Drivers

One of the fundamental differences between these two speakers is that EVO4.2 is a 3-way design whereas the TSi100 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.

Driver Wharfedale EVO4.2 Polk TSi100
Driver Setup 3-way 2-way
Tweeter 1.18x2.36-inch 1-inch
Midrange 1 x 2-inch -
Woofer 1 x 6.5-inch 1 x 5.25-inch

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 TSi100 features a 1" Dome Tweeter and 1 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 TSi100 has a frequency range of 61-24k Hz. With a minimum frequency of 54Hz, the EVO4.2 can go significantly deeper on the low side and provide stronger bass compared to the TSi100's min frequency of 61Hz.

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

EVO4.2 and TSi100 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 TSi100's is at 89 dB. This 1 dB difference makes the Polk TSi100 a more sensitive speaker compared to Wharfedale EVO4.2, 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.

EVO4.2 can handle a max power of 120 watts RMS from the amp the whereas TSi100 has a max power handling value of 100 watts RMS, 20 watts less than the EVO4.2.

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

EVO4.2 features Post posts which make bi-amping or bi-wiring possible. TSi100 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 TSi100 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 TSi100 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 Wharfedale EVO4.2's and Polk TSi100'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 TSi100 has external dimensions of 279.4 x 177.8 x 259.0mm ( 11.0 x 7.0 x 10.1inch) .

Wharfedale EVO4.2 is clearly the larger of the two speakers. Its body is 72.2mm wider, 175.6mm taller and 91mm deeper than Polk TSi100.

Below you can see the front view size comparison of Wharfedale EVO4.2 and Polk TSi100 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 TSi100 is approximately 460.5cm2 / 71.4inch2. The EVO4.2 requires 90% more surface area than the TSi100 which gives it a small disadvantage on placement in tight spaces.

Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

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 TSi100 weighs 4.53kg / 10lbs. This makes the EVO4.2 196% heavier than the TSi100.
