I had to replace my old Altec Lansing acs45 because the cable/plug broke and [I thought] wasn't worth repairing. The acs45 was such a great 2.1 system, so I thought I'll stick with AltecLansing and ordered the vs2521.
I use a speaker system only to listen to music, no gaming etc..
What I liked: plenty of power, bright high tones, kind of stylish.
What I didn't like: overwhelming sub woofer (hard to adjust to reasonable levels), very poor mid-tones, awkward wiring and on/off switch.
NOTE: the acs45 10-year old speakers were MUCH better than these! Ironic. Couldn't Altec just use the same circuitry in a new shell?
I returned these speakers mainly because of the poor midtone range.
I guess I'll have to spend about twice as much or even more if I want better music playback quality.
