In this review, we will be comparing Oberon 5 and R-620F, two Passive Floor-standing speakers from DALI and Klipsch. Let's have a brief look at the main features
of DALI Oberon 5 and Klipsch R-620F first before getting into our more
detailed comparison.
What size room are the DALI Oberon 5 and Klipsch R-620F 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 5 and Klipsch R-620F compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Oberon 5 features a 1.125" Soft-Dome Tweeter and 2 x 5.25" Wood Fiber Woofer with a Crossover frequency at 2400Hz. On the other hand, the R-620F features a 1.0" Tweeter and 2 x 6.5" Copper-spun IMG Woofer with a Crossover frequency at 2000Hz.
Frequency Response
Oberon 5 has a frequency range of 39-26k Hz whereas R-620F has a frequency range of 38-21k Hz. With a minimum frequency of 38Hz, the R-620F can go slightly deeper then the Oberon 5's min frequency of 39Hz.
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 Floor-standing 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 5 is a 6 ohms speaker compared to the R-620F which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. Oberon 5 sensitivity is rated at 88 dB and the R-620F's is rated at 96 dB. This 8 dB difference makes the Klipsch R-620F a more sensitive speaker compared to DALI Oberon 5, 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 5 can handle a max power of 150 watts RMS from the amp the whereas R-620F has a max power handling value of 100 watts RMS, 50 watts less than the Oberon 5.
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
Oberon 5 features Post type posts and R-620F has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Oberon 5 and R-620F 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 Oberon 5's and Klipsch R-620F's external dimensions. DALI Oberon 5 has external dimensions of 832.0 x 202.0 x 277.0mm ( 32-3/4 x 7-15/16 x 10-7/8inch) whereas Klipsch R-620F has external dimensions of 1021.0 x 239.0 x 369.0mm ( 40-3/16 x 9-3/8 x 14-1/2inch) .
Klipsch R-620F is clearly the larger of the two speakers. Its body is 37mm wider, 189mm taller and 92mm deeper than DALI Oberon 5.
Below you can see the front view size comparison of DALI Oberon 5 and Klipsch R-620F 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 5 is approximately 559.5cm2 / 86.7inch2 and base area of the Klipsch R-620F is approximately 881.9cm2 / 136.7inch2. The Oberon 5 requires 37% less surface area than the R-620F 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 Oberon 5 weighs 10.80kg / 23.8lbs and the Klipsch R-620F weighs 18.64kg / 41lbs. This makes the R-620F 73% heavier than the Oberon 5.
Here is a comparison of how Oberon 5 and R-620F's weights compare with the average, max and min weights in Passive Floor-standing class.
