Oberon 3 features a 1.125" Soft-Dome Tweeter and 1 x 7" Wood Fiber Woofer with a Crossover frequency at 2400Hz. On the other hand, the Oberon GRAND Vokal features a 1-1/8" ultra-light soft textile Soft-Dome Tweeter and 2 x 7" Wood Fiber Woofer with a Crossover frequency at 2500Hz.
Frequency Response
Oberon 3 has a frequency range of 47-26k Hz whereas Oberon GRAND Vokal has a frequency range of 45-26k Hz. With a minimum frequency of 45Hz, the Oberon GRAND Vokal can go slightly deeper then the Oberon 3's min frequency of 47Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. 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.
Sensitivity
Bookshelf Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Oberon GRAND Vokal can handle a max power of 200 watts RMS, whereas Oberon 3 has a max power handling value of 150 watts RMS, 50 watts less than the Oberon GRAND Vokal.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
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.
Physical Specs
The size of a speaker can sometimes be 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 GRAND Vokal'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 GRAND Vokal has external dimensions of 201 x 700 x 310mm (7.9 x 27.5 x 12.2inch).
Below you can see the front view size comparison of DALI Oberon 3 and DALI Oberon GRAND Vokal in scale.
