Just keep on ticking & sound great

I was tired of taking our mackies in to be repaired so we purchased a RMX2450 to see how it would hold up for our church. After one year we purchased another and, Lord willing will purchase two more by the end of the year. Great amp.

Can't go wrong with QSC!

I've got an amp rack full of these things, and they are easily described as pure power. I use a 2450 to power my dual 15" sub cabinets, and they sound fantastic. The price is more than right, and you'll be wow'd too! Contact your Sweetwater rep to grab one (or two)!
