Kendall features a 1" anodized aluminum Tweeter, a 5.25" Midrange and 2 x 6.5" Woven Kevlar Woofer. On the other hand, the Uni-Fi FS U5 Slim features a 1" soft dome Tweeter, a 4" Midrange and 3 x 5.25" Aluminum Woofer.
Frequency Response
Kendall has a frequency range of 25-23k Hz whereas Uni-Fi FS U5 Slim has a frequency range of 42-25k Hz. With a minimum frequency of 25Hz, the Kendall can go significantly deeper on the low side and provide stronger bass compared to the Uni-Fi FS U5 Slim's min frequency of 42Hz.
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 is a 8 ohms speaker compared to the Uni-Fi FS U5 Slim which has a nominal impedance of 4 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 Uni-Fi FS U5 Slim can provide this impedance level.
These two speakers also have different sensitivity levels. Kendall sensitivity is rated at 96 dB and the Uni-Fi FS U5 Slim's is rated at 85 dB. This 11 dB difference makes the KLH Kendall a more sensitive speaker compared to ELAC Uni-Fi FS U5 Slim, 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 Uni-Fi FS U5 Slim has a max power handling value of 140 watts RMS, 110 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
Kendall features Binding post posts which make bi-amping or bi-wiring possible. Uni-Fi FS U5 Slim has a Binding post which doesn't feature bi-amping/bi-wiring.
