In this review, we will be comparing Oberon 1 and EVO4.2, two Passive Bookshelf speakers from DALI and Wharfedale. Let's have a brief look at the main features
of DALI Oberon 1 and Wharfedale EVO4.2 first before getting into our more
detailed comparison.
What size room are the DALI Oberon 1 and Wharfedale EVO4.2 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 Oberon 1 and Wharfedale EVO4.2 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that Oberon 1 is a 2-way design whereas the EVO4.2 is a 3-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 1 features a 1.125" Soft-Dome Tweeter and 1 x 5.25" Wood Fiber Woofer with a Crossover frequency at 2800Hz. On the other hand, the EVO4.2 features a 1.18x2.36" AMT (Ribbon) Tweeter , a 2" Midrange and 1 x 6.5" Kevlar Woofer .
Frequency Response
Oberon 1 has a frequency range of 51-26k Hz whereas EVO4.2 has a frequency range of 54-22k Hz. With a minimum frequency of 51Hz, the Oberon 1 can go slightly deeper then the EVO4.2'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
Oberon 1 is a 6 ohms speaker compared to the EVO4.2 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. Oberon 1 sensitivity is rated at 86 dB and the EVO4.2's is rated at 88 dB. This 2 dB difference makes the Wharfedale EVO4.2 a more sensitive speaker compared to DALI Oberon 1, 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.
Oberon 1 can handle a max power of 120 watts RMS from the amp the whereas Oberon 1 has a max power handling value of 100 watts RMS , 20 watts less than the EVO4.2.
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
EVO4.2 features Post posts which make bi-amping or bi-wiring possible. Oberon 1 has a Post which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Oberon 1 has a rear firing port whereas EVO4.2 has a bottom firing ports. Wharfedale EVO4.2's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to DALI Oberon 1 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 Oberon 1's and Wharfedale EVO4.2's external dimensions. DALI Oberon 1 has external dimensions of 275.0 x 164.0 x 228.0mm ( 10-13/16 x 6-7/16 x 8-15/16inch) whereas Wharfedale EVO4.2 has external dimensions of 455.0 x 250.0 x 350.0mm ( 17.9 x 9.8 x 13.7inch) .
Wharfedale EVO4.2 is clearly the larger of the two speakers. Its body is 86mm wider, 180mm taller and 122mm deeper than DALI Oberon 1.
Below you can see the front view size comparison of DALI Oberon 1 and Wharfedale EVO4.2 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 Oberon 1 is approximately 373.9cm2 / 58.0inch2 and base area of the Wharfedale EVO4.2 is approximately 875.0cm2 / 135.6inch2. The Oberon 1 requires 57% less surface area than the EVO4.2 which gives it a small advantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:
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 Oberon 1 weighs 4.18kg / 9.2lbs and the Wharfedale EVO4.2 weighs 13.40kg / 29.5lbs. This makes the EVO4.2 221% heavier than the Oberon 1.
Here is a comparison of how Oberon 1 and EVO4.2's weights compare with the average, max and min weights in Passive Bookshelf class.
