History
What size room are the DALI Oberon 9 and DALI Oberon GRAND Vokal speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
One of the fundamental differences between these two speakers is that Oberon 9 is a 3-way design whereas the Oberon GRAND Vokal is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

Oberon 9 features a 1.125" Soft-Dome Tweeter, a 7" Midrange and 2 x 9" Wood Fiber Woofer with a Crossover frequency at 780Hz and 3400Hz. 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 9 has a frequency range of 35-26k Hz whereas Oberon GRAND Vokal has a frequency range of 45-26k Hz. With a minimum frequency of 35Hz, the Oberon 9 can go significantly deeper on the low side and provide stronger bass compared to the Oberon GRAND Vokal's min frequency of 45Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing 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 9 and Oberon GRAND Vokal have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Oberon 9 sensitivity is rated at 90.5 dB and the Oberon GRAND Vokal's is at 91 dB.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the Oberon 9 and the Oberon 9 can provide this impedance level.
Sensitivity
Floor-standing 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 9 can handle a max power of 400 watts RMS, whereas Oberon GRAND Vokal has a max power handling value of 200 watts RMS, 200 watts less than the Oberon 9.
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 9 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 9 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 9's and DALI Oberon GRAND Vokal's external dimensions. DALI Oberon 9 has external dimensions of 1172.0 x 260.0 x 407.0mm (46-1/8 x 10-1/4 x 16inch) whereas DALI Oberon GRAND Vokal has external dimensions of 201 x 700 x 310mm (7.9 x 27.5 x 12.2inch).
DALI Oberon GRAND Vokal is 971mm shorter and 97mm less deeper than DALI Oberon 9 but it is also 440mm wider.
