Rubikore 8 features a 1.14" Hybrid dome + planar Tweeter and 3 x 6.5" Wood fibre Woofer with a Crossover frequency at 500 / 800 / 2400 / 14000Hz. On the other hand, the 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.
Frequency Response
Rubikore 8 and Rubikore 6 has exactly the same frequency range of 38-34k Hz.
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
Rubikore 8 and Rubikore 6 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Rubikore 8 sensitivity is rated at 90.5 dB and the Rubikore 6's is at 88.5 dB. This 2 dB difference makes the DALI Rubikore 8 a more sensitive speaker compared to DALI Rubikore 6, hence will play louder with the same amount of watts.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the Rubikore 8 and the Rubikore 8 can provide this impedance level.

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.
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
Rubikore 8 features Binding post type posts and Rubikore 6 has a Binding post type posts. None of these speakers 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 DALI Rubikore 8's and DALI Rubikore 6's external dimensions. DALI Rubikore 8 has external dimensions of ( ) whereas DALI Rubikore 6 has external dimensions of ( ) .
In this case, we can see that DALI Rubikore 8 and DALI Rubikore 6 have the exact same height, width and thickness.
