I've had a few systems I was tinkering with last year but sold them all and bought a used Yamaha Pro series. I bought some New JBL post prod speaks that have exceptionally smooth response.I added someold but always space age looking Heil high frequency transformers on top of the JBL enclosures. The sound is good but the room has way too much reflectivity from hard surfaces resulting in a pretty bad case of shimmering from roughly 7K to 10K. A drumkit nightmare guaranteed
