I own several sets of Monsoon's different PC speakers, and all are very good. Not a VMPS, but pretty good, just the same.
There are 3 main models to look for: the MM-1000s, MM-700s, & MM-702s, in chronological order. There was also a 4 panel surround set, the MM-2000s. Monsoon had other smaller or later 2.1 systems, but none sounded as good as these earlier versions.
Eminent Technology had a higher end set of 2.1 PC speakers as well. They were LFT-11s. These had mid/treble panels, mated to a 'sub' with dual 6.5" woofers. Much rarer than the Monsoons, and much more expensive, at about $650 retail, IIRC. No longer produced by Eminent.
