I need help setting the crossover of my Sub (REL T9X) with my Klispch R8000F (MK1). I use a Cambridge Audio CXA81 as a reciever. So I don't have any kind of bass management or room correction available. The REL is connected via the High Level Input. A few weeks ago, I borrowed a Umik1 just to see the response of my Klipsch and here is the graph (avarage of 3 takes). The graph is without the subwoofer... only the Klispchs. [/url][/IMG] REW — Postimages I'm a absolute noob when it comes to audio. So, acording to the graph, where should I set the crossover at? 30? 40? Somewhere else? I know that any advice to this will be purely theoretical and I will finetune with my hear but it would be great to have some guidance. Thanks!
