The DJ-booth needs two arms to attach it to the speaker. To hold up the two arms we used ball sockets. This make the DJ-booth able to flex side to side if lets say a dancer hits the DJ-booth. It also makes the DJ-booth to fold up.
Here we have just heard Festmaskinens first sound. We configured the DSP to cut of frequencies below 60Hz and above 2000Hz for the bass-speakerelements.
For the piezohorns we applied at cutof under 2000Hz.
