We utilize a three speaker sound system that includes (2) Mackie SRM450 powered speakers with one db Technology 800 watt powered sub.
Our systems deliver punchy, low end bass with clean mids and vocals, even when driven to extremes. Most of the (big) DJ companies in the Twin Cities do not use a sub(s). It makes a difference, really. Why pay more, only to get less in true sound quality?
We have back-up speakers available if needed for every event.
