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 R700 features a 1" Pinnacle Ring Radiator Tweeter, a 6.5" Midrange and 2 x 8" Polypropylene Woofer with a Crossover frequency at 350Hz and 2700Hz.
Frequency Response
Airmotiv T2+ has a frequency range of 35 Hz – 28 kHz whereas R700 has a frequency range of 38-38k Hz. With a minimum frequency of 35Hz, the Airmotiv T2+ can go slightly deeper then the R700's min frequency of 38Hz.
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 R700 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 R700's is rated at 88 dB. This 3 dB difference makes the Emotiva Airmotiv T2+ a more sensitive speaker compared to Polk R700, 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.
R700 can handle a max power of 300 watts RMS, whereas Airmotiv T2+ has a max power handling value of 200 watts RMS, 100 watts less than the R700.
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 R700 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
Polk R700's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Airmotiv T2+ has a rear firing port whereas R700 has a bottom firing ports. Polk R700's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Emotiva Airmotiv T2+ with its rear-firing port.

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 Polk R700'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 Polk R700 has external dimensions of 1143.8 x 320.7 x 428.3mm (45 x 12.6 x 16.9inch).
Emotiva Airmotiv T2+ is 10.7mm narrower and 58.8mm shorter than Polk R700 but it is also 10.7mm deeper.
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 Polk R700 is approximately 1373.6cm2 / 212.9inch2. The Airmotiv T2+ requires 1% less surface area than the R700 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 T2+ weighs 25.90kg / 57lbs and the Polk R700 weighs 35.90kg / 79lbs. This makes the R700 39% heavier than the Airmotiv T2+.
Here is a comparison of how Airmotiv T2+ and R700's weights compare with the average, max and min weights in Passive Floor-standing class.

These sit in different price classes - Polk R700 costs roughly 2x what Emotiva Airmotiv T2+ 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 | Emotiva Airmotiv T2+ digs deeper - 35Hz against 38Hz. A subwoofer would even that out. |
| Amplifier needs | A | Emotiva Airmotiv T2+ is more sensitive (91dB vs 88dB), so it goes louder on the same amplifier. |
| Amplifier match | B | Polk R700 is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | B | Polk R700 takes more power (300W vs 200W) - more in hand in a big room. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | Emotiva Airmotiv T2+: bi-amping; Polk R700: bi-amping. |
| Price | A | Emotiva Airmotiv T2+ is cheaper - $1,099 against $2,198, about 50% less; arguably a different class. |
A Emotiva Airmotiv T2+ B Polk R700
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?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. Match it to your room: we rate Emotiva Airmotiv T2+ the better fit for a mid-size room, and Polk R700 for a very large room. If your amplifier is modest, vintage or valve-based, Emotiva Airmotiv T2+ 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.
