Shipping speakers internationaly

Hello everyone,

Any idea on shipping a pair of speakers (around 30kg each) from usa to south east asia,
taking account that the value of the speakers is between 500 and 800 usd,
so any solution that doesn't multiply the price by 3 or 4 therefore making the idea maybe not a so good one ...
Thanks in advance for your advice and sharing experiences on the topic.
