@Hotep:
I have hard time recommending anything particular, because if your setup doesn't do what's needed, or you have an ugly room mode, or you have different perception, then things might not work out. Also as mentioned, part of the tightness DOES come from lack of bass.
I talk about it here and there, but never needed to make a thread about this. The combo of B&C speakers 21DS115 in a 125(net) liter box with port tuned to 28Hz worked very well for me. Great tight bass, and when cut above 40Hz and let to play into 120Hz, it worked really nice. But there is more to it. Not full story of the affairs.

For your application, outdoor use, I suggest some lightweight (1-1,2 cm panels) U+frame boxes, sort of a cube without the back panel. Choose a good speaker capable of 100-150 W power and now the amplifier: stereo module with class D amplifiers 30-200 W and the supply ranging from 20 to 60 V depending of the power chosen. Lithium batteries ... but...did you say mobile?
