RP-504C II features a 1" titanium Tractrix Horn Tweeter and 4 x 5.25" Cerametallic cone Woofer with a Crossover frequency at 1950 Hz. On the other hand, the Oberon Vokal features a 1-1/8" ultra-light soft textile Soft-Dome Tweeter and 2 x 5.25" Wood Fiber Woofer with a Crossover frequency at 2600Hz.
Frequency Response
RP-504C II has a frequency range of 50-25k Hz whereas Oberon Vokal has a frequency range of 47-26k Hz. With a minimum frequency of 47Hz, the Oberon Vokal can go slightly deeper then the RP-504C II's min frequency of 50Hz.
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 Center Channel class in our database.
Low Frequency
Center Channel Speakers
High Frequency
Center Channel Speakers
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
RP-504C II is a 8 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. RP-504C II sensitivity is rated at 96 dB and the Oberon Vokal's is rated at 89.5 dB. This 6 dB difference makes the Klipsch RP-504C II a more sensitive speaker compared to DALI Oberon 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.
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
RP-504C II 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
RP-504C II 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 Klipsch RP-504C II 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 Klipsch RP-504C II's and DALI Oberon Vokal's external dimensions. Klipsch RP-504C II has external dimensions of 177.0 x 818.0 x 385.0mm ( 6-15/16 x 32-3/16 x 15-1/8inch) 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) .
Klipsch RP-504C II is clearly the larger of the two speakers. Its body is 375mm wider, 15mm taller and 91mm deeper than DALI Oberon Vokal.
Below you can see the front view size comparison of Klipsch RP-504C II 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 Klipsch RP-504C II is approximately 3149.3cm2 / 488.1inch2 and base area of the DALI Oberon Vokal is approximately 1302.4cm2 / 201.9inch2. The RP-504C II requires 142% more surface area than the Oberon Vokal which gives it a small disadvantage on placement in tight spaces.
