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. On the other hand, the Oberon On-Wall features a 1.14" Soft-Dome Tweeter and 1 x 5.25" Wood fibre Woofer with a Crossover frequency at 2100Hz.
Frequency Response
Oberon GRAND Vokal has a frequency range of 45-26k Hz whereas Oberon On-Wall has a frequency range of 55-26k Hz. With a minimum frequency of 45Hz, the Oberon GRAND Vokal can go significantly deeper on the low side and provide stronger bass compared to the Oberon On-Wall's min frequency of 55Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Center Channel class in our database.
Low Frequency
Center Channel 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 GRAND Vokal is a 4 ohms speaker compared to the Oberon On-Wall 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 On-Wall's is rated at 87 dB. This 4 dB difference makes the DALI Oberon GRAND Vokal a more sensitive speaker compared to DALI Oberon On-Wall, 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. 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 On-Wall has a max power handling value of 100 watts RMS, 100 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.

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
