When I first got my dsp back late 2018 the LW crossover and the BW crossover sounded way different now since I updated my dayton firmware both sound similar specially on the sub with the LW crossover sounding a lil louder at the crossover point when it suppose to be 6db down at that point whats going on...?

Upgrades change things, have you measured the system to see what its doing? I also use a dayton and haven't had that issue.

Did u upgrade the firmware to the latest one?I measured the voltage drop @ crossover point on both LR and BW 24db slope and they are similar which it shouldnt be so.....ill try to find my back up firmware and see if i can revert back to how it was b4...

Yup, latest firmware on. Try the revert and see what happens. I just saw you got yours in 2018, mine is a "newer" one, got it 2019.

there was a post on the facebook group about an issue with the xovers and recommended updating to the recent firmware. I could go find it if you like.

Would be good. Saw this from 2019:
The new DSP-408 firmware update is now available for download and here's a link to an instructional video to properly install the update:

How to Update your DSP-408!

A link to the update is located on the "More Info" section below the video.

This update is also available on Parts Express DSP-408 webpage.

This firmware corrects the crossover slope issues that some were experiencing.

The newest software addresses an error message bug and a high shelf filter issue.
