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
Cornwall IV and AK6 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Cornwall IV sensitivity is rated at 102 dB and the AK6's is at 105 dB. This 3 dB difference makes the Klipsch Klipschorn AK6 a more sensitive speaker compared to Klipsch Cornwall IV, 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.
Cornwall IV and AK6 has the same power range of up to 100 watts.
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 Cornwall IV and AK6 features dual binding post speaker terminals for bi-amping or bi-wiring.
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.

Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the Klipsch Cornwall IV is approximately 2533.4cm2 / 392.7inch2 and base area of the Klipsch Klipschorn AK6 is approximately 5700.9cm2 / 883.6inch2. The Cornwall IV requires 56% less surface area than the AK6 which gives it a small advantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Klipsch Cornwall IV weighs 44.55kg / 98lbs and the Klipsch Klipschorn AK6 weighs 100.00kg / 220lbs. This makes the AK6 124% heavier than the Cornwall IV.
