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.
Low Frequency
Center Channel Speakers
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 6 MK2 have the same Impedance of 4 ohms and their sensitivity is also same at 88 dB.
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 can handle a max power of 200 watts RMS from the amp the whereas Opticon VOKAL MK2 has a max power handling value of 150 watts RMS , 50 watts less than the Opticon 6 MK2.
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 6 MK2 features Post posts which make bi-amping or bi-wiring possible. Opticon VOKAL MK2 has a Binding post which doesn't feature bi-amping/bi-wiring.
