What size room are the Emotiva Airmotiv T2+ and Klipsch RP-280F 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 T2+ is a 3-way design whereas the RP-280F 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 T2+ features a 25×32 mm" folded ribbon Tweeter, a 5.25" Midrange and 2 x 8" woven fiber cone Woofer with a Crossover frequency at 350 Hz and 3200Hz. On the other hand, the RP-280F features a 1" Tractrix Horn Tweeter and 2 x 8" Cerametallic Woofer with a Crossover frequency at 1750 Hz.
Frequency Response
Airmotiv T2+ has a frequency range of 35 Hz – 28 kHz whereas RP-280F has a frequency range of 32-25k Hz. With a minimum frequency of 32Hz, the RP-280F can go slightly deeper then the Airmotiv T2+'s min frequency of 35Hz.
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 T2+ is a 4 ohms speaker compared to the RP-280F 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 T2+ can provide this impedance level.
These two speakers also have different sensitivity levels. Airmotiv T2+ sensitivity is rated at 91 dB and the RP-280F's is rated at 98 dB. This 7 dB difference makes the Klipsch RP-280F a more sensitive speaker compared to Emotiva Airmotiv T2+, 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 T2+ can handle a max power of 200 watts RMS, whereas RP-280F has a max power handling value of 150 watts RMS, 50 watts less than the Airmotiv T2+.
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
Both Airmotiv T2+ and RP-280F features dual binding post speaker terminals for bi-amping or bi-wiring.
Emotiva Airmotiv T2+'s Binding post terminals allows Bi-amping or bi-wiring
Klipsch RP-280F's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Airmotiv T2+ and RP-280F 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 T2+'s and Klipsch RP-280F's external dimensions. Emotiva Airmotiv T2+ has external dimensions of 1085.0 x 310.0 x 439.0mm (42-11/16 x 12-3/16 x 17-1/4inch) whereas Klipsch RP-280F has external dimensions of 1094.0 x 269.0 x 442.0mm (43-1/16 x 10-9/16 x 17-3/8inch).
Emotiva Airmotiv T2+ is 9mm shorter and 3mm less deeper than Klipsch RP-280F but it is also 41mm 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 Emotiva Airmotiv T2+ is approximately 1360.9cm2 / 210.9inch2 and base area of the Klipsch RP-280F is approximately 1189.0cm2 / 184.3inch2. The Airmotiv T2+ requires 14% more surface area than the RP-280F which gives it a small disadvantage 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 T2+ weighs 25.90kg / 57lbs and the Klipsch RP-280F weighs 28.41kg / 62.5lbs. This makes the RP-280F 10% heavier than the Airmotiv T2+.
Here is a comparison of how Airmotiv T2+ and RP-280F's weights compare with the average, max and min weights in Passive Floor-standing class.

A generation apart: Emotiva Airmotiv T2+ is the newer design, against a 2015 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 RP-280F digs deeper - 32Hz against 35Hz. A subwoofer would even that out. |
| Amplifier needs | B | Klipsch RP-280F is more sensitive (98dB vs 91dB), so it goes louder on the same amplifier. |
| Amplifier match | B | Klipsch RP-280F is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | A | Emotiva Airmotiv T2+ takes more power (200W vs 150W) - more in hand in a big room. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | Emotiva Airmotiv T2+: bi-amping; Klipsch RP-280F: bi-amping. Klipsch RP-280F sits in a wider range (17 models), so a matched surround system is easier later. |
| Price | evenly matched | Much the same money ($1,099 vs $1,198 a pair). |
A Emotiva Airmotiv T2+ B Klipsch RP-280F
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-280F 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 your amplifier is modest, vintage or valve-based, Klipsch RP-280F is the safer partner - the other will want more current or more watts to sound its best.
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.
