History
What size room are the DALI Opticon 2 II and Dali Opticon VOKAL II speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)

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.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf 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
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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Opticon 2 MK2 and Opticon VOKAL MK2 have the same power range of 30-150 watts.
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
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.

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 Opticon 2 II's and Dali Opticon VOKAL II's external dimensions. DALI Opticon 2 II has external dimensions of 351.0 x 196.0 x 297.0mm (13-13/16 x 7-11/16 x 11-11/16inch) whereas Dali Opticon VOKAL II has external dimensions of 202.0 x 435.0 x 313.0mm (7-15/16 x 17-1/8 x 12-5/16inch).
DALI Opticon 2 II is 239mm narrower and 16mm less deeper than Dali Opticon VOKAL II but it is also 149mm taller.
Below you can see the front view size comparison of DALI Opticon 2 II and Dali Opticon VOKAL II in scale.
