You gotta know that with all the tech changes us sticking with a single model for two years has significance. It was funny to hear the audio guys doing the reviews mumbling about how unlikely that level of perfomance from $60 system.
Sonically they are not in the league of the others mentioned but they have a satisfying sound for MP3 and Internet radio and a good impact for gaming on the bottom end.
I've seen them go for as low at $55 at large retailers.
I have a set on my AlPB 12", used them on my G4 Quicksilver, recommended them to a PC neighbor, my brother-in-law, my father, my best friend - they were all amazed by these speakers, dynamic range, cost, control, design etc. It's a 2.1 speaker set-up with a standard 3.5mm stereo plug. Logitech uses neodymium rare-earth magnets in all their drivers, and ported sub-woofers with fibre-board cabinets - only the satellites have any plastic, and their stands can be swivelled around for wall mounting.
Monsoon has discontinued their multimedia audio division (or so I am told) so anything you can find from them that is current should be marked down fairly nicely. For example, London Drugs has the Monsoon Planar Media 9 (2.1) set for 69.98 when it's regular retail price was around $170. Both the Granville & Georgia and West Broadway locations in vancouver have a pretty good supply of these speakers.
The MH-702s (actually, the entire MM/MH series) have not been manufactured in some time, to the best of my knowledge.
If you are looking for something that doesn;t use electrostatics, I'd reccomend the Logitech Z3 set which are not only stylish, but sound excellent.
I agree with Nick...If you could find a Monsoon system that would be great. I have a low-end Monsoon system ($99.00) and the sound is fantastic. Looks like PosterBoy is right, Monsoon's computer line doesn't exist anymore so, you may in fact be able to locate some old stock and get a deal. They're powerful speakers with thunderous bass and crisp clarity! I haven't used other types of speakers, but have been quite happy with the Monsoons.
