What size room are the Focal Kanta No.1 and Klipsch RP-400M 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:

position, speaker locations, etc.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
Both Kanta No.1 and RP-400M are 2-way speakers.

Kanta No.1 features a 1.1" Hard-Dome Tweeter and 1 x 6.5" Flax Woofer with a Crossover frequency at 2400 Hz. On the other hand, the RP-400M features a 1" Tractrix Horn Tweeter and 1 x 4" Cerametallic Woofer with a Crossover frequency at 1500Hz.
Frequency Response
Kanta No.1 has a frequency range of 46-40k Hz whereas RP-400M has a frequency range of 52-25k Hz. With a minimum frequency of 46Hz, the Kanta No.1 can go significantly deeper on the low side and provide stronger bass compared to the RP-400M's min frequency of 52Hz.
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
Kanta No.1 and RP-400M have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Kanta No.1 sensitivity is rated at 88 dB and the RP-400M's is at 93 dB. This 5 dB difference makes the Klipsch RP-400M a more sensitive speaker compared to Focal Kanta No.1, hence will play louder with the same amount of watts.
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.
Kanta No.1 can handle a max power of 150 watts RMS, whereas RP-400M has a max power handling value of 50 watts RMS, 100 watts less than the Kanta No.1.
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
Kanta No.1 features Single binding posts type posts and RP-400M has a Single binding posts type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Kanta No.1 and RP-400M 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 Kanta No.1's and Klipsch RP-400M's external dimensions. Focal Kanta No.1 has external dimensions of 609.6 x 228.6 x 393.0mm (24-28inch x 9-1/4inch x 15-7/16inch) whereas Klipsch RP-400M has external dimensions of 298.0 x 144.0 x 191.0mm (11.7 x 5.6 x 7.5inch).
Focal Kanta No.1 is clearly the larger of the two speakers. Its body is 84.6mm wider, 311.6mm taller and 202mm deeper than Klipsch RP-400M.
Below you can see the front view size comparison of Focal Kanta No.1 and Klipsch RP-400M in scale.

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 Kanta No.1 is approximately 898.4cm2 / 139.3inch2 and base area of the Klipsch RP-400M is approximately 275.0cm2 / 42.6inch2. The Kanta No.1 requires 227% more surface area than the RP-400M which gives it a small disadvantage on placement in tight spaces.
Here is another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

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 Kanta No.1 weighs 13.05kg / 28.7lbs and the Klipsch RP-400M weighs 4.10kg / 9lbs. This makes the Kanta No.1 218% heavier than the RP-400M.

These sit in different price classes - Focal Kanta No.1 costs roughly 20x what Klipsch RP-400M 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 | A | Focal Kanta No.1 digs deeper - 46Hz against 52Hz. A subwoofer would even that out. |
| Amplifier needs | B | Klipsch RP-400M is more sensitive (93dB vs 88dB), so it goes louder on the same amplifier. |
| Headroom | A | Focal Kanta No.1 takes more power (150W vs 50W) - more in hand in a big room. |
| Size | depends | Klipsch RP-400M is easier to place; Focal Kanta No.1 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Neither adds bi-amping, a sub output or height drivers. Klipsch RP-400M sits in a wider range (17 models), so a matched surround system is easier later. |
| Price | B | Klipsch RP-400M is cheaper - $399 against $7,998, about 95% less; arguably a different class. |
A Focal Kanta No.1 B Klipsch RP-400M
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?
Focal Kanta No.1 is ahead, but only on 1 of the measured areas, and it costs about 20x the price. That is a lot of money for a narrow margin on paper - Klipsch RP-400M looks like the sensible buy unless something else about the Focal Kanta No.1 appeals to you. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 52Hz anyway, which makes the cheaper Klipsch RP-400M much easier to justify. Match it to your room: we rate Focal Kanta No.1 the better fit for a mid-size room and a large room, and Klipsch RP-400M for near-field listening and a small 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.
