In this review, we will be comparing Emit M30 and RTi A5, two Passive Floor-standing speakers from Dynaudio and Polk Audio. Let's have a brief look at the main features
of Dynaudio Emit M30 and Polk RTi A5 first before getting into our more
detailed comparison.
What size room are the Dynaudio Emit M30 and Polk RTi A5 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:
In the following sections, we will get into more detail in order to better understand how the Dynaudio Emit M30 and Polk RTi A5 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 RTi A5 features a 1" Tweeter and 2 x 6.5" Polymer composite Woofer .
Frequency Response
Emit M30 has a frequency range of 40-23k Hz whereas RTi A5 has a frequency range of 40-26k Hz.
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 RTi A5 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 RTi A5's is rated at 90 dB. This 4 dB difference makes the Polk RTi A5 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 250 watts RMS from the amp the whereas Emit M30 has a max power handling value of 200 watts RMS , 50 watts less than the RTi A5.
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
RTi A5 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 RTi A5'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 RTi A5 has external dimensions of 1007.0 x 269.0 x 404.0mm ( 39-5/8 x 10-9/16 x 15-7/8inch) .
Polk RTi A5 is clearly the larger of the two speakers. Its body is 64mm wider, 46mm taller and 108mm deeper than Dynaudio Emit M30.
Below you can see the front view size comparison of Dynaudio Emit M30 and Polk RTi A5 in scale.
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 RTi A5 is approximately 1086.8cm2 / 168.5inch2. The Emit M30 requires 44% less surface area than the RTi A5 which gives it a small advantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Dynaudio Emit M30 weighs 18.18kg / 40lbs and the Polk RTi A5 weighs 18.18kg / 40lbs.
Here is a comparison of how Emit M30 and RTi A5's weights compare with the average, max and min weights in Passive Floor-standing class.
