In this review, we will be comparing Rubikore 6 and Kendall, two Passive Floor-standing speakers from DALI and KLH.
Let's have a brief look at the main features
of DALI Rubikore 6 and KLH Kendall first before getting into our more
detailed comparison.

The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
One of the fundamental differences between these two speakers is that Rubikore 6 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.

Rubikore 6 features a 1.14" Hybrid dome + planar Tweeter and 2 x 6.5" Wood fibre Woofer with a Crossover frequency at 800 / 2600 / 14000Hz. 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
Rubikore 6 has a frequency range of 38-34k 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 Rubikore 6'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
Rubikore 6 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 Rubikore 6 can provide this impedance level.
These two speakers also have different sensitivity levels. Rubikore 6 sensitivity is rated at 88.5 dB and the Kendall's is rated at 96 dB. This 7 dB difference makes the KLH Kendall a more sensitive speaker compared to DALI Rubikore 6, 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. 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 Rubikore 6 has a max power handling value of 200 watts RMS, 50 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.
Which plays louder on your 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 Rubikore 6 and Kendall 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 DALI Rubikore 6's and KLH Kendall's external dimensions. DALI Rubikore 6 has external dimensions of 990 x 200 x 380 mm () 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).
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.

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 DALI Rubikore 6 is approximately 760.0cm2 / 117.8inch2 and base area of the KLH Kendall is approximately 805.6cm2 / 124.9inch2. The Rubikore 6 requires 6% less surface area than the Kendall which gives it a small advantage on placement in tight spaces.
