VELA BS 403 features a " handmade JET 5 folded ribbon tweeter Tweeter and 1 x 6" Aluminum/Paper Woofer . 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
VELA BS 403 has a frequency range of 41-50k 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 VELA BS 403's min frequency of 41Hz.
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
VELA BS 403 and S400 MKII have the same Impedance of 4 ohms but where they differ is the sensitivity levels. VELA BS 403 sensitivity is rated at 86 dB and the S400 MKII's is at 88 dB. This 2 dB difference makes the Buchardt S400 MKII a more sensitive speaker compared to ELAC VELA BS 403, 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 VELA BS 403 and the VELA BS 403 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.
VELA BS 403 can handle a max power of 200 watts RMS from the amp the whereas VELA BS 403 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 ELAC VELA BS 403's and Buchardt S400 MKII's external dimensions. ELAC VELA BS 403 has external dimensions of 361.0 x 191.0 x 239.0mm ( 24-28inch x 7-1/2inch x 9-3/8inch ) whereas Buchardt S400 MKII has external dimensions of 365.0 x 180.0 x 280.0mm ( 14.4 x 7 x 11inch) .
ELAC VELA BS 403 is 4mm shorter and 41mm less deeper than Buchardt S400 MKII but it is also 11mm 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 ELAC VELA BS 403 is approximately 456.5cm2 / 70.8inch2 and base area of the Buchardt S400 MKII is approximately 504.0cm2 / 78.1inch2. The VELA BS 403 requires 9% less surface area than the S400 MKII which gives it a small advantage on placement in tight spaces.
