What size room are the Wharfedale EVO5.2 and Revel M106 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

Drivers
One of the fundamental differences between these two speakers is that EVO5.2 is a 3-way design whereas the M106 is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

EVO5.2 features a 1.375" SilentWeave cotton and felt damping fiber AMT (Ribbon) Tweeter, a 2" Midrange and 1 x 6.5" woven Kevlar Woofer with a Crossover frequency at 800 Hz and 4.3 kHz. On the other hand, the M106 features a 1" aluminum Hard-Dome with Acoustic Lens Waveguide Tweeter and 1 x 6.5" Aluminum Woofer with a Crossover frequency at 2300Hz.
Frequency Response
EVO5.2 has a frequency range of 44-24k Hz whereas M106 has a frequency range of 59Hz- 20kHz. With a minimum frequency of 44Hz, the EVO5.2 can go significantly deeper on the low side and provide stronger bass compared to the M106's min frequency of 59Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
EVO5.2 is a 4 ohms speaker compared to the M106 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 EVO5.2 can provide this impedance level.
These two speakers also have different sensitivity levels. EVO5.2 sensitivity is rated at 88 dB and the M106's is rated at 87 dB. This 1 dB difference makes the Wharfedale EVO5.2 a more sensitive speaker compared to Revel M106, 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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
M106 can handle a max power of 150 watts RMS, whereas EVO5.2 has a max power handling value of 120 watts RMS, 30 watts less than the M106.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.

considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
EVO5.2 features Binding post type posts and M106 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Revel M106's Binding post terminals
Cabinet Type and Port Position
EVO5.2 has a bottom firing port whereas M106 has a rear firing ports. Wharfedale EVO5.2's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Revel M106 with its rear-firing port.
Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Wharfedale EVO5.2's and Revel M106's external dimensions. Wharfedale EVO5.2 has external dimensions of 497.0 x 260.0 x 350.0mm (19.6" × 10.2" × 15.4") whereas Revel M106 has external dimensions of 383.0 x 210.0 x 280.0mm (15-1/16 x 8-1/4 x 11inch).
Wharfedale EVO5.2 is clearly the larger of the two speakers. Its body is 50mm wider, 114mm taller and 70mm deeper than Revel M106.
Below you can see the front view size comparison of Wharfedale EVO5.2 and Revel M106 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 Wharfedale EVO5.2 is approximately 910.0cm2 / 141.1inch2 and base area of the Revel M106 is approximately 588.0cm2 / 91.1inch2. The EVO5.2 requires 55% more surface area than the M106 which gives it a small disadvantage 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 Wharfedale EVO5.2 weighs 15.05kg / 33.1lbs and the Revel M106 weighs 8.41kg / 18.5lbs. This makes the EVO5.2 79% heavier than the M106.

These sit in different price classes - Revel M106 costs roughly 1.7x what Wharfedale EVO5.2 does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass |
A |
Wharfedale EVO5.2 digs deeper - 44Hz against 59Hz. |
| Amplifier needs |
evenly matched |
Similar sensitivity (88dB vs 87dB) - both want much the same power. |
| Amplifier match |
B |
Revel M106 is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom |
B |
Revel M106 takes more power (150W vs 120W) - more in hand in a big room. |
| Size |
depends |
Revel M106 is easier to place; Wharfedale EVO5.2 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability |
depends |
Neither adds bi-amping, a sub output or height drivers. Revel M106 sits in a wider range (8 models), so a matched surround system is easier later. |
| Price |
A |
Wharfedale EVO5.2 is cheaper - $1,299 against $2,200, about 41% less; arguably a different class. |
A Wharfedale EVO5.2
B Revel M106
depends neither is better in the abstract - it turns on your room, placement or how you will use them.
Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
Revel M106 is ahead, but only on 1 of the measured areas, and it costs about 41% more. That is a lot of money for a narrow margin on paper - Wharfedale EVO5.2 looks like the sensible buy unless something else about the Revel M106 appeals to you. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 59Hz anyway, so judge these on the other rows instead. In a large or open-plan room, Wharfedale EVO5.2 has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Revel M106 is the easier speaker to get right.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
