Amplification Warning

Polk states 8 ohms nominal, "compatible with 8, 6 and 4 ohm outputs", and a 3.6-ohm minimum — the lowest dip of the 8-ohm-labelled speakers in this batch. Combined with a 30 W lower power limit, this is not a speaker for a small class-D desktop amplifier: it wants an amplifier whose current does not fold at 4 ohms.
