What size room are the Buchardt S400 and Jamo S 801 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 and Jamo S 801 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

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. On the other hand, the S 801 features a 1" Soft-Dome Tweeter and 1 x 4" Aluminized Polyfiber Woofer .
Frequency Response
S400 has a frequency range of 33-40 kHz whereas S 801 has a frequency range of 76-26k Hz. With a minimum frequency of 33Hz, the S400 can go significantly deeper on the low side and provide stronger bass compared to the S 801's min frequency of 76Hz.
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.

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 is a 4 ohms speaker compared to the S 801 which has a nominal impedance of 8 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 can provide this impedance level.
These two speakers also have different sensitivity levels. S400 sensitivity is rated at 88 dB and the S 801's is rated at 85 dB. This 3 dB difference makes the Buchardt S400 a more sensitive speaker compared to Jamo S 801, 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 can handle a max power of 200 watts RMS from the amp the whereas S 801 has a max power handling value of 60 watts RMS, 140 watts less than the S400.
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's and Jamo S 801's external dimensions. Buchardt S400 has external dimensions of 375 x 180 x 245mm ( 14.75 x 7 x 9.6inch) whereas Jamo S 801 has external dimensions of 285.0 x 156.0 x 163.0mm ( 11.2 x 6.1 x 6.4inch) .
Buchardt S400 is clearly the larger of the two speakers. Its body is 24mm wider, 90mm taller and 82mm deeper than Jamo S 801.
Below you can see the front view size comparison of Buchardt S400 and Jamo S 801 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 is approximately 441.0cm2 / 68.4inch2 and base area of the Jamo S 801 is approximately 254.3cm2 / 39.4inch2. The S400 requires 73% more surface area than the S 801 which gives it a small disadvantage on placement in tight spaces.
