Mackie SRM-450
De Mackie SRM 450 is de ideale klankkast voor kleinere feesten (zowel
binnen als buiten). Laat je niet misleiden door de grootte en het gewicht van
deze speaker: hij speelt enorm zuiver en door de geďntegreerde technologie
geeft hij een perfecte basweergave, zelfs bij hoog volume. Niet voor niets
gebruiken wij deze pareltjes op al onze events !
Voor grotere feesten zijn deze perfect te combineren met onze subkasten:
Forget about what other small PA speakers sound like. Especially forget what so-called "powered" speakers sound like. The active SRM450 is that different.
It has tight, steel-fisted bass to below 55Hz and detailed, articulate treble out to 20,000Hz. Midrange is warm, natural, and free from ear-fatiguing harshness. The SRM450 has astonishingly wide dispersion that lets your whole audience hear clearly, whether they're in the front, back, or way out on the sides of the room.
And above all, the SRM450 cranks! Without a hint of distortion, it effortlessly achieves sound pressure levels that would melt conventional speakers into a pile of molten slag.
