ES10 features a 1" Terylene Soft-Dome Tweeter and 1 x 4" Mica-reinforced polypropylene Woofer with a Crossover frequency at 2500Hz. On the other hand, the ES30 features a 1" Terylene High-res dome Tweeter and 2 x 5.5" mica-reinforced polypropylene Dynamic Balance Woofer .
Frequency Response
ES10 has a frequency range of 78-40k Hz whereas ES30 has a frequency range of 55-40k Hz. With a minimum frequency of 55Hz, the ES30 can go significantly deeper on the low side and provide stronger bass compared to the ES10's min frequency of 78Hz.
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.

High Frequency

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
ES10 and ES30 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. ES10 sensitivity is rated at 84 dB and the ES30's is at 89 dB. This 5 dB difference makes the Polk ES30 a more sensitive speaker compared to Polk ES10, 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.
ES10 can handle a max power of 125 watts RMS from the amp the whereas ES10 has a max power handling value of 100 watts RMS , 25 watts less than the ES30.
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
ES10 features 5-Way post type posts and ES30 has a 5-Way post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both ES10 and ES30 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 Polk ES10's and Polk ES30's external dimensions. Polk ES10 has external dimensions of 215.0 x 139.0 x 158.0mm ( 8-7/16 x 5-7/16 x 6-3/16inch) whereas Polk ES30 has external dimensions of 191.0 x 510.0 x 270.0mm ( 7-1/2 x 20-1/16 x 10-5/8inch) .
Polk ES10 is 371mm narrower and 112mm less deeper than Polk ES30 but it is also 24mm taller.
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 ES10 is approximately 219.6cm2 / 34.0inch2 and base area of the Polk ES30 is approximately 1377.0cm2 / 213.4inch2. The ES10 requires 84% less surface area than the ES30 which gives it a small advantage on placement in tight spaces.
