I have the PXB:5K0.
I want to change the cutoff frequency from 5K to 3.5K just like the PXB:3k5.
I just need to know how to pull this off.
Simply put, what parts do I need to order?
Thanks |

It seems easy enough. Right? |

You're going to have to buy the parts for the low pass and the high pass of course, too, it's not just one part.
If you're going to do this, it's my opinion you'd do a lot better to pull some impedance plots for your woofer/horn and do something tailored to your rig. Add some padding too potentially (unless you've got the model with the attenuator already I guess? .

I figured I could convert my PXB:5K0 that I have laying around to 3.5.
If it isn't gonna be easy, then I'll just buy the PXB3k5.
Yes, I have the attenuator, It looks like the biger 100 watt l-pad. |

Good on you for at least attempting to recycle... |
