Professor Thump Posted June 25, 2009 Share Posted June 25, 2009 The term "pole" or "order" can be used interchangebly. This represents a 6 dB shift in the slope per octave and a 90 degree shift in phase. It is easier to understand with pictures but the end result is that if the phase of both drivers in the cabinet are not similar the acoustic wave will not sum. Michael is correct in looking at the phase by changing the polarity of the woofer. You also have to be careful with some drivers like JBL which uses reverse polarity for their notation. So the problems you may have now is at least three fold. 1. Drivers are 90 degrees out of phase. Eitherway you flip you are out 90 degrees. This is why you need a 3 rd order or 3 poles on the HF. 2. Values are incorrect on the crossover. If the values of the caps and inductors don't match the Klipsch schematic the crossover won't work exactly right. 3. Driver frequency response is incorrect. If this doesn't match the crossover you have more problems. Any or all of the previous conditions are likely to have occured. But hey, that is half the fun! The pursuit of fixing a forelorn speaker.
