What size room are the Focal Theva No3-D and Klipsch RP-8000F II 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:

Drivers
One of the fundamental differences between these two speakers is that Theva No3-D is a 3-way design whereas the RP-8000F II is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

Theva No3-D 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 270 Hz - 2700 Hz. On the other hand, the RP-8000F II features a 1" titanium Tractrix Horn Tweeter and 2 x 8" Cerametallic cone Woofer with a Crossover frequency at 1630 Hz.
Frequency Response
Theva No3-D has a frequency range of 48-28kHz whereas RP-8000F II has a frequency range of 32-25k Hz. With a minimum frequency of 32Hz, the RP-8000F II can go significantly deeper on the low side and provide stronger bass compared to the Theva No3-D's min frequency of 48Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing 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 No3-D and RP-8000F II have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Theva No3-D sensitivity is rated at 91 dB and the RP-8000F II's is at 98 dB. This 7 dB difference makes the Klipsch RP-8000F II a more sensitive speaker compared to Focal Theva No3-D, hence will play louder with the same amount of watts.
Sensitivity
Floor-standing 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 No3-D can handle a max power of 250 watts RMS, whereas RP-8000F II has a max power handling value of 150 watts RMS, 100 watts less than the Theva No3-D.
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
RP-8000F II features Binding post posts which make bi-amping or bi-wiring possible. Theva No3-D has a Binding post which doesn't feature bi-amping/bi-wiring.

Klipsch RP-8000F II's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Theva No3-D and RP-8000F II 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 No3-D's and Klipsch RP-8000F II's external dimensions. Focal Theva No3-D has external dimensions of 1020.0 x 213.0 x 388.0mm (401/8 x 83/8 x 151/4) whereas Klipsch RP-8000F II has external dimensions of 1097.0 x 277.0 x 447.0mm (43-3/16 x 10-7/8 x 17-9/16inch).
Klipsch RP-8000F II is clearly the larger of the two speakers. Its body is 64mm wider, 77mm taller and 59mm deeper than Focal Theva No3-D.
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 No3-D is approximately 826.4cm2 / 128.1inch2 and base area of the Klipsch RP-8000F II is approximately 1238.2cm2 / 191.9inch2. The Theva No3-D requires 33% less surface area than the RP-8000F II 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 No3-D weighs 21.82kg / 48lbs and the Klipsch RP-8000F II weighs 28.00kg / 61.6lbs. This makes the RP-8000F II 28% heavier than the Theva No3-D.
Here is a comparison of how Theva No3-D and RP-8000F II's weights compare with the average, max and min weights in Passive Floor-standing class.

These sit in different price classes - Focal Theva No3-D costs roughly 1.7x what Klipsch RP-8000F II does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | B | Klipsch RP-8000F II digs deeper - 32Hz against 48Hz. |
| Amplifier needs | B | Klipsch RP-8000F II is more sensitive (98dB vs 91dB), so it goes louder on the same amplifier. |
| Headroom | A | Focal Theva No3-D takes more power (250W vs 150W) - more in hand in a big room. |
| Size | depends | Focal Theva No3-D is easier to place; Klipsch RP-8000F II is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | B | Focal Theva No3-D: Atmos drivers; Klipsch RP-8000F II: bi-amping and Atmos drivers. Klipsch RP-8000F II sits in a wider range (10 models), so a matched surround system is easier later. |
| Price | B | Klipsch RP-8000F II is cheaper - $1,798 against $2,998, about 40% less; arguably a different class. |
A Focal Theva No3-D B Klipsch RP-8000F II
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?
Klipsch RP-8000F II is the easier recommendation: it leads on most of the measured areas and costs less. Take Focal Theva No3-D if its size, looks or fit in your room suit you better. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 48Hz anyway, so judge these on the other rows instead. Match it to your room: we rate Focal Theva No3-D the better fit for a very large room, and Klipsch RP-8000F II for a mid-size room.
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.
