In this review, we will be comparing DALI Spektor 2 and Oberon 3, two Passive Bookshelf speakers by DALI Let's have a brief look at the main features
of DALI Spektor 2 and DALI Oberon 3 first before getting into our more
detailed comparison.
What size room are the DALI Spektor 2 and DALI Oberon 3 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:
In the following sections, we will get into more detail in order to better understand how the DALI Spektor 2 and DALI Oberon 3 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

DALI Spektor 2 features a 1" Soft-Dome Tweeter and 1 x 5.25" Wood Fiber Woofer with a Crossover frequency at 2600Hz. On the other hand, the Oberon 3 features a 1.125" Soft-Dome Tweeter and 1 x 7" Wood Fiber Woofer with a Crossover frequency at 2400Hz.
Frequency Response
DALI Spektor 2 has a frequency range of 54-26k Hz whereas Oberon 3 has a frequency range of 47-26k Hz. With a minimum frequency of 47Hz, the Oberon 3 can go significantly deeper on the low side and provide stronger bass compared to the DALI Spektor 2's min frequency of 54Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Bookshelf class in our database.

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 2 and Oberon 3 have the same Impedance of 6 ohms but where they differ is the sensitivity levels. DALI Spektor 2 sensitivity is rated at 84.5 dB and the Oberon 3's is at 87 dB. This 2 dB difference makes the DALI Oberon 3 a more sensitive speaker compared to DALI Spektor 2, 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 2 can handle a max power of 150 watts RMS from the amp the whereas DALI Spektor 2 has a max power handling value of 100 watts RMS , 50 watts less than the Oberon 3.
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 2 features Post type posts and Oberon 3 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both DALI Spektor 2 and Oberon 3 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 Spektor 2's and DALI Oberon 3's external dimensions. DALI Spektor 2 has external dimensions of 292.0 x 170.0 x 228.0mm ( 11.5 x 6.7 x 9.4inch) whereas 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) .
DALI Oberon 3 is clearly the larger of the two speakers. Its body is 31mm wider, 58mm taller and 82mm deeper than DALI Spektor 2.
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 2 is approximately 387.6cm2 / 60.1inch2 and base area of the DALI Oberon 3 is approximately 623.1cm2 / 96.6inch2. The DALI Spektor 2 requires 38% less surface area than the Oberon 3 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 2 weighs 4.20kg / 9.2lbs and the DALI Oberon 3 weighs 6.32kg / 13.9lbs. This makes the Oberon 3 50% heavier than the DALI Spektor 2.
Here is a comparison of how DALI Spektor 2 and Oberon 3's weights compare with the average, max and min weights in Passive Bookshelf class.
