RECOMMENDED: Frequency response (audio band, wide band, ~ 330 ohm load 0.550 Vrms OPTIONAL: Vrms to clip ~33 ohm load. NECESSARY: Do at least 33 ohm or 330 ohm. May depend on the type of amp. For example, a tube amp should prioritize on the 330 load. OTL amps we might not bother with 33 ohm load. It's all context.
