I've got Creative Inspire T10s - just a 2.0 system but plenty loud for most uses, with good bass. Not sure if it's still sold but it used to go for PhP2,000. I know there's a successor to this system, sold in Singapore...I think it was the T12.

The T10 and T12 are junior versions of Creative's premium Gigaworks line, the T20 and T40. When I was shopping around, I auditioned the T10 and T20. Both were good, but the cheaper T10 had a warmer sound that was easier on my ears.
