[QUOTE="Jay Barracato, post: 2952, member: 24"] I appreciate the conversation as I try to move from technician "rule of thumb plus experience" to engineer "theory based decisions supported by measurements". Most of my experience with setting crossovers involves making sure manufacturers recommendations are correctly followed. This question came up on the other boards, where I really expected that if I was off base, I would hear about it. Distilling the whole thread about the K10 HF came down to "it is always better to match the polarity of the two sources because it gives better transient response". Based on this argument, the other person was amazed that I wasn't willing to give up a whopping chunk of on axis amplitude response, in favor of slightly better response extremely off axis plus this "improved" transient response that showed no where in the data. Given that the fastest notes in music ever played still consist of over 100 waveforms at a 2000 hz crossover, I have a hard time believing that the initial movement of the vibration source is audible. I can buy that the direction of the cone makes a difference at 80 hz but not in the HF. Any thoughts? [/QUOTE]
