Slight snag, I guess the speaker will not be sending a full range signal to that driver, it will be high passed I would guess?
Where is the crossover?
I presume the DSP/Pre amp section sets the crossover points and then that signal is sent onto the amp?
So probably no where to grab a full range signal from?
Why do you need to grab the full range signal? The sub is not going to go as high as the bass driver of the speaker anyway.
It's the lower end I want.
I would expect the mid drive to be bandpassed from around 35hz to around 5khz, however, I want the sub to do 20-35hz, but I don't think that signal will be there.
