In this review, we will be comparing L600 and Kendall, two Passive Floor-standing speakers from Polk Audio and KLH. Let's have a brief look at the main features
of Polk L600 and KLH Kendall first before getting into our more
detailed comparison.
In the following sections, we will get into more detail in order to better understand how the Polk L600 and KLH Kendall compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

L600 features a 1" Pinnacle Ring Radiator Tweeter , a 5.25" Midrange and 2 x 7" Polypropylene Woofer with a Crossover frequency at 410Hz and 2900Hz. On the other hand, the Kendall features a 1" anodized aluminum Tweeter , a 5.25" Midrange and 2 x 6.5" Woven Kevlar Woofer .
Frequency Response
L600 has a frequency range of 34-38k Hz whereas Kendall has a frequency range of 25-23k Hz. With a minimum frequency of 25Hz, the Kendall can go significantly deeper on the low side and provide stronger bass compared to the L600's min frequency of 34Hz.
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

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
L600 is a 4 ohms speaker compared to the Kendall 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 L600 can provide this impedance level.
These two speakers also have different sensitivity levels. L600 sensitivity is rated at 86 dB and the Kendall's is rated at 96 dB. This 10 dB difference makes the KLH Kendall a more sensitive speaker compared to Polk L600, 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.
L600 can handle a max power of 300 watts RMS from the amp the whereas Kendall has a max power handling value of watts RMS, 300 watts less than the L600.
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 L600 and Kendall features dual binding post speaker terminals for bi-amping or bi-wiring.
Polk L600's Binding post terminals allows Bi-amping or bi-wiring
KLH Kendall's Binding post terminals allows 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 Polk L600's and KLH Kendall's external dimensions. Polk L600 has external dimensions of 1182.0 x 331.0 x 426.0mm ( 46-1/2 x 13 x 16-3/4inch) whereas 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) .
Polk L600 is clearly the larger of the two speakers. Its body is 119mm wider, 161mm taller and 46mm deeper than KLH Kendall.
Below you can see the front view size comparison of Polk L600 and KLH Kendall 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 Polk L600 is approximately 1410.1cm2 / 218.6inch2 and base area of the KLH Kendall is approximately 805.6cm2 / 124.9inch2. The L600 requires 75% more surface area than the Kendall 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 Polk L600 weighs 35.30kg / 77.7lbs and the KLH Kendall weighs 22.14kg / 48.7lbs. This makes the L600 59% heavier than the Kendall.
Here is a comparison of how L600 and Kendall's weights compare with the average, max and min weights in Passive Floor-standing class.
