Summary: I had this speaker for sometime and it performed well. With the volume up considerably the sound quality begins to fade. after a year the speaker with volume control (right) started to fade in and out. then it stopped altogether. Disappointing but I promptly bought another logitech speaker system. Logitech=quality.
Summary: I got these speakers refurbished off of ebay for $24.95 with free shipping. I am very impressed with these speakers. I am running the frequency at 50 and it is working great. The highs are as good as the lows with minimal distortion when played at highest levels. Overall it is a great investment. The only con is that the sub volume is on the back of the sub so it is difficult to reach.
Summary: I picked these up for about $20, and they're very much worth that (and maybe a bit more). The bass is nice and deep, but the mids are thin and the highs could be a bit clearer. If you're broke and are using these for gaming or MP3's, they'd be pretty good so long as you're not too picky with sound. They cost a bit more, but the Logitech Z-3 series gets much fuller sound.
Summary: We are a frugal bunch and when I saw these speakers on the clearance rack for under $30, I grabbed them and it turns out the actual price was under $20! We needed some decent speakers for our recently purchased used Apple G4, and so I thought these might help bridge the time till be could afford something good. Well, we won't be parting with our Logitech X-220s anytime soon. I was quite surprised by the clarity and depth the two small speakers provide.
Summary: I don't know about some of the reviewers in here.. but why buy a subwoofer powered system if you're scared of a little bass? Yeesh.. Despite what the faint of heart say the bass is not _that_ overpowering and compliments the satellites quite nicely. This is one of the best deals ive had with average consumer audio equipment. How can you go wrong for 30$?
Summary: I bought this based on reviews. The first one came dead on arrival. Amazon took it back no problem. I have the second one now and the left speaker goes in and out. I'm too lazy to send it back. Besides, I threw away the original packaging.
