Lots of 41Hz based Boomboxes at the Roskilde Festival

There will be at least a dozen 41Hz amp based Boomboxes at the Roskilde festival.

The Roskilde festival is one of Europe's largest rock and music festivals with 120 bands and 75.000 daily visitors. This year it starts warm-up on the 27:th of june and the actual festival is 1-4th of july.

Oh, maybe 'Prince' will come to Roskilde Festival 2010 !


Thanks to a very high efficiency, the 41Hz switch mode amplifiers are very suitable for portable players for a festival, where a player should run for days on battery power at high volume.

Another reason some of these amps work well is that they are designed for single rail power supply and have bridged outputs. This basically means you can power them from a single battery and get a high output power with a moderate supply voltage. The most commonly used boombox amps are AMP6-BASIC and AMP9-BASIC.

Here are some tips and links about festival Boom-boxes from the Roskilde festival forum:

There is a 60 page thread on the DIYAudio web site about the Boominator project which is powered by two AMP6-BASIC. The Boominator - another stab at the ultimate party machine

Or right here under Customer Projects too, of course! HERE

The AMP9x is popular too: Our member Kain may have his box ready too. Can he out-class the Boominator?

Here is a AMP6-Basic based Luxury boombox model:

This will do too:
And some will build or finish them at the site!
All fun !
