Impedance and Sensitivity
Oberon GRAND Vokal is a 4 ohms speaker compared to the Oberon 7 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 GRAND Vokal can provide this impedance level.
These two speakers also have different sensitivity levels. Oberon GRAND Vokal sensitivity is rated at 91 dB and the Oberon 7's is rated at 88.5 dB. This 2 dB difference makes the DALI Oberon GRAND Vokal a more sensitive speaker compared to DALI Oberon 7, 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 GRAND Vokal can handle a max power of 200 watts RMS from the amp the whereas Oberon 7 has a max power handling value of 180 watts RMS, 20 watts less than the Oberon GRAND Vokal.
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 GRAND Vokal features Post type posts and Oberon 7 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
