In this review, we will be comparing Airmotiv T2+ and BW 603, two Passive Floor-standing speakers from Emotiva and Bowers Wilkins. Let's have a brief look at the main features
of Emotiva Airmotiv T2+ and B&W 603 first before getting into our more
detailed comparison.
What size room are the Emotiva Airmotiv T2+ and B&W 603 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 T2+ and B&W 603 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

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 BW 603 features a 1" Tweeter , a 6" Midrange and 2 x 6.5" Paper Woofer .
Frequency Response
Airmotiv T2+ has a frequency range of 35 Hz – 28 kHz whereas BW 603 has a frequency range of 48-28k Hz. With a minimum frequency of 35Hz, the Airmotiv T2+ can go significantly deeper on the low side and provide stronger bass compared to the BW 603's min frequency of 48Hz.
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 T2+ is a 4 ohms speaker compared to the BW 603 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 BW 603's is rated at 88.5 dB. This 2 dB difference makes the Emotiva Airmotiv T2+ a more sensitive speaker compared to B&W 603, 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
Both Airmotiv T2+ and BW 603 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
Cabinet Type and Port Position
Both Airmotiv T2+ and BW 603 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
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 B&W 603'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 B&W 603 has external dimensions of 985.0 x 190.0 x 340.0mm ( 38.7 x 7.4 x 13.3inch) .
Emotiva Airmotiv T2+ is clearly the larger of the two speakers. Its body is 120mm wider, 100mm taller and 99mm deeper than B&W 603.
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 B&W 603 is approximately 646.0cm2 / 100.1inch2. The Airmotiv T2+ requires 111% more surface area than the BW 603 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 B&W 603 weighs 24.14kg / 53.1lbs. This makes the Airmotiv T2+ 7% heavier than the BW 603.
Here is a comparison of how Airmotiv T2+ and BW 603's weights compare with the average, max and min weights in Passive Floor-standing class.
