What size room are the Buchardt S400 MKII and DALI Oberon 1 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:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
In the following sections, we will get into more detail in order to better understand how the Buchardt S400 MKII and DALI Oberon 1 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

S400 MKII features a 0.74" fine weave soft fabric textile aluminum waveguide Tweeter and 1 x 6" paper Woofer with a Crossover frequency at 1800Hz. On the other hand, the Oberon 1 features a 1.125" Soft-Dome Tweeter and 1 x 5.25" Wood Fiber Woofer with a Crossover frequency at 2800Hz.
Frequency Response
S400 MKII has a frequency range of 33-40k HZ whereas Oberon 1 has a frequency range of 51-26k Hz. With a minimum frequency of 33Hz, the S400 MKII can go significantly deeper on the low side and provide stronger bass compared to the Oberon 1's min frequency of 51Hz.
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.

High Frequency
Bookshelf 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
S400 MKII is a 4 ohms speaker compared to the Oberon 1 which has a nominal impedance of 6 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 S400 MKII can provide this impedance level.
These two speakers also have different sensitivity levels. S400 MKII sensitivity is rated at 88 dB and the Oberon 1's is rated at 86 dB. This 2 dB difference makes the Buchardt S400 MKII 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.
S400 MKII can handle a max power of 200 watts RMS from the amp the whereas Oberon 1 has a max power handling value of 100 watts RMS, 100 watts less than the S400 MKII.
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.
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 Buchardt S400 MKII's and DALI Oberon 1's external dimensions. Buchardt S400 MKII has external dimensions of 365.0 x 180.0 x 280.0mm ( 14.4 x 7 x 11inch) whereas 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) .
Buchardt S400 MKII is clearly the larger of the two speakers. Its body is 16mm wider, 90mm taller and 52mm deeper than DALI Oberon 1.
Below you can see the front view size comparison of Buchardt S400 MKII and DALI Oberon 1 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 Buchardt S400 MKII is approximately 504.0cm2 / 78.1inch2 and base area of the DALI Oberon 1 is approximately 373.9cm2 / 58.0inch2. The S400 MKII requires 35% more surface area than the Oberon 1 which gives it a small disadvantage on placement in tight spaces.
