Just when reading another topic on raising speakers, it got me thinking. I am starting to do some festivals and thinking about getting my speakers up in the air. What sort of scaffolding do people use for raising speakers?
I'd ask first-what type of loudspeaker systems and/or lighting are you looking to elevate?
My gut reaction is more folks go to larger stands, genie lifts, and truss type lifts/construction nowadays. I can't remember the last time I saw anything besides a small "Baker" type scaffold or one level of regular scaffolding, where here in the USA a 5' wide frame is a common size. Heights of sections vary of course. Prefab planks of aluminum/wood are often 7' long, but others are available.
I'd check around your area locally to see what is being rented, certainly before making a purchase.
Best regards,
John
