Airmotiv B1+ features a 25×32 mm" folded ribbon Tweeter and 1 x 5.25" woven fiber cone Woofer with a Crossover frequency at 2000Hz. On the other hand, the S 801 features a 1" Soft-Dome Tweeter and 1 x 4" Aluminized Polyfiber Woofer .
Frequency Response
Airmotiv B1+ has a frequency range of 48 Hz – 28 kHz whereas S 801 has a frequency range of 76-26k Hz. With a minimum frequency of 48Hz, the Airmotiv B1+ can go significantly deeper on the low side and provide stronger bass compared to the S 801's min frequency of 76Hz.
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 Bookshelf 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 B1+ and S 801 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Airmotiv B1+ sensitivity is rated at 86 dB and the S 801's is at 85 dB. This 1 dB difference makes the Emotiva Airmotiv B1+ a more sensitive speaker compared to Jamo S 801, 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 B1+ can handle a max power of 70 watts RMS from the amp the whereas S 801 has a max power handling value of 60 watts RMS, 10 watts less than the Airmotiv B1+.
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.
Cabinet Type and Port Position
Both Airmotiv B1+ and S 801 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 B1+'s and Jamo S 801's external dimensions. Emotiva Airmotiv B1+ has external dimensions of 274.0 x 181.0 x 210.0mm ( 10-3/4 x 7-1/8 x 8-1/4inch) whereas Jamo S 801 has external dimensions of 285.0 x 156.0 x 163.0mm ( 11.2 x 6.1 x 6.4inch) .
Jamo S 801 is 25mm narrower and 47mm less deeper than Emotiva Airmotiv B1+ but it is also 11mm taller.
Below you can see the front view size comparison of Emotiva Airmotiv B1+ and Jamo S 801 in scale.

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 B1+ is approximately 380.1cm2 / 58.9inch2 and base area of the Jamo S 801 is approximately 254.3cm2 / 39.4inch2. The Airmotiv B1+ requires 49% more surface area than the S 801 which gives it a small disadvantage on placement in tight spaces.
