Drivers

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

Opticon 2 MK2 features a 1.125" Soft-Dome Tweeter and 1 x 6.5" Wood Fiber Woofer with a Crossover frequency at 2000Hz. On the other hand, the 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.

Frequency Response

Opticon 2 MK2 has a frequency range of 59-25k Hz whereas Opticon VOKAL MK2 has a frequency range of 47-30k 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.

Impedance and Sensitivity

Opticon 2 MK2 and Opticon VOKAL MK2 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Opticon 2 MK2 sensitivity is rated at 86.5 dB and the Opticon VOKAL MK2's is at 88 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 2 MK2 and the Opticon 2 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 2 MK2 and Opticon VOKAL 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 2 MK2 features Binding post type posts and Opticon VOKAL MK2 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.
