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 8 MK2 and Opticon VOKAL 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 8 MK2 and the Opticon 8 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 8 MK2 can handle a max power of 300 watts RMS from the amp the whereas Opticon VOKAL MK2 has a max power handling value of 150 watts RMS, 150 watts less than the Opticon 8 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 8 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.
