Summary: If you can get your hands on these speakers, you will not be disappointed! The bass on these is incredible and there is no distortion on even the songs that are bass heavy. Highly recommend and I wish Altec Lansing would stop making inferior follow ups to these amazing speakers!
Summary: It took quite a while to get all the parts I needed to be able to connect it to the electronic keyboard that I bought it for, but now that I have them, the system works very well. The extra volume and depth of sound I'm able to get from my instrument is amazing. It should be pointed out that this particular item is NOT US COMPATIBLE and should come with a mains adaptor. Mine didn't so there was a considerable time delay before I could even try it out.
Summary: I had before a computer speaker system but it's only 2.0 (also from Altec Lansing) which I'm not satisfied of what I'm hearing even-though it sounds very very good but it misses something. And I step-up with this one (VS4121) and I had this one for a couple of weeks now and tuning it and I would say, "WOW THAT'S IT, THIS IS THE BEST period end of the story".
Summary: I am not a demanding audiophile. But adding this to my computer makes watching videos, YouTube and just plain music very enjoyable. I have the speakers next to my computer screen and the woofer is on the floor. I've had this unit for 6 months or so, and it's still working great. No problem. Easy to install. Extremely simple to use.
Summary: My great-uncle built his vacation home in 2007 and he had his VS4121's no later than 2008. These are by far the best desktop speakers I've ever heard. After hearing them for the first time, I was hooked. The highs are very detailed and have no distortion from what I've heard. The mids are phenominal, as they really do fill the space they occupy quite well, whether turned up or at a low comfortable volume. The bass is breathtaking.
