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
DALI Spektor Vokal is a 6 ohms speaker compared to the Oberon 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 Vokal can provide this impedance level.
These two speakers also have different sensitivity levels. DALI Spektor Vokal sensitivity is rated at 87 dB and the Oberon Vokal's is rated at 89.5 dB. This 3 dB difference makes the DALI Oberon Vokal a more sensitive speaker compared to DALI Spektor Vokal, 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.
DALI Spektor Vokal can handle a max power of 150 watts RMS from the amp the whereas DALI Spektor Vokal has a max power handling value of 120 watts RMS , 30 watts less than the Oberon 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
DALI Spektor Vokal features Binding post type posts and Oberon Vokal has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
DALI Spektor Vokal has a rear firing port whereas Oberon Vokal has a front firing ports. DALI Oberon Vokal's front-firing port gives more flexibility in placement in regards to proximity to walls compared to DALI Spektor Vokal with its rear-firing port.
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 Spektor Vokal's and DALI Oberon Vokal's external dimensions. DALI Spektor Vokal has external dimensions of 152.0 x 435.0 x 204.0mm ( 6 x 17.1 x 8inch) whereas DALI Oberon Vokal has external dimensions of 162.0 x 443.0 x 294.0mm ( 6-3/8 x 17-7/16 x 11-9/16inch) .
DALI Oberon Vokal is clearly the larger of the two speakers. Its body is 8mm wider, 10mm taller and 90mm deeper than DALI Spektor Vokal.
Below you can see the front view size comparison of DALI Spektor Vokal and DALI Oberon Vokal in scale.

Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the DALI Spektor Vokal is approximately 887.4cm2 / 137.5inch2 and base area of the DALI Oberon Vokal is approximately 1302.4cm2 / 201.9inch2. The DALI Spektor Vokal requires 32% less surface area than the Oberon Vokal which gives it a small advantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The DALI Spektor Vokal weighs 5.30kg / 11.7lbs and the DALI Oberon Vokal weighs 7.45kg / 16.4lbs. This makes the Oberon Vokal 41% heavier than the DALI Spektor Vokal.
