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

Sib Evo is a 6 ohms speaker compared to the Sib-T 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 Sib-T can provide this impedance level.

On the other hand, they have the same sensitivity of 90 dBdB.

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 Focal Sib Evo's and Focal Sib-T's external dimensions. Focal Sib Evo has external dimensions of 251.0 x 162.0 x 164.0mm ( 28-36inch x 6-3/8inch x 6-7/16inch ) whereas Focal Sib-T has external dimensions of 64.0 x 143.0 x 170.0mm ( 2-1/2 x 5-5/8 x 6-11/16inch) .

Focal Sib-T is 19mm narrower and 187mm shorter than Focal Sib Evo but it is also 6mm deeper.

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 Focal Sib Evo is approximately 265.7cm2 / 41.2inch2 and base area of the Focal Sib-T is approximately 243.1cm2 / 37.7inch2. The Sib Evo requires 9% more surface area than the Sib-T 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 Focal Sib Evo weighs 1.80kg / 4lbs and the Focal Sib-T weighs 2.60kg / 5.7lbs. This makes the Sib-T 44% heavier than the Sib Evo.

Here is a comparison of how Sib Evo and Sib-T's weights compare with the average, max and min weights in Passive Bookshelf class.
