I've been using powered PA speakers for awhile and love it although I didn't have the best of luck with the mackie 1521z cabinets. I've got a pair of those, and a QSC 18" powered Sub. I love the QSC. It gives me low end for days, But I need better mids/highs. Are the IP cabinets worth paying over $2000. If I get one yes reply that's all I need to order one. Thanks brian
