I retire long time ago already but......
rm800 for Top Palace? How bout no?
From a simple search they are made by Amerion, which in my day is another branch of chap ayam. Unless they bought KEF in the last few years and are now the pinnacle of audio ecstacy, I believe we can still call them chap ayam.
Any ori Sony, Pioneer, JBL speaker will far exceed your stock speakers.
If you wish to spend rm800, go listen to the cheapest Morel Maximo, German Maestro or Focal before buying anything.
Spend a few trips to the car accessory shop just to listen. Dun buy the first thing you hear.
Sorry I'm so out of touch I dunno whats in the market anymore.
