VELA BS 403 features a " handmade JET 5 folded ribbon tweeter Tweeter and 1 x 6" Aluminum/Paper Woofer. On the other hand, the 705 S3 features a 1" Decoupled Carbon Dome Tweeter and 1 x 6.5" Continuum Woofer.
Frequency Response
VELA BS 403 has a frequency range of 41-50k Hz whereas 705 S3 has a frequency range of 50-28k 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 705 S3's min frequency of 50Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
VELA BS 403 is a 4 ohms speaker compared to the 705 S3 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 VELA BS 403 can provide this impedance level.
These two speakers also have different sensitivity levels. VELA BS 403 sensitivity is rated at 86 dB and the 705 S3's is rated at 88 dB. This 2 dB difference makes the B&W 705 S3 a more sensitive speaker compared to ELAC VELA BS 403, hence will play louder with the same amount of watts.
Sensitivity

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
705 S3 can handle a max power of 120 watts RMS, whereas VELA BS 403 has a max power handling value of 100 watts RMS, 20 watts less than the 705 S3.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Both VELA BS 403 and 705 S3 features dual binding post speaker terminals for bi-amping or bi-wiring.
ELAC VELA BS 403's Binding post terminals allows Bi-amping or bi-wiring
B&W 705 S3's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
VELA BS 403 has a bottom firing port whereas 705 S3 has a rear firing ports. ELAC VELA BS 403's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to B&W 705 S3 with its rear-firing port.
Physical Specs
The size of a speaker can sometimes be 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 B&W 705 S3'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 B&W 705 S3 has external dimensions of 413.0 x 192.0 x 337.0mm (16.3-inch x 7.6-inch x 13.3-inch).
B&W 705 S3 is clearly the larger of the two speakers. Its body is 1mm wider, 52mm 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 ELAC VELA BS 403 is approximately 456.5cm2 / 70.8inch2 and base area of the B&W 705 S3 is approximately 647.0cm2 / 100.3inch2. The VELA BS 403 requires 29% less surface area than the 705 S3 which gives it a small advantage 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 ELAC VELA BS 403 weighs 7.10kg / 15.6lbs and the B&W 705 S3 weighs 9.58kg / 21.1lbs. This makes the 705 S3 35% heavier than the VELA BS 403.
Here is a comparison of how VELA BS 403 and 705 S3's weights compare with the average, max and min weights in Passive Bookshelf class.

A generation apart: B&W 705 S3 is the newer design, against a 2018 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass | A | ELAC VELA BS 403 digs deeper - 41Hz against 50Hz. A subwoofer would even that out. |
| Amplifier needs | B | B&W 705 S3 is more sensitive (88dB vs 86dB), so it goes louder on the same amplifier. |
| Amplifier match | B | B&W 705 S3 is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | evenly matched | Similar power handling (100W vs 120W). |
| Size | depends | ELAC VELA BS 403 is easier to place; B&W 705 S3 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | ELAC VELA BS 403: bi-amping; B&W 705 S3: bi-amping. B&W 705 S3 sits in a wider range (8 models), so a matched surround system is easier later. |
| Price | A | ELAC VELA BS 403 is cheaper - $2,899 against $3,398, about 15% less. |
A ELAC VELA BS 403 B B&W 705 S3
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: B&W 705 S3 measures better, ELAC VELA BS 403 costs about about 17% more% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 50Hz anyway, so judge these on the other rows instead. In a large or open-plan room, B&W 705 S3 has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, ELAC VELA BS 403 is the easier speaker to get right.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
