The factory supplied Goertz networks are designed to come into play at 160 KHz. As you might guess, this is WAY out of our hearing range of what is supposedly 20 KHz. Since i only know of one speaker that actually could make it out to 100 KHz, i don't think that we have to worry about the results being audible. Shoot, many components and most sources are way down by the time they get to 100 KHz let alone 150+ KHz. In fact, some are specifically designed for very limited bandwidth. Sean
