Drivers
One of the fundamental differences between these two speakers is that R3 Meta is a 3-way design whereas the VELA BS 403 is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

R3 Meta features a 1" Aluminum with MAT absorber Hard-Dome Tweeter , a 5" Midrange and 1 x 6.5" Hybrid Aluminum Woofer with a Crossover frequency at 420Hz and 2300Hz. On the other hand, the VELA BS 403 features a " handmade JET 5 folded ribbon tweeter Tweeter and 1 x 6" Aluminum/Paper Woofer .
Frequency Response
R3 Meta has a frequency range of 58-28k Hz whereas VELA BS 403 has a frequency range of 41-50k Hz. With a minimum frequency of 41Hz, the VELA BS 403 can go significantly deeper on the low side and provide stronger bass compared to the R3 Meta's min frequency of 58Hz.
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
R3 Meta and VELA BS 403 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. R3 Meta sensitivity is rated at 87 dB and the VELA BS 403's is at 86 dB. This 1 dB difference makes the KEF R3 Meta 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 R3 Meta and the R3 Meta 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.
R3 Meta can handle a max power of 180 watts RMS from the amp the whereas VELA BS 403 has a max power handling value of 100 watts RMS, 80 watts less than the R3 Meta.
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.
Input Type and Bi-Amping / Bi-Wiring
Both R3 Meta and VELA BS 403 features dual binding post speaker terminals for bi-amping or bi-wiring.
KEF R3 Meta's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring
ELAC VELA BS 403's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
R3 Meta has a rear firing port whereas VELA BS 403 has a bottom firing ports. ELAC VELA BS 403's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to KEF R3 Meta with its rear-firing port.
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 KEF R3 Meta's and ELAC VELA BS 403's external dimensions. KEF R3 Meta has external dimensions of 423.0 x 202.0 x 337.0mm ( 16-5/8-inch x 7-15/16-inch x 13-1/4-inch) whereas 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 ) .
KEF R3 Meta is clearly the larger of the two speakers. Its body is 11mm wider, 62mm taller and 98mm deeper than ELAC VELA BS 403.
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 KEF R3 Meta is approximately 680.7cm2 / 105.5inch2 and base area of the ELAC VELA BS 403 is approximately 456.5cm2 / 70.8inch2. The R3 Meta requires 49% more surface area than the VELA BS 403 which gives it a small disadvantage on placement in tight spaces.
