Summary: I have had Altec Lansing before, but this isn't as good as the last one I had. It quite frankly was weak and didn't have the sound that I wanted to have while sitting at my computer listening to music. I ended up giving it to my son going to college and will be looking for something better.
Summary: Quality from these speakers are not extraordinary but serves it's purpose. I have these plugged into my HD to to add some bass to my movies. Mounts very easily, just by a nail or screw ( I've attached pics ). People complain about feedback and humming but though the feedback is present, I only experience it when my cellphone is with a 3feet or so range from the controller or speakers.
Summary: Very good sound for the price and size. I went to a store and did a side-by-side sound check of this system vs. the similarly priced Logitech x-230 (both have good sound for under $40). While both were decent, the Altec Lansing VS2421 was slightly more crisp and true, but the sound diff between the two is not huge and the Logitech is slightly louder at 32 Watts vs. 28 Watts RMS.
Summary: Hola muy buenas amigos, pues una noche más me siento ante mi PC a escribir sobre este sistema de altavoces para el PC que tengo desde hace un par de años. PRESENTACION: Bueno si la memoria no me falla mucho creo recordar que venían en una caja de cartón serigrafiada de unos 40x30x30 en ella podemos ver distintas imágenes del equipo y encontrar fácilmente las especificaciones que nos facilita el fabricante.
