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

S400 MKII is a 4 ohms speaker compared to the Aon 3 Bookshelf Monitor which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the S400 MKII can provide this impedance level.

These two speakers also have different sensitivity levels. S400 MKII sensitivity is rated at 88 dB and the Aon 3 Bookshelf Monitor's is rated at 90 dB. This 2 dB difference makes the GoldenEar Aon 3 a more sensitive speaker compared to Buchardt S400 MKII, hence will play louder with the same amount of watts.

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.

S400 MKII can handle a max power of 250 watts RMS from the amp the whereas S400 MKII has a max power handling value of 200 watts RMS , 50 watts less than the Aon 3 Bookshelf Monitor.

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.

Physical Specs

Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Buchardt S400 MKII's and GoldenEar Aon 3's external dimensions.
