I have a powered monitor 5.1 speaker setup. The mains are not full range so I need to do bass management. I've been listening to my 5.1 albums with a DAW like everyone else. There's now a surround capible media player (XBMC) but it doesn't have a bass management feature. This would be great to use. I could store my surround albums as 5.1 flac. So... is there some way to do basic mixing/aux send/crossover eq/build a bass management system with OSX tools?
