    Don't hesitate for $100 or less

    Nice product. About as loud as my Advent 100W computer speaker with the tonal character of my Altec Lansing but better, louder bass than the Altec 5" woofer. It's actually got a 7" but sounds convincingly as good as 8". Does sound better with a smidge of EQ as it is a tad overly sensitive in the midrange/500hz as mentioned in a couple of online reviews. I'm scooping out a couple of db (2) at 500hz and 1000hz and one at 250hz. I'm also boosting 2db at 62hz and it can also use a bit of boost above 10,000hz. Two extra db at 16khz is fine. This modest setting helps it from just sounding loud and bassy. I actually can notice the difference between a 128kbps MP3 and the higher bitrate/quality recordings which I could never hear on computer speakers before. I suppose this makes it worth a bit ...

    Left speaker distortion

    You are taking a big risk buying this. As stated elsewhere on the internet, there is a design and/or assembly flaw in the left speaker. 2 leads go to the driver. Either one ( or both ) of these leads is too close to the spider portion of the speaker and causes sound distortion. Or the spider itself is a bad design. I deflected to leads away from the spider as much as I could, but distortion still exists at certain frequencies! Like I said, bad design or bad assembly. I would never recommend this system!

    nice sound with cord issues

    First, the sound is way above average and volume gets louder than most. The subwoofer if far above average but if bass response is turned past 1/2 they tend to "rumble" in musical selections It becomes evident when a range of bass notes are played. However when it comes to nuances, especially in music, the Logitech Z623 underperforms resulting in a rather cold sound reproduction on the high end. I feel I am being overly critical by comparing them to my home system and please realize that ALL 2.1 computer speakers will not reach the top of the charts. I listened to Klipsch Promedia 2.1,Audioengine 5+, Bose Companion 2 Series ,Antec Soundscience Rockus 3D 2.1, and Corsair SP2200. with Audioengine 5+ being the best but at $400 vs $110 I choose the second best Logitech. Klipsch,Bose, Antec, ...

    I only thought my Sub bumped B4

    This 2.1 system is absolutely great! Haven't installed a decibel reader to find out the system's "Absolute Peak", but that's going on my To-Do list for tomorrow! Keep making awesome speakers! ( Pssst , Logitech... I love the attention To detail you have shown by setting the frequency range from 20 - 20,000 kHz)

    Very good quality sound, albeit not as loud or good as Promedia 2.1

    As for clarity of sound, and even bass, I would defer to Promedia 2.1 (that I also have). However, the price is attractive. I would rate Promedia 2.1 a 9.5, and the logitech Z623 an 8.5. If it has Bluetooth (which the next version Z625 has), then it will garner a 9. Still a good set of speakers though.
