Not sure I understand your question. But the Bass is kept out of the Oris Horn.... The full signal from the pre-amp still 'goes into' the 45 Amplifer, as well as the Hypex Amplifer.http://www.bd-design.nl/contents/en-us/d71.html
I did try a Marchand Active Crossover once, that would filter out the Bass before it reached the Amp, but it was a Mass of extra cables and added more hum to my system than I've ever heard before.
