OPTICON 2 MK2

Amplification Warning

A 6.5-inch two-way bookshelf on a 4-ohm nominal with a single 2 kHz crossover. 86.5 dB at 2.83 V is the low end of the range for this size; combined with the 4-ohm rating it means the honest watt-scale figure is around 83.5 dB, so this is a speaker that wants current, not a receiver's headline wattage.
