Drivers

One of the fundamental differences between these two speakers is that Q Acoustics 5040 is a 2-way design whereas the Kendall is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

Driver Q Acoustics 5040 KLH Kendall
Driver Setup 2-way 3-way
Tweeter 1-inch 1-inch
Midrange - 1 x 5.25-inch
Woofer 2 x 5-inch 2 x 6.5-inch

Q Acoustics 5040 features a 1" Soft-dome Tweeter and 2 x 5" Continuous Curved Cone Woofer with a Crossover frequency at 2500 Hz. 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

Q Acoustics 5040 has a frequency range of 39-30k 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 Q Acoustics 5040's min frequency of 39Hz.

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.

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

Q Acoustics 5040 is a 6 ohms speaker compared to the Kendall which has a nominal impedance of 8 ohms.

These two speakers also have different sensitivity levels. Q Acoustics 5040 sensitivity is rated at 91.5 dB and the Kendall's is rated at 96 dB. This 4 dB difference makes the KLH Kendall a more sensitive speaker compared to Q Acoustics 5040, 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.

Q Acoustics 5040 can handle a max power of 150 watts RMS from the amp the whereas Kendall has a max power handling value of watts RMS, 150 watts less than the Q Acoustics 5040.

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

Kendall features Binding post posts which make bi-amping or bi-wiring possible. Q Acoustics 5040 has a Binding post which doesn't feature bi-amping/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 Q Acoustics 5040's and KLH Kendall's external dimensions. Q Acoustics 5040 has external dimensions of 969.0 x 362.0 x 293.0mm ( 38-1/8inch x 14-1/4inch x 11-1/2inch ) 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) .

Q Acoustics 5040 is 52mm shorter and 87mm less deeper than KLH Kendall but it is also 150mm wider.

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 Q Acoustics 5040 is approximately 1060.7cm2 / 164.4inch2 and base area of the KLH Kendall is approximately 805.6cm2 / 124.9inch2. The Q Acoustics 5040 requires 32% 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 Q Acoustics 5040 weighs 18.05kg / 39.7lbs and the KLH Kendall weighs 22.14kg / 48.7lbs. This makes the Kendall 23% heavier than the Q Acoustics 5040.

Here is a comparison of how Q Acoustics 5040 and Kendall's weights compare with the average, max and min weights in Passive Floor-standing class.
