[QUOTE="Per Søvik, post: 73674, member: 1285"] Re: HPF and LPF Crossover Curves Typically, the electronic x-over or more recently the speaker-processor serves with two different purposes. One of the purposes is to provide the processing for a two- or three-way speaker using bi- or tri-amping. The other purpose is to provide the processing and functions for subwoofers. Allthough both purposes are often served by large a single large processor in bigger systems, many of us live in a world where we are adding subs to a system that is already processed, be it passive, active or powered. While it is perfectly feasible to construct a full processing set up for an active system, the pitfalls and limitations have been repeatedly shouted from the rooftops, and I'm not going to get into that anymore. The sub-application, while some seem to be unable to see the distinction, is a different animal alltogether, allthough the principles remain the same. Once you start adding subs to a system, you are often in a situation where the processing isn't readily available, some powered subs send the whole unfiltered signal on to the tops, most powered tops lack a variable low cut, etc, so even the standard manufactured-approved and presumably safe setup can be greately improved by eploying some processing inside the desk. As the number of subs increase, new possibilities open up, and lacking an expensive processor to do the job, the X32 now lends itself well to implement cardio-subs, endfire arrays and what have you. I can now basically take my eight channels of sub amps and do whatever I want with them, I have the outputs, the routing and the processing, all in a desk that cost less than some of the dedicated processors out there. In a sub application, there are so many ways to add safety for the mains, from ensuring the mains go silent if and when the desk resets, to putting the subs on aux sends ensuring the bass heavy sources never get into the mains in a big way in the first place.
