In this review, we will be comparing Airmotiv T1+ and R-820F, two Passive Floor-standing speakers from Emotiva and Klipsch. Let's have a brief look at the main features
of Emotiva Airmotiv T1+ and Klipsch R-820F first before getting into our more
detailed comparison.
What size room are the Emotiva Airmotiv T1+ and Klipsch R-820F 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:
In the following sections, we will get into more detail in order to better understand how the Emotiva Airmotiv T1+ and Klipsch R-820F compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that Airmotiv T1+ is a 3-way design whereas the R-820F 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 T1+ features a 25×32 mm" folded ribbon Tweeter , a 5.25" Midrange and 2 x 6" woven fiber cone Woofer with a Crossover frequency at 275 Hz and 2700Hz. On the other hand, the R-820F features a 1" Tweeter and 2 x 8" Copper-spun IMG Woofer .
Frequency Response
Airmotiv T1+ has a frequency range of 37 Hz – 28 kHz whereas R-820F has a frequency range of 35-21k Hz. With a minimum frequency of 35Hz, the R-820F can go slightly deeper then the Airmotiv T1+'s min frequency of 37Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Floor-standing class in our database.

None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Airmotiv T1+ is a 4 ohms speaker compared to the R-820F 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 T1+ can provide this impedance level.
These two speakers also have different sensitivity levels. Airmotiv T1+ sensitivity is rated at 88 dB and the R-820F's is rated at 97 dB. This 9 dB difference makes the Klipsch R-820F a more sensitive speaker compared to Emotiva Airmotiv T1+, hence will play louder with the same amount of watts.

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
Airmotiv T1+ features Binding post posts which make bi-amping or bi-wiring possible. R-820F has a Post which doesn't feature bi-amping/bi-wiring.

Physical Specs
Size of a speaker can sometimes become 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 T1+'s and Klipsch R-820F's external dimensions. Emotiva Airmotiv T1+ has external dimensions of 1004.0 x 213.0 x 296.0mm ( 39-1/2 x 8-3/8 x 11-5/8inch) whereas Klipsch R-820F has external dimensions of 1096.0 x 277.0 x 426.0mm ( 43-1/8 x 10-7/8 x 16-3/4inch) .
Klipsch R-820F is clearly the larger of the two speakers. Its body is 64mm wider, 92mm taller and 130mm deeper than Emotiva Airmotiv T1+.
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 T1+ is approximately 630.5cm2 / 97.7inch2 and base area of the Klipsch R-820F is approximately 1180.0cm2 / 182.9inch2. The Airmotiv T1+ requires 47% less surface area than the R-820F 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 T1+ weighs 18.20kg / 40lbs and the Klipsch R-820F weighs 24.55kg / 54lbs. This makes the R-820F 35% heavier than the Airmotiv T1+.
Here is a comparison of how Airmotiv T1+ and R-820F's weights compare with the average, max and min weights in Passive Floor-standing class.
