Stage 250WL features a 1" Horn-Loaded Tweeter and 2 x 5.25" Polycellulose Woofer . On the other hand, the A170 features a 1" aluminum HDI (High Definition Imaging) waveguide Tweeter and 2 x 5.25" Polycellulose Woofer .
Frequency Response
Stage 250WL has a frequency range of 52-25kHz whereas A170 has a frequency range of 44-40k Hz. With a minimum frequency of 44Hz, the A170 can go significantly deeper on the low side and provide stronger bass compared to the Stage 250WL's min frequency of 52Hz.
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 In-wall 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
Stage 250WL is a 8 ohms speaker compared to the A170 which has a nominal impedance of 6 ohms.
These two speakers also have different sensitivity levels. Stage 250WL sensitivity is rated at 90 dB and the A170's is rated at 89 dB. This 1 dB difference makes the JBL Stage 250WL 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.
Stage 250WL can handle a max power of 200 watts RMS from the amp the whereas Stage 250WL has a max power handling value of 120 watts RMS , 80 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. Stage 250WL has a Spring 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 250WL's and JBL Stage A170's external dimensions. JBL Stage 250WL has external dimensions of 461.0 x 162.0 x 97.0mm ( 18.1250-inch x 6.3750-inch x 3.8125-inch) whereas JBL Stage A170 has external dimensions of 977.0 x 267.0 x 331.0mm ( 38-7/16 x 10-1/2 x 13inch) .
JBL Stage A170 is clearly the larger of the two speakers. Its body is 105mm wider, 516mm taller and 234mm deeper than JBL Stage 250WL.
