Loudest portable speakers (IPhone)?

Can someone tell me what the loudest and best sounding portable speakers currently are?
I'm looking to be able to play these outside for at least 20 people to hear. I did not want to go as much as spending as Bose and would like to keep it under $100. I've looked at Kinivo, x-mini, ihome, Bose, Jawbone, etc.

Batteries and chargeable would be great, but not a necessity. I just need to plug my iPhone in or go Bluetooth. Any suggestions from experience?

It depends on what you want. The Ion xxx Rocker family of units might do what you want and you can actually bring it home for under $100.
