I would really like to understand the relationship between signal level decibels and speaker spl decibels, regardless of whether it is necessary. No explanation I have heard so far makes any sense to me (my fault). What I really want to know is this. Suppose I am sending a constant digital...

I am experimenting with building active speakers using FIR filters in a DSP. I need to adjust the level of the tweeter, mid range and woofer audio streams to allow for the different sensitivity of the drivers. I had assumed this would be a simple matter of finding the difference in sensitivity...

What other cards are you referring to specifically? I can always buy yet another one. Anything to get this working!

All my Creative cards (G6, GC7 and X4) have both optical inputs and outputs. Only the Asus Xonar has only an output (coax). That's not the problem in this case. I did forget to mention one likely issue, and that is running Linux on the Raspberry PI. This means I cannot use the Creative software...

I have an audio setup for active speakers using a headless Raspberry PI 400 running brutefir (FIR filtering), with an Asus Xonar U7 USB DAC providing multiple audio streams to drive three stereo amps and in turn two tweeters, two mid woofers and a sub. The audio feed to this setup comes from a...
