M126Be features a 1" beryllium Hard-Dome Tweeter and 1 x 6.5" DCC Aluminum Woofer . On the other hand, the RTi A3 features a 1" silk polymer composite Dome Tweeter and 1 x 6.5" Polymer composite Woofer with a Crossover frequency at 2800Hz.
Frequency Response
M126Be has a frequency range of 54-44k Hz whereas RTi A3 has a frequency range of 50-26k Hz. With a minimum frequency of 50Hz, the RTi A3 can go slightly deeper then the M126Be's min frequency of 54Hz.
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.

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
M126Be and RTi A3 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. M126Be sensitivity is rated at 86 dB and the RTi A3's is at 89 dB. This 3 dB difference makes the Polk RTi A3 a more sensitive speaker compared to Revel M126Be, 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.
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 A3 features Pair of Dual 5-way Binding Posts - Gold-Plated posts which make bi-amping or bi-wiring possible. M126Be has a Binding post which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
M126Be has a rear firing port whereas RTi A3 has a back and front firing ports.
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 Revel M126Be's and Polk RTi A3's external dimensions. Revel M126Be has external dimensions of 388.0 x 212.0 x 262.0mm ( 15-1/4 x 8-5/16 x 10-5/16inch) whereas Polk RTi A3 has external dimensions of 374.7 x 214.4 x 355.6mm ( 14.7 x 8.4 x 14.0inch) .
Revel M126Be is 2.4mm narrower and 93.6mm less deeper than Polk RTi A3 but it is also 13.3mm 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 Revel M126Be is approximately 555.4cm2 / 86.1inch2 and base area of the Polk RTi A3 is approximately 762.4cm2 / 118.2inch2. The M126Be requires 27% less surface area than the RTi A3 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 Revel M126Be weighs 10.00kg / 22lbs and the Polk RTi A3 weighs 7.26kg / 16lbs. This makes the M126Be 38% heavier than the RTi A3.
Here is a comparison of how M126Be and RTi A3's weights compare with the average, max and min weights in Passive Bookshelf class.
