I'll shortly be looking for small speakers for monitoring on location and in less than ideal places.
In such scenarios (in fact, in almost all scenarios) I do most of my work on my AKG K712 headphones, but there is always the need for decent playback speakers for the clients, and sometimes I have to some editing/mixing where others wish to hear what's going on.
I did a project in a shipping container a couple of months ago. I didn't want to haul my main ae22 monitors from my studio, so borrowed a pair of Alesis M1 520 (my old pair, as it happens), and they were OK for playback etc, but I'm looking for something a bit better. I don't wan't anything too big, as pumping a lot of bass into such environments wouldn't be too wise.
I don't feel it would be worth (nor possible, really) stretching the budget to the Neumann KH120 (it would also give my current monitors a run for their money in my own studio, creating more headaches!) The perfect option, I think, would be a pair of Acoustic Energy ProSats, as they would be consistent with what I already use in my studio (ae22). They'e discontinued, however, and haven't seen any used ones. Next on my list are the Equator D5 - I owned a pair before and liked them, and the price is right.
That's about the top end of the budget - is there anything else I should keep an eye for? There is no real urgency here - perhaps I should just wait until I see an used pair of ProSats?
Other approach would be something really cheap like the M-Audio AV40, which may well do the job for playback.
EDIT: The small Eve SC203 recently reviewed look tempting, though I'd really like 5" drivers just so they look more serious (if I was working alone I couldn't care less!). The master/slave format seems ideal for these scenarios too, as the less mains sockets needed the better!
The iLoud microMonitors come to mind. Doesnt get more portable than that, and they pack a punch.
