    As always, I'm completely thrilled with Logitech and its products, they never disappoint. For a mid-tier speaker system, this setup is fantastic. Excellent bass/mids/highs. Love the bass control knob and headset hook in on the control speaker.

    Vine Customer Review of Free Product ( What's this? )
    I listened to the Harmon Kardon Soundsticks for years and was happy with the crisp, clean sound and good bass. However, it lacked midrange and didn't have much of a soundstage. A few weeks ago, I upgraded to Axiom Audiobytes which blew my Soundsticks away with a rich sound and expansive soundstage. I've received the Logitech's to review and have done a direct A-B-C comparison of all three 2.1 systems.

    Overall, the Logitech's stack up very well with the Audiobytes which cost significantly more at $530. The Logitech soundstage is very good, but not ridiculously expansive like the Audiobytes. The Logitech's musical quality is excellent although slightly harsher than the silky smooth Audiobytes. Voice clarity is great on both systems. Both do a good job with high, mid, and low range frequencies. The subwoofers are similar in that they complement rather than shake the walls. Even though the Audiobytes sound better, any differences between the 2 systems are subtle, and I wouldn't lose much switching to the Logitech's. In short, I am extremely impressed with the Logitech's and would be happy using them permanently.

    Direct comparison to the Soundsticks reveals Logitech as clearly superior. The Soundsticks simply sound small compared to the Logitech's. The strength of the Soundsticks is high-end clarity and this is matched by the Logitech's. Frequency balance is significantly better with the Logitech's because the Soundsticks lack midrange. The Soundsticks' sub is a little more boomy than the Logitech but both work well. Since both speaker sets cost the same, the Logitech's are the obvious choice.

    The build quality of the Logitech's is very good. The satellites are solidly constructed with nice heft. Control knobs are big and easy to use.

    I mainly got this set for music and some games. After the terrible disappointment with the Logitech Z506, I decided to try my chances on this set. I was afraid the bass is too overpowering for music but it turned out perfect.

    + Bass is truly clean and powerful
    + Great highs and mids as well
    + No buzzing, humming, crackling noises
    + On-speaker bass and volume controls w/ aux and headphones

    - Speaker wires alittle short. Maybe 2 feet more would of been nice.
    - More expensive than the z-2300

    Overall for music lovers and gamers, this set is a great investment.

    Vine Customer Review of Free Product ( What's this? )
    I love listening to music and watching movies on my computer, but I have always relied on relatively cheap speakers (or even my built-in laptop speakers) to provide my sound. I decided to order these speakers and take my music and videos to "the next level" and see if these speakers could deliver the loud, clear, and rich sound I expect from more expensive stereo systems and speakers.

    Below are my positive and negative evaluations of the Logitech Z623 speaker system.


    - The subwoofer is huge, and provides a nice, rich, bass sound. I am amazed at the loudness and clarity of the bass.

    - The speakers may seem little, but they produce a big and rich sound, with very little vibration or feedback.

    - The overall sound quality and clarity is impressive. When I listened to my favorite songs, I heard sounds and instruments I had never heard before. Watching videos with these speakers has opened up an entirely new (and great) listening experience!

    - To test the unit's power, I turned the volume on full blast (with the computer volume turned on full as well) and the sound was pretty much flawless. I didn't hear any rattling or feedback. These speakers are pretty loud, and definitely loud enough for what I need.


    - The cords are a little short, but not too short as to be annoying.

    - The unit is large (the entire set weighs about 22 lbs). This means that moving the speakers and subwoofer is a little inconvenient. I am used to moving speakers around with my laptop. I really can't do this with these speakers.

    Overall, this is a great speaker system, and I am glad I upgraded from the cheap speakers. Until now, I didn't know what I was missing using cheaper speakers.

    Vine Customer Review of Free Product ( What's this? )
    So I've spent the past three days attempting to find something that I don't like about these speakers. I've played every kind of music that I own (including spoken-word stuff), I've streamed video, I've streamed audio, I've checked nearly every single thing that I can consider. And yet, I'm still at the same place I was when I received them--they're the best computer speakers I've ever owned.

    1. Excellent controls: the big, easy-to-use knobs that regulate both the volume and the bass intensity are easy to use and very precise.
    2. THX: the sound is very well-rounded, with crisp highs and lows that SOUND and don't just boom.
    3. Responsive: when I've owned other computer speakers, there always seemed to be a delay from the main speakers to the subwoofer. No such problem here. The sound is very precise and clear regardless of music type.
    4. Small blueprint: for the volume and amount of sound that you get from these, they don't take up much space at all.

    1. One of the desktop speakers put out a bit of hot air from around the control knobs...it's not that big of a deal, but it is noticeable.
    2. The subwoofer is the primary speaker for most ports, which means that you can't really place it flat against a wall. And one of the speaker cords is a bit thick, so I can see how cord-invisible installation might be an issue.

    And that's it. If you think the cons are minor, you're right. I'm not sure that I'd race out and replace one of my home theater systems with these if only because they're 2.1. But if you have a small space or don't really want a full-scale system, you'll probably love these even for televisions. For computers, however, they're fantastic. Highly recommended.
