What type of filter do receivers use to crossover speakers to subs
I am building some speakers and trying to model the woofers in WinISD, and I was wondering how to model the receiver crossover to the LFE channel. I have tried searching online but I cant find a definitive answer of what type of filter they use.
I have a Denon x4400h and plan on setting the speakers to small with a 40hz crossover. WinISD default filter is a second order butterworth with a Q of .707, so that is what I used in my preliminary modeling, but I wasn't sure how accurate this is. Can anyone confirm what type of filter Denon uses to cross over speakers to LFE channel?
