factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

Theva No1 features a 1" TNF Al/Mg inverted dome Tweeter and 1 x 6.5" Slatefiber Woofer with a Crossover frequency at 3000 Hz. On the other hand, the Chora 806 features a 1" TNV2 AI/Mg inverted dome Tweeter and 1 x 6.5" Slatefiber Woofer with a Crossover frequency at 3000Hz.
Frequency Response
Theva No1 has a frequency range of 58-28kHz whereas Chora 806 has a frequency range of 55-28k Hz.
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
Theva No1 and Chora 806 have the same Impedance of 8 ohms and their sensitivity is also same at 89 dB.
Sensitivity
Bookshelf Speakers
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.
Both handle the same maximum of 120 watts RMS, though Theva No1 is rated 25-120 watts and Chora 806 25 - 120 watts.
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
Theva No1 features Binding post posts which make bi-amping or bi-wiring possible. Chora 806 has a Binding post which doesn't feature bi-amping/bi-wiring.
Focal Theva No1's Binding post terminals allows Bi-amping or bi-wiring

Cabinet Type and Port Position
Both Theva No1 and Chora 806 have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
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 Focal Theva No1's and Focal Chora 806's external dimensions. Focal Theva No1 has external dimensions of 391.0 x 213.0 x 261.0mm (153/8 x 83/8 x 101/4) whereas Focal Chora 806 has external dimensions of 431.0 x 210.0 x 270.0mm (17 x 8.25 x 10.7inch).
Focal Theva No1 is 40mm shorter and 9mm less deeper than Focal Chora 806 but it is also 3mm 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 Focal Theva No1 is approximately 555.9cm2 / 86.2inch2 and base area of the Focal Chora 806 is approximately 567.0cm2 / 87.9inch2. The Theva No1 requires 2% less surface area than the Chora 806 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 Focal Theva No1 weighs 6.82kg / 15lbs and the Focal Chora 806 weighs 7.35kg / 16.2lbs. This makes the Chora 806 8% heavier than the Theva No1.
Here is a comparison of how Theva No1 and Chora 806's weights compare with the average, max and min weights in Passive Bookshelf class.

Both are Focal, from different ranges - so the house sound is shared and the differences are mostly in scale, engineering and price.
| Area | Better | Why |
|---|
| Bass |
evenly matched |
Much the same reach (58Hz vs 58Hz). |
| Amplifier needs |
evenly matched |
Similar sensitivity (89dB vs 89dB) - both want much the same power. |
| Headroom |
evenly matched |
Similar power handling (120W vs 120W). |
| Size |
depends |
Similar cabinet size - neither is easier to fit. |

depends neither is better in the abstract - it turns on your room, placement 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?
Focal Theva No1 has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does.
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.
