In this review, we will be comparing M126Be and Diamond 225, two Passive Bookshelf speakers from Revel and Wharfedale. Let's have a brief look at the main features
of Revel M126Be and Wharfedale 225 first before getting into our more
detailed comparison.
What size room are the Revel M126Be and Wharfedale 225 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 Revel M126Be and Wharfedale 225 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

M126Be features a 1" beryllium Hard-Dome Tweeter and 1 x 6.5" DCC Aluminum Woofer . On the other hand, the Diamond 225 features a 1" Dome Tweeter and 1 x 6.5" Woven Kevlar Woofer with a Crossover frequency at 2300Hz.
Frequency Response
M126Be has a frequency range of 54-44k Hz whereas Diamond 225 has a frequency range of 45-20k Hz. With a minimum frequency of 45Hz, the Diamond 225 can go significantly deeper on the low side and provide stronger bass compared to 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 Diamond 225 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. M126Be sensitivity is rated at 86 dB and the Diamond 225's is at 87 dB. This 1 dB difference makes the Wharfedale 225 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.
M126Be can handle a max power of 150 watts RMS from the amp the whereas Diamond 225 has a max power handling value of 120 watts RMS, 30 watts less than the M126Be.
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
Diamond 225 features Post 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 Diamond 225 has a bottom firing ports. Wharfedale 225's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Revel M126Be with its rear-firing port.
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 Wharfedale 225'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 Wharfedale 225 has external dimensions of 355.0 x 196.0 x 290.0mm ( 13.9 x 7.7 x 11.4inch) .
Wharfedale 225 is 16mm narrower and 33mm shorter than Revel M126Be but it is also 28mm deeper.
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 Wharfedale 225 is approximately 568.4cm2 / 88.1inch2. The M126Be requires 2% less surface area than the Diamond 225 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 Wharfedale 225 weighs 6.55kg / 14.4lbs. This makes the M126Be 53% heavier than the Diamond 225.
Here is a comparison of how M126Be and Diamond 225's weights compare with the average, max and min weights in Passive Bookshelf class.
