A170 features a 1" aluminum HDI (High Definition Imaging) waveguide Tweeter and 2 x 5.25" Polycellulose Woofer . On the other hand, the A135C features a 1" aluminum dome with HDI (High Definition Imaging) waveguide technology Tweeter and 6 x 3" polycellulose Woofer .
Frequency Response
A170 has a frequency range of 44-40k Hz whereas A135C has a frequency range of 75-40k Hz. With a minimum frequency of 44Hz, the A170 can go significantly deeper on the low side and provide stronger bass compared to the A135C's min frequency of 75Hz.
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 and A135C have the same Impedance of 6 ohms but where they differ is the sensitivity levels. A170 sensitivity is rated at 89 dB and the A135C's is at 90 dB. This 1 dB difference makes the JBL Stage A135C 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 A135C has a max power handling value of 150 watts RMS, 50 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. A135C has a 5-way 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 JBL Stage A135C'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 JBL Stage A135C has external dimensions of 105.0 x 747.0 x 186.0mm ( 4-1/8 x 29-3/8 x 7-5/16inch) .
JBL Stage A135C is 872mm shorter and 145mm less deeper than JBL Stage A170 but it is also 480mm wider.
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 JBL Stage A135C is approximately 1389.4cm2 / 215.4inch2. The A170 requires 36% less surface area than the A135C which gives it a small advantage on placement in tight spaces.
