What size room are the Emotiva Airmotiv XT1 and Klipsch R-620F 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:

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.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
One of the fundamental differences between these two speakers is that Airmotiv XT1 is a 3-way design whereas the R-620F 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.

Airmotiv XT1 features a 25×32 mm" folded ribbon Tweeter, a 4.5" Midrange and 3 x 5.25" woven fiber cone Woofer with a Crossover frequency at 410 Hz, 3.1 kHz. On the other hand, the R-620F features a 1.0" Tweeter and 2 x 6.5" Copper-spun IMG Woofer with a Crossover frequency at 2000Hz.
Frequency Response
Airmotiv XT1 has a frequency range of 45 Hz – 27 kHz whereas R-620F has a frequency range of 38-21k Hz. With a minimum frequency of 38Hz, the R-620F can go significantly deeper on the low side and provide stronger bass compared to the Airmotiv XT1's min frequency of 45Hz.
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
Airmotiv XT1 is a 4 ohms speaker compared to the R-620F which has a nominal impedance of 8 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 Airmotiv XT1 can provide this impedance level.
These two speakers also have different sensitivity levels. Airmotiv XT1 sensitivity is rated at 89 dB and the R-620F's is rated at 96 dB. This 7 dB difference makes the Klipsch R-620F a more sensitive speaker compared to Emotiva Airmotiv XT1, 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.
Airmotiv XT1 can handle a max power of 200 watts RMS, whereas R-620F has a max power handling value of 100 watts RMS, 100 watts less than the Airmotiv XT1.
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
Airmotiv XT1 features Binding post posts which make bi-amping or bi-wiring possible. R-620F has a Post which doesn't feature bi-amping/bi-wiring.
Emotiva Airmotiv XT1's Binding post terminals allows Bi-amping or bi-wiring
Klipsch R-620F's Post terminals
Cabinet Type and Port Position
Both Airmotiv XT1 and R-620F 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 Emotiva Airmotiv XT1's and Klipsch R-620F's external dimensions. Emotiva Airmotiv XT1 has external dimensions of 1060.0 x 222.0 x 254.0mm (41.75” x 7” x 10”) whereas Klipsch R-620F has external dimensions of 1021.0 x 239.0 x 369.0mm (40-3/16 x 9-3/8 x 14-1/2inch).
Emotiva Airmotiv XT1 is 17mm narrower and 115mm less deeper than Klipsch R-620F but it is also 39mm taller.
Below you can see the front view size comparison of Emotiva Airmotiv XT1 and Klipsch R-620F 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 Emotiva Airmotiv XT1 is approximately 563.9cm2 / 87.4inch2 and base area of the Klipsch R-620F is approximately 881.9cm2 / 136.7inch2. The Airmotiv XT1 requires 36% less surface area than the R-620F 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 Emotiva Airmotiv XT1 weighs 15.90kg / 35lbs and the Klipsch R-620F weighs 18.64kg / 41lbs. This makes the R-620F 17% heavier than the Airmotiv XT1.
Here is a comparison of how Airmotiv XT1 and R-620F's weights compare with the average, max and min weights in Passive Floor-standing class.

A generation apart: Emotiva Airmotiv XT1 is the newer design, against a 2018 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass | B | Klipsch R-620F digs deeper - 38Hz against 45Hz. A subwoofer would even that out. |
| Amplifier needs | B | Klipsch R-620F is more sensitive (96dB vs 89dB), so it goes louder on the same amplifier. |
| Amplifier match | B | Klipsch R-620F is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | A | Emotiva Airmotiv XT1 takes more power (200W vs 100W) - more in hand in a big room. |
| Size | depends | Emotiva Airmotiv XT1 is easier to place; Klipsch R-620F is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | A | Emotiva Airmotiv XT1: bi-amping. Emotiva Airmotiv XT1 sits in a wider range (10 models), so a matched surround system is easier later. |
| Price | evenly matched | Much the same money ($999 vs $998 a pair). |
A Emotiva Airmotiv XT1 B Klipsch R-620F
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 R-620F has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 45Hz anyway, so judge these on the other rows instead. Match it to your room: we rate Emotiva Airmotiv XT1 the better fit for a large room and a very large room, and Klipsch R-620F for a small room and 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.
