In Reply to: Tue. Class D has all sorts of artifacts higher up the spectrum. TONS of artifacts. posted by toothpaste on May 30, 2018 at 14:52:52:
Switching noise starts at the switching frequency and extends up from there in a sequence of harmonics. Typical switching frequencies for Class D amplifiers are in the 300-1000 KHz range. Your tweeters will not reproduce the noise. If it's not well suppressed it is most likely to impact medium-wave broadcast (AM radio), shortwave, and amateur radio bands. And it could impact nearby audio equipment that is unusually susceptible to RFI.
