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 and Oberon 7 have the same Impedance of 6 ohms but where they differ is the sensitivity levels. Oberon 3 sensitivity is rated at 87 dB and the Oberon 7's is at 88.5 dB. This 2 dB difference makes the DALI Oberon 7 a more sensitive speaker compared to DALI Oberon 3, hence will play louder with the same amount of watts.
Sensitivity

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 180 watts RMS from the amp the whereas Oberon 3 has a max power handling value of 150 watts RMS , 30 watts less than the Oberon 7.
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 Post type posts and Oberon 7 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Oberon 3 and Oberon 7 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.
Physical Specs
Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare DALI Oberon 3's and DALI Oberon 7's external dimensions. DALI Oberon 3 has external dimensions of 350.0 x 201.0 x 310.0mm ( 13-3/4 x 7-7/8 x 12-3/16inch) whereas DALI Oberon 7 has external dimensions of 1016.0 x 200.0 x 329.0mm ( 40 x 7-7/8 x 12-15/16inch) .
DALI Oberon 3 is 666mm shorter and 19mm less deeper than DALI Oberon 7 but it is also 1mm wider.
Below you can see the front view size comparison of DALI Oberon 3 and DALI Oberon 7 in scale.
