AK7 features a 1" polyimide diaphragm compression Tractrix horn Tweeter , a 3" Midrange and 1 x 15" fiber-composite with a trihedral exponential folded horn Woofer with a Crossover frequency at 380Hz - 290Hz. On the other hand, the Cornwall IV features a 1" titanium-diaphragm compression horn-loaded Tweeter , a 1.75" Midrange and 1 x 15" Fiber composite Woofer .
Frequency Response
AK7 has a frequency range of 34-19k Hz whereas Cornwall IV has a frequency range of 34-20k Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Floor-standing class in our database.

High Frequency
Floor-standing Speakers
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
AK7 and Cornwall IV have the same Impedance of 8 ohms but where they differ is the sensitivity levels. AK7 sensitivity is rated at 103 dB and the Cornwall IV's is at 102 dB. This 1 dB difference makes the Klipsch Klipschorn AK7 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.
AK7 and Cornwall IV 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 AK7 and Cornwall IV 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. In this section, we are going to compare Klipsch Klipschorn AK7's and Klipsch Cornwall IV's external dimensions. Klipsch Klipschorn AK7 has external dimensions of 1347.0 x 794.0 x 718.0mm ( 53 x 31-1/4 x 28-1/4inch) whereas Klipsch Cornwall IV has external dimensions of 966.0 x 643.0 x 394.0mm ( 38 x 25-5/16 x 15-1/2inch) .
Klipsch Klipschorn AK7 is clearly the larger of the two speakers. Its body is 151mm wider, 381mm taller and 324mm deeper than Klipsch Cornwall IV.
Below you can see the front view size comparison of Klipsch Klipschorn AK7 and Klipsch Cornwall IV in scale.

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 Klipschorn AK7 is approximately 5700.9cm2 / 883.6inch2 and base area of the Klipsch Cornwall IV is approximately 2533.4cm2 / 392.7inch2. The AK7 requires 125% more surface area than the Cornwall IV which gives it a small disadvantage 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 Klipschorn AK7 weighs 118.00kg / 259.6lbs and the Klipsch Cornwall IV weighs 44.55kg / 98lbs. This makes the AK7 165% heavier than the Cornwall IV.
Here is a comparison of how AK7 and Cornwall IV's weights compare with the average, max and min weights in Passive Floor-standing class.
