History
What size room are the Buchardt E50 and Buchardt S400 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:

400 sq. ft / 36 m2.
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 E50 and Buchardt S400 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

E50 features a 1" Custom Scanspeak textile dome waveguide Tweeter and 1 x 6.5" PURIFI Extended Stroke Woofer with a Crossover frequency at 2000Hz. On the other hand, the S400 features a 0.74" Custom fine weave soft fabric textile aluminum waveguide Tweeter and 1 x 6" paper Woofer with a Crossover frequency at 2000Hz.
Frequency Response
E50 has a frequency range of 36-30k HZ whereas S400 has a frequency range of 33-40 kHz. With a minimum frequency of 33Hz, the S400 can go slightly deeper then the E50's min frequency of 36Hz.
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
E50 and S400 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. E50 sensitivity is rated at 85 dB and the S400's is at 88 dB. This 3 dB difference makes the Buchardt S400 a more sensitive speaker compared to Buchardt E50, hence will play louder with the same amount of watts.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the E50 and the E50 can provide this impedance level.

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.
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 E50's and Buchardt S400's external dimensions. Buchardt E50 has external dimensions of 395 x 190 x 284 mm ( 15.5 x 7.5 x 11.1 inch) whereas Buchardt S400 has external dimensions of 375 x 180 x 245mm ( 14.75 x 7 x 9.6inch) .
Buchardt E50 is clearly the larger of the two speakers. Its body is 10mm wider, 20mm taller and 39mm deeper than Buchardt S400.
Below you can see the front view size comparison of Buchardt E50 and Buchardt S400 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 E50 is approximately 539.6cm2 / 83.6inch2 and base area of the Buchardt S400 is approximately 441.0cm2 / 68.4inch2. The E50 requires 22% more surface area than the S400 which gives it a small disadvantage 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:
