The workshop was held by a group of activists at RampArt squatted Social Centre in London, England, on 3rd June 2006. This rough hewn video is mainly about 'Pedals', a powerful trailer system used on many demos and on Critical Mass.
The short clip 'pedals' shows 'Pedals' in action. The Workshop video '12vpart1' opens with a new experimental sound system being tested before going on to discuss the design and construction of 'Pedals' itself and sound systems in general in the following clips.

Thanks a lot!!!
Just stopping by to reinforce those other two reviews--keep up the good work everyone involved in those very clever designs...
and yes if someone could take a lil time out to quickly post some details about the midrange horn speaker and the tops then that would give it a sort of constructive completion...but hey loads of info on there...thanks a lot!!!

GoOd gOoD GOOD...
very helpful and inspiring indeed this workshop so even better someone (Doug) took the camera out and recorded it for all the rest of us who didn't attend.
Very informative and entertaining at the same time.
I'd be very very appreciative if someone could volley me some info over about the compression driver/horn and the tweeters (watts,ohm, wiring)
as the footage ends when it comes to be explained.
Thanks a lot though for all what's there.
Big up pedals!!!!!!!

Efficiency,efficiency efficiency!
Efficient amps, efficient drivers, creative use of things!
I enjoyed this,from both a non staged/no acting viewpoint, and due to the extensive knowledge of the guy in blue shirt - Ive used the same winisd program.
Using a Paudio complete horn is one option for midrange,another is a conical horn with an 8" or similar. See
