ES35 features a 1" Terylene High-res dome Tweeter and 6 x 3" mica-reinforced polypropylene Dynamic Balance Woofer. On the other hand, the ES50 features a 1" Terylene High-Res Soft-Dome Tweeter and 2 x 5.25" Mica-reinforced polypropylene Woofer with a Crossover frequency at 2500Hz.
Frequency Response
ES35 has a frequency range of 66-40k Hz whereas ES50 has a frequency range of 38-40k Hz. With a minimum frequency of 38Hz, the ES50 can go significantly deeper on the low side and provide stronger bass compared to the ES35's min frequency of 66Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Center Channel class in our database.
Low Frequency
Center Channel Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
ES35 and ES50 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. ES35 sensitivity is rated at 89 dB and the ES50's is at 88 dB. This 1 dB difference makes the Polk ES35 a more sensitive speaker compared to Polk ES50, 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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
ES50 can handle a max power of 200 watts RMS, whereas ES35 has a max power handling value of 150 watts RMS, 50 watts less than the ES50.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
ES50 features 5-Way post posts which make bi-amping or bi-wiring possible. ES35 has a 5-Way post which doesn't feature bi-amping/bi-wiring.

Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Polk ES35's and Polk ES50's external dimensions. Polk ES35 has external dimensions of 107.0 x 621.0 x 154.0mm (4-3/16 x 24-7/16 x 6-1/16inch) whereas Polk ES50 has external dimensions of 951.0 x 191.0 x 281.0mm (37-7/16 x 7-1/2 x 11-1/16inch).
Polk ES35 is 844mm shorter and 127mm less deeper than Polk ES50 but it is also 430mm 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 Polk ES35 is approximately 956.3cm2 / 148.2inch2 and base area of the Polk ES50 is approximately 536.7cm2 / 83.2inch2. The ES35 requires 78% more surface area than the ES50 which gives it a small disadvantage on placement in tight spaces.
