Drivers

One of the fundamental differences between these two speakers is that Sonetto CII is a 3-way design whereas the Sonus faber Sonetto III G2 is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the Sonetto CII and the Sonetto CII can provide this impedance level.

Power Range

Power range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.

Sonetto CII can handle a max power of 300 watts RMS from the amp the whereas Sonus faber Sonetto III G2 has a max power handling value of 280 watts RMS, 20 watts less than the Sonetto CII.

Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters such as Impedance, sensitivity and system efficiencies.

Input Type and Bi-Amping / Bi-Wiring

Both Sonetto CII and Sonus faber Sonetto III G2 features dual binding post speaker terminals for bi-amping or bi-wiring.
