Just a warning that there is a white van scam on speakers going on in Singapore, they are all substandard quality and being sold from 1,800 to 3,000$
I picked a set up for 80$ from a retail outlet, though i didn't connect them to my amplifier....too risky got my 80$ back with no hassle and informed them that they are substandard speakers....its not illegal in Singapore, so be very careful! Imagine i paid 80$ and they are making profit They look nice until you inspect very close they do not meet any standards at all. You will find a full list of dodgy stuff on the link
