What size room are the Monitor Audio Studio 89 and Wharfedale EVO5.2 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.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
One of the fundamental differences between these two speakers is that Studio 89 is a 2-way design whereas the EVO5.2 is a 3-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.

Studio 89 features a " MPD III (folded ribbon) Tweeter and 2 x 4.25" RDT III Woofer with a Crossover frequency at 2400Hz. On the other hand, the 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.
Frequency Response
Studio 89 has a frequency range of 48-60k Hz whereas EVO5.2 has a frequency range of 44-24k Hz. With a minimum frequency of 44Hz, the EVO5.2 can go slightly deeper then the Studio 89's min frequency of 48Hz.
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
Studio 89 is a 6 ohms speaker compared to the EVO5.2 which has a nominal impedance of 4 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. Studio 89 sensitivity is rated at 86 dB and the EVO5.2's is rated at 88 dB. This 2 dB difference makes the Wharfedale EVO5.2 a more sensitive speaker compared to Monitor Audio Studio 89, hence will play louder with the same amount of watts.
Sensitivity
Bookshelf Speakers
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.
Studio 89 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 Studio 89.
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.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Studio 89 features Binding post type posts and EVO5.2 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Studio 89 has a rear firing port whereas EVO5.2 has a bottom firing ports. Wharfedale EVO5.2's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Monitor Audio Studio 89 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 Monitor Audio Studio 89's and Wharfedale EVO5.2's external dimensions. Monitor Audio Studio 89 has external dimensions of 340.0 x 157.0 x 361.0mm (13-3/8 x 6-3/16 x 14-3/16inch) whereas Wharfedale EVO5.2 has external dimensions of 497.0 x 260.0 x 391.0mm (19.6" × 10.2" × 15.4").
Wharfedale EVO5.2 is clearly the larger of the two speakers. Its body is 103mm wider, 157mm taller and 30mm deeper than Monitor Audio Studio 89.
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 Monitor Audio Studio 89 is approximately 566.8cm2 / 87.9inch2 and base area of the Wharfedale EVO5.2 is approximately 1016.6cm2 / 157.6inch2. The Studio 89 requires 44% less surface area than the EVO5.2 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 Monitor Audio Studio 89 weighs 7.60kg / 16.7lbs and the Wharfedale EVO5.2 weighs 15.05kg / 33.1lbs. This makes the EVO5.2 98% heavier than the Studio 89.
Here is a comparison of how Studio 89 and EVO5.2's weights compare with the average, max and min weights in Passive Bookshelf class.

No single best speaker here - they are built to different priorities, and the right one depends on your room, your amplifier and what you listen to.
| Area | Better | Why |
|---|
| Bass | B | Wharfedale EVO5.2 digs deeper - 44Hz against 48Hz. A subwoofer would even that out. |
| Amplifier needs | B | Wharfedale EVO5.2 is more sensitive (88dB vs 86dB), so it goes louder on the same amplifier. |
| Amplifier match | A | Monitor Audio Studio 89 is the easier load at 6 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | A | Monitor Audio Studio 89 takes more power (150W vs 120W) - more in hand in a big room. |
| Size | depends | Monitor Audio Studio 89 is easier to place; Wharfedale EVO5.2 is bigger, which usually goes with fuller bass. Your room decides. |
| Price | B | Wharfedale EVO5.2 is cheaper - $1,799 against $2,500, about 28% less. |
A Monitor Audio Studio 89 B Wharfedale EVO5.2
depends neither is better in the abstract - it turns on your room, your system 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?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. Match it to your room: we rate Monitor Audio Studio 89 the better fit for near-field listening and a small room, and Wharfedale EVO5.2 for a mid-size room and a large room. 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, Monitor Audio Studio 89 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.
