In this review, we will be comparing Airmotiv T2+ and R700, two Passive Floor-standing speakers from Emotiva and Polk Audio. Let's have a brief look at the main features
of Emotiva Airmotiv T2+ and Polk R700 first before getting into our more
detailed comparison.
What size room are the Emotiva Airmotiv T2+ and Polk R700 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:

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.
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.

High Frequency

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 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.

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.
Airmotiv T2+ can handle a max power of 300 watts RMS from the amp the whereas Airmotiv T2+ has a max power handling value of 200 watts RMS , 100 watts less than the R700.
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
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
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 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.
