Drivers
One of the fundamental differences between these two speakers is that Opticon VOKAL MK2 is a 3-way design whereas the Opticon 2 MK2 is a 2-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.

Opticon VOKAL MK2 features a 17 x 45 mm ribbon + 1.125" Soft-dome + ribbon Hybrid Tweeter and 1 x 6.5" Wood Fiber Woofer with a Crossover frequency at 2400Hz and 14.000Hz. On the other hand, the Opticon 2 MK2 features a 1.125" Soft-Dome Tweeter and 1 x 6.5" Wood Fiber Woofer with a Crossover frequency at 2000Hz.
Frequency Response
Opticon VOKAL MK2 has a frequency range of 47-30k Hz whereas Opticon 2 MK2 has a frequency range of 59-25k Hz. With a minimum frequency of 47Hz, the Opticon VOKAL MK2 can go significantly deeper on the low side and provide stronger bass compared to the Opticon 2 MK2's min frequency of 59Hz.
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 Center Channel class in our database.

High Frequency
Center Channel Speakers
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
Opticon VOKAL MK2 and Opticon 2 MK2 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Opticon VOKAL MK2 sensitivity is rated at 88 dB and the Opticon 2 MK2's is at 86.5 dB. This 1 dB difference makes the Dali Opticon VOKAL II a more sensitive speaker compared to DALI Opticon 2 II, 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 Opticon VOKAL MK2 and the Opticon VOKAL MK2 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.
Opticon VOKAL MK2 and Opticon 2 MK2 has the same power range of 30-150 watts.
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
Opticon VOKAL MK2 features Post type posts and Opticon 2 MK2 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.
