What size room are the Mission 770 and Buchardt S400 MKII 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:

Mission 770 features a 1.25" Soft-Dome Tweeter and 1 x 8" mineral-loaded polyproylene Woofer with a Crossover frequency at 2900Hz. On the other hand, the 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.
Frequency Response
Mission 770 has a frequency range of 42-20,000 Hz whereas S400 MKII has a frequency range of 33-40k 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 Mission 770's min frequency of 42Hz.
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
Mission 770 is a 8 ohms speaker compared to the S400 MKII 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 S400 MKII can provide this impedance level.
On the other hand, they have the same sensitivity of 88 dBdB.

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 Mission 770's and Buchardt S400 MKII's external dimensions. Mission 770 has external dimensions of 590 x 279.4 x 301mm ( 23-1/4inch x 11-13/16inch x 12-11/16inch ) whereas Buchardt S400 MKII has external dimensions of 365.0 x 180.0 x 280.0mm ( 14.4 x 7 x 11inch) .
Mission 770 is clearly the larger of the two speakers. Its body is 99.4mm wider, 225mm taller and 21mm deeper than Buchardt S400 MKII.
Below you can see the front view size comparison of Mission 770 and Buchardt S400 MKII 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 Mission 770 is approximately 841.0cm2 / 130.4inch2 and base area of the Buchardt S400 MKII is approximately 504.0cm2 / 78.1inch2. The Mission 770 requires 67% more surface area than the S400 MKII which gives it a small disadvantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Mission 770 weighs 27.20kg / 59.8lbs and the Buchardt S400 MKII weighs 7.50kg / 16.5lbs. This makes the Mission 770 263% heavier than the S400 MKII.
Here is a comparison of how Mission 770 and S400 MKII's weights compare with the average, max and min weights in Passive Bookshelf class.
