A170 features a 1" aluminum HDI (High Definition Imaging) waveguide Tweeter and 2 x 5.25" Polycellulose Woofer . On the other hand, the S 807 features a 1" Tweeter and 2 x 5" Aluminized Polyfiber Woofer with a Crossover frequency at 2000Hz.
Frequency Response
A170 has a frequency range of 44-40k Hz whereas S 807 has a frequency range of 42-26k Hz. With a minimum frequency of 42Hz, the S 807 can go slightly deeper then the A170's min frequency of 44Hz.
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
A170 is a 6 ohms speaker compared to the S 807 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. A170 sensitivity is rated at 89 dB and the S 807's is rated at 90 dB. This 1 dB difference makes the Jamo S 807 a more sensitive speaker compared to JBL Stage A170, 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.
A170 can handle a max power of 200 watts RMS from the amp the whereas S 807 has a max power handling value of 100 watts RMS, 100 watts less than the A170.
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
A170 features 5-Way post posts which make bi-amping or bi-wiring possible. S 807 has a Binding post which doesn't feature bi-amping/bi-wiring.

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 JBL Stage A170's and Jamo S 807's external dimensions. JBL Stage A170 has external dimensions of 977.0 x 267.0 x 331.0mm ( 38-7/16 x 10-1/2 x 13inch) whereas Jamo S 807 has external dimensions of 915.0 x 191.0 x 252.0mm ( 36-1/2 x 10-1/8 x 10-9/16inch) .
JBL Stage A170 is clearly the larger of the two speakers. Its body is 76mm wider, 62mm taller and 79mm deeper than Jamo S 807.
Below you can see the front view size comparison of JBL Stage A170 and Jamo S 807 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 JBL Stage A170 is approximately 883.8cm2 / 137.0inch2 and base area of the Jamo S 807 is approximately 481.3cm2 / 74.6inch2. The A170 requires 84% more surface area than the S 807 which gives it a small disadvantage on placement in tight spaces.
