De Mackie SRM 450 is al jaren een standaard in de geluidswereld. Hij is multi-inzetbaar voor Dj's, bands en recepties dankzij zijn prestaties en prijs/kwaliteit verhouding.
Door zijn schuine zijde is hij ook perfect inzetbaar als floormonitor.

Wij hebben verschillende sets in de verhuur steken in handige transporthoezen, zodat gebruiksporen tot het minimum worden herleid.
