Frequency Response
Oberon Vokal and Oberon 3 has exactly the same frequency range of 47-26k Hz.
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
Oberon Vokal is a 4 ohms speaker compared to the Oberon 3 which has a nominal impedance of 6 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Oberon Vokal can provide this impedance level.
These two speakers also have different sensitivity levels. Oberon Vokal sensitivity is rated at 89.5 dB and the Oberon 3's is rated at 87 dB. This 3 dB difference makes the DALI Oberon Vokal a more sensitive speaker compared to DALI Oberon 3, hence will play louder with the same amount of watts.

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.
Oberon Vokal and Oberon 3 has the same power range of 25-150 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
Oberon Vokal features Post type posts and Oberon 3 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.
