Beginner DSP Build with ADAU1701 – Need Optimization Advice

Hi everyone,

I'm new to SigmaStudio and DSP audio design in general, and I’ve just finished setting up my first project. I’d love to hear feedback from more experienced users on how I can improve or optimize my design.

What I'm using:

DSP board: Wondom JAB5 (ADAU1701)

Tweeter: FaitalPro HF111

Woofer: FaitalPro 8FE200 4 Ohm

Enclosure: 12 mm MDF with a vented design

Ports: See WinISD screenshots for tuning (around 69 Hz)

What I’ve implemented:

Separate signal paths for LoFi and HiFi

Parametric EQs for woofer and tweeter (double precision)

Crossover + compressor blocks

Dynamic bass boost

GPIO volume control with soft slew rate

My goals:

Get the best possible sound quality out of this setup

Keep things power-safe (limiting, clipping prevention)

Below are some screenshots of my SigmaStudio project and my enclosure simulation in WinISD. Any suggestions regarding filter alignment, limiter setup, compressor thresholds, volume control techniques, or structural DSP flow would be greatly appreciated.

Thanks in advance for your help!
