What size room are the Wharfedale EVO4.2 and Polk TSi200 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 EVO4.2 is a 3-way design whereas the TSi200 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.

EVO4.2 features a 1.18x2.36" AMT (Ribbon) Tweeter, a 2" Midrange and 1 x 6.5" Kevlar Woofer. On the other hand, the TSi200 features a 1" Dome Tweeter and 2 x 5.25" Organic Fiber Woofer with a Crossover frequency at 2500Hz.
Frequency Response
EVO4.2 has a frequency range of 54-22k Hz whereas TSi200 has a frequency range of 50-24k Hz. With a minimum frequency of 50Hz, the TSi200 can go slightly deeper then the EVO4.2's min frequency of 54Hz.
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
EVO4.2 and TSi200 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. EVO4.2 sensitivity is rated at 88 dB and the TSi200's is at 89 dB. This 1 dB difference makes the Polk TSi200 a more sensitive speaker compared to Wharfedale EVO4.2, 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.
TSi200 can handle a max power of 150 watts RMS, whereas EVO4.2 has a max power handling value of 120 watts RMS, 30 watts less than the TSi200.
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
EVO4.2 features Binding post posts which make bi-amping or bi-wiring possible. TSi200 has a Pair of 5-way binding posts - Gold-plated which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
EVO4.2 has a bottom firing port whereas TSi200 has a rear firing ports. Wharfedale EVO4.2's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Polk TSi200 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 EVO4.2's and Polk TSi200's external dimensions. Wharfedale EVO4.2 has external dimensions of 455.0 x 250.0 x 350.0mm (17.9 x 9.8 x 13.7inch) whereas Polk TSi200 has external dimensions of 392.1 x 203.2 x 298.5mm (15.4 x 8.0 x 11.7inch).
Wharfedale EVO4.2 is clearly the larger of the two speakers. Its body is 46.8mm wider, 62.9mm taller and 51.5mm deeper than Polk TSi200.
Below you can see the front view size comparison of Wharfedale EVO4.2 and Polk TSi200 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 EVO4.2 is approximately 875.0cm2 / 135.6inch2 and base area of the Polk TSi200 is approximately 606.6cm2 / 94.0inch2. The EVO4.2 requires 44% more surface area than the TSi200 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 EVO4.2 weighs 13.40kg / 29.5lbs and the Polk TSi200 weighs 7.71kg / 17lbs. This makes the EVO4.2 74% heavier than the TSi200.

These sit in different price classes - Wharfedale EVO4.2 costs roughly 4.3x what Polk TSi200 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 | B | Polk TSi200 digs deeper - 50Hz against 54Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (88dB vs 89dB) - both want much the same power. |
| Headroom | B | Polk TSi200 takes more power (150W vs 120W) - more in hand in a big room. |
| Size | depends | Polk TSi200 is easier to place; Wharfedale EVO4.2 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | A | Wharfedale EVO4.2: bi-amping. |
| Price | B | Polk TSi200 is cheaper - $279 against $1,199, about 77% less; arguably a different class. |
A Wharfedale EVO4.2 B Polk TSi200
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?
Polk TSi200 has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. In a large or open-plan room, Wharfedale EVO4.2 has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Polk TSi200 is the easier speaker to get right. Think about the whole system, not just the speakers: the roughly $920 saved by taking the cheaper pair would buy a subwoofer or a better amplifier, and either usually does more for the sound than the difference between these two.
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.
