HTM6 S3 features a 1" Titanium Decoupled Double Dome Tweeter and 2 x 5" Continuum Woofer . 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
HTM6 S3 has a frequency range of 72-28k Hz whereas Oberon Vokal has a frequency range of 47-26k Hz. With a minimum frequency of 47Hz, the Oberon Vokal can go significantly deeper on the low side and provide stronger bass compared to the HTM6 S3's min frequency of 72Hz.
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
HTM6 S3 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. HTM6 S3 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 BW HTM6 S3 , 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.
HTM6 S3 can handle a max power of 150 watts RMS from the amp the whereas HTM6 S3 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
HTM6 S3 features Binding post posts which make bi-amping or bi-wiring possible. Oberon Vokal has a Binding post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
HTM6 S3 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 BW HTM6 S3 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 BW HTM6 S3 's and DALI Oberon Vokal's external dimensions. BW HTM6 S3 has external dimensions of 160.0 x 480.0 x 283.0mm ( 6.3 x 18.9 x 11.2inch) 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) .
BW HTM6 S3 is 2mm shorter and 11mm less deeper than DALI Oberon Vokal but it is also 37mm wider.
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 BW HTM6 S3 is approximately 1358.4cm2 / 210.6inch2 and base area of the DALI Oberon Vokal is approximately 1302.4cm2 / 201.9inch2. The HTM6 S3 requires 4% more surface area than the Oberon Vokal which gives it a small disadvantage on placement in tight spaces.
