History
What size room are the Focal Theva No1 and Focal Theva No2 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

400 sq. ft / 36 m2.
Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)

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 Theva No2 features a 1" TNF Al/Mg inverted dome Tweeter, a 6.5" Midrange and 2 x 6.5" Slatefiber Woofer with a Crossover frequency at 280 Hz - 2900 Hz.
Frequency Response
Theva No1 has a frequency range of 58-28kHz whereas Theva No2 has a frequency range of 53-28kHz. With a minimum frequency of 53Hz, the Theva No2 can go significantly deeper on the low side and provide stronger bass compared to the Theva No1's min frequency of 58Hz.
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 Theva No2 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Theva No1 sensitivity is rated at 89 dB and the Theva No2's is at 90 dB. This 1 dB difference makes the Focal Theva No2 a more sensitive speaker compared to Focal Theva No1, hence will play louder with the same amount of watts.

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.
Theva No2 can handle a max power of 200 watts RMS, whereas Theva No1 has a max power handling value of 120 watts RMS, 80 watts less than the Theva No2.
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. Theva No2 has a Binding post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Theva No1 and Theva No2 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 Theva No2'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 Theva No2 has external dimensions of 931.0 x 191.0 x 353.0mm (365/8 x 71/2 x 137/8).
Focal Theva No1 is 540mm shorter and 92mm less deeper than Focal Theva No2 but it is also 22mm 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 Theva No2 is approximately 674.2cm2 / 104.5inch2. The Theva No1 requires 18% less surface area than the Theva No2 which gives it a small advantage on placement in tight spaces.
