product and filled out a support claim on Logitech's website. That was on 1/20. I sent them the receipt , S/N and all the information they asked for. I am still waiting for some feedback from Logitech. If they don't get back to me soon, I will be shipping these back to newegg.

Other Thoughts: I feel like I should be more patient??..Maybe it takes a week for Logitech to decide what to do? It took me 3minutes to fill out the support claim? Maybe they are really busy trying to resolve a lot of customer issues?

5 out of 5 eggsAWESOME!

Pros: Going strong after 3-years

Great price when I bought them ($109.99)

Crisp clean sound. Probably the best 2.1 on the market (next to Klipsch Promedia 2.1)

Cons: Not enough punch is the mid-range section.

Other Thoughts: Great for movies and newer hip-hop bass heavy music.

If you like the old punch of 80s-90s rock music, then check out the Klipsch Promedia 2.1.

2 out of 5 eggs

Pros: will play loud if wanted

Cons: No mids at all. When you listen to a song all you hear is boomy bass that is not accurate and highs that are too bright. Instruments are hard to pick up and parts of a song I hear in my car vanish when playing on these.
The boomy bass I'm sure is because the sub-woofer is trying to play above the range a sub should be playing, to try and make up for no mid range speakers in the satellites.
Turning the sub all the way off I was surprised how poor the small speakers sounded by themselves, although they do look nice. I honestly think they spent more money on the appearance than the parts inside.
I spent a long time playing with an Equalizer and sound effects and got them to sound acceptable, but acceptable is not what I thought I was buying based on the reviews.

Other Thoughts: If you don't care about quality/full range and just want something to go boom and shake the floor this will do it.
I am kicking myself for not getting the Klipsch - ProMedia's instead of these. The ProMedias I have since heard at a friends house and they sound much better. The reviews for the Logitech's I think are inflated too high and I didn't go with my gut.

5 out of 5 eggsFills Any Room With Good Sound

Pros: - impressive sound quality
- tight, clean bass
- three audio inputs
- solid construction
- attractive but unobtrusive style
- headphone mode allows use of volume knob

Cons: - no mounting option
- not easily user-serviceable

Other Thoughts: For the price, the sound is fantastic. The impressive volume these can produce is more than adequate for any computer desk or small home theater setup, filling my modest apartment.

The sound is likely not to audiophile standards - Logitech computer speakers have always seemed to favor an attention-grabbing combination of deep, felt bass and crisp highs, which is great for in-store demos of the sort which sold me on this unit but not necessarily faithful from an engineer's perspective. But be honest here - if you're looking at this type of product, you are probably seeking that sort of music experience, along with intense gaming sound and podcast voices that you feel in your chest. There is very little noise present even at high volumes, so long as your setup is properly grounded. For this product category, the sound is among the best, and the value is certainly great.

I didn't know it at the time of purchase, but the Z623 has three audio inputs (1x RCA + 2x 3.5mm) with an integrated mixer, allowing them to be used simultaneously. This has come to be my favorite feature. At my desk, I have it connected to three computers simultaneously (Linux, Windows, and XBMC media center). This product makes it possible to get great sound out of everything at once, switching from a movie in XBMC, to music on Ubuntu, to games on Windows, all without moving any wires around.

My only complaint is that, unlike my last set of Logitech speakers, this model has no mount points for affixing the speakers to a wall. This is a disappointment for me, but I can't take any points off for it, as this is not something most shoppers would reasonably demand from this product category. It wasn't something I was looking for while shopping either.

5 out of 5 eggsYou don't need surround sound, You Need These.

Pros: The Sound.
---Plain and simple, it is amazing. If you're one of those guys who wants it crazy loud (bass and/or treble), these will do the job and everything will still sound crystal clear. If they don't do the job, you either need hearing aids or will be needing them soon.

I however, do not like my music very loud and too much bass gives me a headache (but I had to try it out a few times). I love these speakers for the great quality of sound they give. While I don't like the bass thumping at my brains, I do like the bass you can feel in your chest. As long as you don't have neighbors close-by or attached to the same building as you, this bass is great. It really adds dynamic to action movies (assuming the movie maker mixed it so that the bass that wrecks your head isn't also amplified).

Besides the Sound.
---Since this is a 2.1, a lot of people are likely to use it on a desk setup (as I do), and I really like the size of the speakers. Not too big that they get in the way, but big enough to do a great job.
---There is a volume control as well as a separate bass control. I really like this. If it is getting late, I can easily mix out the bass with a turn of the knob so that I don't disturb the neighbors. No software needed, just a quick easy solution.
---There are some reeeaally nice rubbery pads on the bottom of the desk speakers to stop them from sliding around. I say "reeeaally" nice b/c at first when I picked up the speaker after using it for a while and they were kinda dusty, and I thought, "oh great, these are going to be a pain to clean"... one stroke of a wet cloth later and there wasn't a single piece of dust remaining! Good as new!
---Personally I really like the style of these. They aren't obnoxious or distracting, but when you look at them you can tell they're high quality.

---These do have holes for inputting music via an iPod or other similar device as well as output for headphones. I liked the idea of that, as it seemed convenient, but I haven't used either. I just use my computer for the music, and you won't catch me using headphones and wasting the potential of these amazing speakers! *I did just think of something, literally just now -_- ... I'm not sure if it works, but the headphone slot would be useful to me if I could only just use it for a microphone jack to save me from going the distance to my tower. Depends if it is for both or just one though. Next time I'm using a mic I may have to try it if I remember. So put that in as a "con" if you wish, but it doesn't concern me, I simply thought I'd mention it.

Cons: Only a couple of very, very small "cons".

The speakers are pretty sturdy, however, the front-to-back could use a bit more stability. (No, they're not going to fall/tip over on you unless you throw something at them or yank the cord). Perhaps a wider bass would solve that.

After using these for a year the inside is a little dusty. They appear to be able to be taken apart via an Allen Wrench on the front, but I have not tried it since it isn't too bad and I wouldn't want anything bad to happen to them.

Other Thoughts: The "First from Asia" thing was not on these when I bought them a year ago. That logo always makes me wary of a product... Plus it is a lot more expensive. If that goes away and these come back to the price they've been for quite some time ($130-$140ish), then I would hands down recommend these speakers to anybody who was in the market for some new ones.

5 out of 5 eggsBass In Your Face

Pros: This system has epic bass, even with the bass knob in the middle. And these get very loud, very quickly. The THX certification is a warning in its own right. They know loudness, and this system has it.

Side input/output ports are super convenient for shortly-wired headphones like mine. I think they also have some kind of mechanism that prevents the undesirable "pop" that is usually caused by plugging/unplugging TRS connectors.

Dials/knobs feel resistive and reliable.

Way better than the silver Dell 2.1 speakers I had before.

Cons: The cable leading into the right hand speaker (with all the controls) is pretty short. If you use this on the computer desk, you'll probably be okay. Those wanting to use these for tall entertainment centers might not be able to center the sub.

The volume is very touchy on the low end. But this is hardly a con; how else can you fit so much volume on such a tiny dial?

Not recommended for apartments, or dorms. Unless you want either angry neighbors, or unused potential.

Other Thoughts: There can be some distortion and clipping at super high volumes, but overall the sound is crisp and deep.

These speakers lack in high treble I think. Some kind of equalizer will solve this though.
