Can slope be TOO high?
type: item
description: In an active crossover system, can the slope be TOO high? The norm seems to be 4th order (24dB/oct), but Marchand has an 8th order unit at 48dB/oct. What are the downsides to using an extremely steep slope and are there systems that are better suited to this than others? thanks, Gar.
