Can anyone tell me the best frequencies to set my high and low pass filters at? i've got 2 6^9s and a 12" sub. The base is ok but i'm having real trouble setting the high pass filter for the 6^9's.
That depends entirely on your speakers and even a bit you personal taste, although that is more the EQ's department. We need a lot more detail if we are going to be able to help you. Eg - do you know the specs for the speakers? you need to setup your crossover to suit the speakers response range and if you can set the drop off to closely match that of the speakers freq response curve.
