What size room are the Wharfedale D330 and Polk TSi300 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.)
In the following sections, we will get into more detail in order to better understand how the Wharfedale D330 and Polk TSi300 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that D330 is a 3-way design whereas the TSi300 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.

D330 features a 1" Soft-Dome Tweeter , a 5" Midrange and 1 x 5" Black woven Kevlar Cone Woofer . On the other hand, the TSi300 features a 1" Tweeter and 2 x 5.25" Organic Fiber Woofer .
Frequency Response
D330 has a frequency range of 56-20k Hz whereas TSi300 has a frequency range of 47-24k Hz. With a minimum frequency of 40Hz, the D330 can go significantly deeper on the low side and provide stronger bass compared to the TSi300's min frequency of 47Hz.
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 Floor-standing class in our database.

High Frequency
Floor-standing Speakers
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
D330 and TSi300 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. D330 sensitivity is rated at 88 dB and the TSi300's is at 90 dB. This 2 dB difference makes the Polk TSi300 a more sensitive speaker compared to Wharfedale D330, 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.
D330 can handle a max power of 150 watts RMS from the amp the whereas D330 has a max power handling value of 120 watts RMS , 30 watts less than the TSi300.
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
TSi300 features 5-way post posts which make bi-amping or bi-wiring possible. D330 has a Post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both D330 and TSi300 have bottom firing ports.
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 D330's and Polk TSi300's external dimensions. Wharfedale D330 has external dimensions of 965 x 200 x 338mm ( 38.0" x 7.9" x 13.3") whereas Polk TSi300 has external dimensions of 921.0 x 208.0 x 299.0mm ( 36-1/4 x 8-3/16 x 11-3/4inch) .
Polk TSi300 is 44mm shorter and 39mm less deeper than Wharfedale D330 but it is also 8mm wider.
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 D330 is approximately 676.0cm2 / 104.8inch2 and base area of the Polk TSi300 is approximately 621.9cm2 / 96.4inch2. The D330 requires 9% more surface area than the TSi300 which gives it a small disadvantage on placement in tight spaces.
