For me, the topic of volumio and FusionDsp is completely new.
I have installed volumio with FusionDsp on an old RPi 2 B Rev. 1.1 and connected it to an amplifier. On my terrace are 2 KEF Ventura 4 outdoor speakers mounted:
KEF
Product Specifications
Dimensions (HxWxD) in mm 230x171x154
Cross Over Frequency 3.5kHz
Recommended Amp Power 10 - 80 Watts
HF Driver 19mm Tweeter
LF Driver 115mm
Enclosure Type Two-Way Sealed Box
Frequency range 75Hz - 20kHz
With these I would like to boost the bass range. What is the best way to do this?
