Sub has low pass filter 40-200 range. EQ with built in crossover has range from 30-200. Speakers are 3 way with 15 inch woofers. I have set the LPF around 100. Sounds great but it sounds like the 3 ways are still getting a lot of bass to them even if I turn crossover to 200 setting. Is there a reason they are still getting a lot of bass? Is there an ideal setting for the crossover? 75-80? New at this and want to make sure I optimize the settings. Thanks for any help you can provide.
