Terminology correction - LFE should be Subwoofer in speaker configuration and probably in other DSP functions

“LFE does not equal subwoofer”

“The Misunderstood 0.1 LFE Channel in 5.1 Digital Surround Sound”

In short:
LFE = Explicit content LF content in a n.1 content
Subwoofer = The speaker/channel that would eventually reproduce/contain LFE content/Crossovered content from other speakers/Combination of both.

Unless I’m mistaken it seems like Roon has fallen (in terminology only) to this common misnomer mistake.
