What size room are the Dynaudio Emit M30 and Polk S50 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
In the following sections, we will get into more detail in order to better understand how the Dynaudio Emit M30 and Polk S50 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Emit M30 features a 1.1" Tweeter and 2 x 6.6875" Magnesium Silicate Polymer Woofer . On the other hand, the S50 features a 1" Terylene Dome Tweeter and 2 x 5.25" Mica-reinforced polypropylene Woofer with a Crossover frequency at 2500Hz.
Frequency Response
Emit M30 has a frequency range of 40-23k Hz whereas S50 has a frequency range of 33-40k Hz. With a minimum frequency of 33Hz, the S50 can go significantly deeper on the low side and provide stronger bass compared to the Emit M30's min frequency of 40Hz.
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.

High Frequency
Floor-standing Speakers
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
Emit M30 is a 4 ohms speaker compared to the S50 which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Emit M30 can provide this impedance level.
These two speakers also have different sensitivity levels. Emit M30 sensitivity is rated at 86 dB and the S50's is rated at 89 dB. This 3 dB difference makes the Polk S50 a more sensitive speaker compared to Dynaudio Emit M30, 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.
Emit M30 can handle a max power of 200 watts RMS from the amp the whereas S50 has a max power handling value of 150 watts RMS, 50 watts less than the Emit M30.
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
S50 features 5-way post posts which make bi-amping or bi-wiring possible. Emit M30 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 Dynaudio Emit M30's and Polk S50's external dimensions. Dynaudio Emit M30 has external dimensions of 961.0 x 205.0 x 296.0mm ( 37-13/16 x 8-1/16 x 11-5/8inch) whereas Polk S50 has external dimensions of 951.0 x 262.0 x 281.0mm ( 37-7/16 x 10-5/16 x 11-1/16inch) .
Polk S50 is 10mm shorter and 15mm less deeper than Dynaudio Emit M30 but it is also 57mm 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 Dynaudio Emit M30 is approximately 606.8cm2 / 94.1inch2 and base area of the Polk S50 is approximately 736.2cm2 / 114.1inch2. The Emit M30 requires 18% less surface area than the S50 which gives it a small advantage on placement in tight spaces.
