Kendall features a 1" anodized aluminum Tweeter, a 5.25" Midrange and 2 x 6.5" Woven Kevlar Woofer. On the other hand, the Forte IV features a 1" titanium-diaphragm compression horn-loaded Tweeter, a 1.75" Midrange and 1 x 12" Fibercomposite Woofer.
Frequency Response
Kendall has a frequency range of 25-23k Hz whereas Forte IV has a frequency range of 38-20k Hz. With a minimum frequency of 25Hz, the Kendall can go significantly deeper on the low side and provide stronger bass compared to the Forte IV's min frequency of 38Hz.
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
Kendall and Forte IV have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Kendall sensitivity is rated at 96 dB and the Forte IV's is at 99 dB. This 3 dB difference makes the Klipsch Forte IV a more sensitive speaker compared to KLH Kendall, 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.
Kendall can handle a max power of 250 watts RMS, whereas Forte IV has a max power handling value of 100 watts RMS, 150 watts less than the Kendall.
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 Kendall and Forte 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 KLH Kendall's and Klipsch Forte IV's external dimensions. KLH Kendall has external dimensions of 1021.0 x 212.0 x 380.0mm (40-3/16 x 8-5/16 x 14-15/16inch) whereas Klipsch Forte IV has external dimensions of 909.0 x 423.0 x 331.0mm (35-3/4 x 16-5/8 x 13inch).
Klipsch Forte IV is 112mm shorter and 49mm less deeper than KLH Kendall but it is also 211mm wider.
Below you can see the front view size comparison of KLH Kendall and Klipsch Forte 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 KLH Kendall is approximately 805.6cm2 / 124.9inch2 and base area of the Klipsch Forte IV is approximately 1400.1cm2 / 217.0inch2. The Kendall requires 42% less surface area than the Forte IV 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 KLH Kendall weighs 22.14kg / 48.7lbs and the Klipsch Forte IV weighs 32.73kg / 72lbs. This makes the Forte IV 48% heavier than the Kendall.

These sit in different price classes - Klipsch Forte IV costs roughly 3.3x what KLH Kendall does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass |
A |
KLH Kendall digs deeper - 25Hz against 38Hz. |
| Amplifier needs |
B |
Klipsch Forte IV is more sensitive (99dB vs 96dB), so it goes louder on the same amplifier. |
| Headroom |
A |
KLH Kendall takes more power (250W vs 100W) - more in hand in a big room. |
| Size |
depends |
KLH Kendall is easier to place; Klipsch Forte IV is bigger, which usually goes with fuller bass. Your room decides. |
| Cabinet |

KLH Kendall: bi-amping; Klipsch Forte IV: bi-amping. Klipsch Forte IV sits in a wider range (12 models), so a matched surround system is easier later. |
| Price |
A |
KLH Kendall is cheaper - $1,500 against $4,998, about 70% less; arguably a different class. |

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?
KLH Kendall has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 38Hz anyway, so judge these on the other rows instead. In a large or open-plan room, Klipsch Forte IV has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, KLH Kendall is the easier speaker to get right.
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.
