I checked a few days ago,its RM500.If I remember correctly when I bought it I paid RM515 for it.

I haven't personally listened to the promedia 2.1 but from what I have heard from people,apparently its better than the one from GMX series.I won't be surprised if its true,too bad it is discontinued...

Its definitely not perfect by any means,even for its price range.It sounds pretty clear and the bass is real punchy,though it may not be suitable for certain kind of music.Just be aware that the speakers can be very bright sometimes and don't turn up the subwoofer a lot or the bass will sound bloated (especially for music).
Still its a really powerful set of speakers and sub,you can tear the house down with these
