Having experimented with a few devices in our venue, the Stairville AF150 has definitely emerged as my favourite.
Our room is around 180 capacity, running both live shows and clubs. This machine is more than adaptable enough in terms of spread and power to cater for the creepiest Black Metal band right on to the cheesiest clubnight.
The timer and volume dials on the remote could perhaps do with numbers/increments so you can note down your settings, but once you get used to them they are extremely functional and convenient.
All in all, would definitely recommend as a simple, reliable solution for any small venue or club room.
