In this review, we will be comparing TSi100 and D310, two Passive Bookshelf speakers from Polk Audio and Wharfedale. Let's have a brief look at the main features
of Polk TSi100 and Wharfedale D310 first before getting into our more
detailed comparison.
What size room are the Polk TSi100 and Wharfedale D310 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 Polk TSi100 and Wharfedale D310 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

TSi100 features a 1" Dome Tweeter and 1 x 5.25" Organic Fiber Woofer with a Crossover frequency at 2500Hz. On the other hand, the D310 features a 1" Soft-Dome Tweeter and 1 x 4" Woven Kevlar Woofer .
Frequency Response
TSi100 has a frequency range of 61-24k Hz whereas D310 has a frequency range of 65-20k Hz. With a minimum frequency of 61Hz, the TSi100 can go slightly deeper then the D310's min frequency of 65Hz.
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
TSi100 and D310 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. TSi100 sensitivity is rated at 89 dB and the D310's is at 86 dB. This 3 dB difference makes the Polk TSi100 a more sensitive speaker compared to Wharfedale D310, 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.
TSi100 can handle a max power of 100 watts RMS from the amp the whereas D310 has a max power handling value of 60 watts RMS, 40 watts less than the TSi100.
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
TSi100 features Post type posts and D310 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
TSi100 has a rear firing port whereas D310 has a bottom firing ports. Wharfedale D310'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 Polk TSi100's and Wharfedale D310's external dimensions. Polk TSi100 has external dimensions of 279.4 x 177.8 x 259.0mm ( 11.0 x 7.0 x 10.1inch) whereas Wharfedale D310 has external dimensions of 266.0 x 156.0 x 224.0mm ( 10-7/16 x 6-1/8 x 8-13/16inch) .
Polk TSi100 is clearly the larger of the two speakers. Its body is 21.8mm wider, 13.4mm taller and 35mm deeper than Wharfedale D310.
Below you can see the front view size comparison of Polk TSi100 and Wharfedale D310 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 Polk TSi100 is approximately 460.5cm2 / 71.4inch2 and base area of the Wharfedale D310 is approximately 349.4cm2 / 54.2inch2. The TSi100 requires 32% more surface area than the D310 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 Polk TSi100 weighs 4.53kg / 10lbs and the Wharfedale D310 weighs 4.00kg / 8.8lbs. This makes the TSi100 13% heavier than the D310.
Here is a comparison of how TSi100 and D310's weights compare with the average, max and min weights in Passive Bookshelf class.
