R7 features a 1" aluminum Dome Tweeter , a 5" Midrange and 2 x 6.5" Hybrid Aluminum Woofer with a Crossover frequency at 400Hz and 2900Hz. On the other hand, the VELA FS 409 features a ---" handmade JET 5 folded ribbon Tweeter , a 6" Midrange and 2 x 7" Aluminum/Paper Woofer .
Frequency Response
R7 has a frequency range of 48-28k Hz whereas VELA FS 409 has a frequency range of 28-50k Hz. With a minimum frequency of 28Hz, the VELA FS 409 can go significantly deeper on the low side and provide stronger bass compared to the R7's min frequency of 48Hz.
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 Floor-standing class in our database.

High Frequency
Floor-standing 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
R7 is a 8 ohms speaker compared to the VELA FS 409 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 VELA FS 409 can provide this impedance level.
These two speakers also have different sensitivity levels. R7 sensitivity is rated at 88 dB and the VELA FS 409's is rated at 89 dB. This 1 dB difference makes the ELAC VELA FS 409 a more sensitive speaker compared to KEF R7, 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.
R7 can handle a max power of 250 watts RMS from the amp the whereas VELA FS 409 has a max power handling value of 200 watts RMS, 50 watts less than the R7.
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 R7 and VELA FS 409 features dual binding post speaker terminals for bi-amping or bi-wiring.

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 R7's and ELAC VELA FS 409's external dimensions. KEF R7 has external dimensions of 1113.0 x 200.0 x 389.0mm ( 43-13/16 x 8 x 15-5/16inch) whereas ELAC VELA FS 409 has external dimensions of 1331.0 x 278.0 x 345.0mm ( 52-3/8 x 10-15/16 x 13-9/16inch) .
KEF R7 is 78mm narrower and 218mm shorter than ELAC VELA FS 409 but it is also 44mm deeper.
Below you can see the front view size comparison of KEF R7 and ELAC VELA FS 409 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 KEF R7 is approximately 778.0cm2 / 120.6inch2 and base area of the ELAC VELA FS 409 is approximately 959.1cm2 / 148.7inch2. The R7 requires 19% less surface area than the VELA FS 409 which gives it a small advantage on placement in tight spaces.
