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 D320 and Wharfedale D330 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 D320 is a 2-way design whereas the D330 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.

D320 features a 1" Soft-Dome Tweeter and 1 x 5" Woven Kevlar Woofer . On the other hand, the D330 features a 1" Soft-Dome Tweeter , a 5" Midrange and 1 x 5" Black woven Kevlar Cone Woofer .
Frequency Response
D320 and D330 has exactly the same frequency range of 56-20k Hz. With a minimum frequency of 40Hz, the D330 can go significantly deeper on the low side and provide stronger bass compared to the D320's min frequency of 56Hz.
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
D320 and D330 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. D320 sensitivity is rated at 87 dB and the D330's is at 88 dB. This 1 dB difference makes the Wharfedale D330 a more sensitive speaker compared to Wharfedale D320, 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.
D320 can handle a max power of 120 watts RMS from the amp the whereas D320 has a max power handling value of 100 watts RMS , 20 watts less than the D330.
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
D320 features Post type posts and D330 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

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 D320's and Wharfedale D330's external dimensions. Wharfedale D320 has external dimensions of 321.0 x 181.0 x 277.0mm ( 12-5/8 x 7-1/8 x 10-7/8inch) whereas Wharfedale D330 has external dimensions of 965 x 200 x 338mm ( 38.0" x 7.9" x 13.3") .
Wharfedale D330 is clearly the larger of the two speakers. Its body is 19mm wider, 644mm taller and 61mm deeper than Wharfedale D320.
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 D320 is approximately 501.4cm2 / 77.7inch2 and base area of the Wharfedale D330 is approximately 676.0cm2 / 104.8inch2. The D320 requires 26% less surface area than the D330 which gives it a small advantage on placement in tight spaces.
