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 3 is a 6 ohms speaker compared to the Oberon GRAND Vokal which has a nominal impedance of 4 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 3 sensitivity is rated at 87 dB and the Oberon GRAND Vokal's is rated at 91 dB. This 4 dB difference makes the DALI Oberon GRAND 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 3 can handle a max power of 200 watts RMS from the amp the whereas Oberon 3 has a max power handling value of 150 watts RMS , 50 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 3 features Binding post type posts and Oberon GRAND Vokal has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Oberon 3 and Oberon GRAND Vokal have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
