None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.

Impedance and Sensitivity

Sonetto CI and Sonetto II have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Sonetto CI sensitivity is rated at 90 dB and the Sonetto II's is at 87 dB. This 3 dB difference makes the Sonus Sonetto Center I a more sensitive speaker compared to Sonus Sonetto II, hence will play louder with the same amount of watts.

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 CI and the Sonetto CI 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.

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 CI and Sonetto II features dual binding post speaker terminals for bi-amping or bi-wiring.
