[microsound] [advice] Portable, battery powered speakers for outdoor microsound

It does seem like your requirements are modest, but  you haven't  
mentioned what kind of area you need to cover (at what levels),  
resources etc.

In any case, as an "alternative" to portable battery powered speakers,  
a half-decent car stereo system can pump out a fair bit of sound  
provided the power and speaker cable runs aren't too long, and one  
well charged car battery (high capacity deep cycle is better) should  
provide more than enough power to run a modest (but better than just  
about any other off the shelf portable battery powered) speaker system  
over an evening. You'll also still probably need to provide  
alternative speakers (or enclosures) to the ones inside the car for  
the concert but that shouldn't be too hard to sort. If the car can't  
be in the area, you could just haul the relevant bits to the site: 12v  
(ie car type)  batteriy powering (one, or more if needed) car stereos  
(cheaply obtained at a local wrecker or second hand dealer) could be a  
good solution, given you are planning to broadcast via low power FM  

Alternately or possibly as an adjunct  if you can get a vehicle (or a  
decent capacity battery) in the vicinity get an inverter that  
generates enough power to run your Alesis speakers or more...
