AK6 features a 1" polyimide diaphragm compression Tractrix horn Tweeter, a 2" Midrange and 1 x 15" fiber-composite with a trihedral exponential folded horn Woofer. 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
AK6 has a frequency range of 33-20k Hz whereas Cornwall IV has a frequency range of 34-20k Hz. With a minimum frequency of 33Hz, the AK6 can go slightly deeper then the Cornwall IV's min frequency of 34Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
AK6 and Cornwall IV have the same Impedance of 8 ohms but where they differ is the sensitivity levels. AK6 sensitivity is rated at 105 dB and the Cornwall IV's is at 102 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.
Sensitivity
Floor-standing Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
AK6 and Cornwall IV have the same power range of up to 100 watts.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.

Starting with a popular amplifier — change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Both AK6 and Cornwall IV features dual binding post speaker terminals for bi-amping or bi-wiring.
Physical Specs
The size of a speaker can sometimes be 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 AK6's and Klipsch Cornwall IV's external dimensions. Klipsch Klipschorn AK6 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 AK6 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 AK6 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 AK6 is approximately 5700.9cm2 / 883.6inch2 and base area of the Klipsch Cornwall IV is approximately 2533.4cm2 / 392.7inch2. The AK6 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 AK6 weighs 100.00kg / 220lbs and the Klipsch Cornwall IV weighs 44.55kg / 98lbs. This makes the AK6 124% heavier than the Cornwall IV.
Here is a comparison of how AK6 and Cornwall IV's weights compare with the average, max and min weights in Passive Floor-standing class.

Siblings in Klipsch's Heritage series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass |
evenly matched |
Much the same reach (33Hz vs 34Hz). |
| Amplifier needs |
A |
Klipsch Klipschorn AK6 is more sensitive (105dB vs 102dB), so it goes louder on the same amplifier. |
| Headroom |
evenly matched |
Similar power handling (100W vs 100W). |
| Size |
depends |
Klipsch Cornwall IV is easier to place; Klipsch Klipschorn AK6 is bigger, which usually goes with fuller bass. Your room decides. |
| Cabinet |
depends |
Sealed vs Ported. Sealed is tighter and happier near a wall; ported digs lower but wants space behind it. |
| Expandability |
depends |
Klipsch Klipschorn AK6: bi-amping; Klipsch Cornwall IV: bi-amping. |
| Price |
B |
Klipsch Cornwall IV is cheaper - $6,598 against $16,498, about 60% less; arguably a different class. |

B Klipsch Cornwall IV
depends neither is better in the abstract - it turns on your room, placement or how you will use them.
Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
Klipsch Klipschorn AK6 is ahead, but only on 1 of the measured areas, and it costs about 60% more. That is a lot of money for a narrow margin on paper - Klipsch Cornwall IV looks like the sensible buy unless something else about the Klipsch Klipschorn AK6 appeals to you. In a large or open-plan room, Klipsch Klipschorn AK6 has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Klipsch Cornwall IV is the easier speaker to get right. If your amplifier is modest, vintage or valve-based, Klipsch Klipschorn AK6 is the safer partner - the other will want more current or more watts to sound its best.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
