History
What size room are the Wharfedale D320 and Wharfedale D330 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.)

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.
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
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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
D330 can handle a max power of 120 watts RMS, whereas D320 has a max power handling value of 100 watts RMS, 20 watts less than the D330.
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.

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
D320 features Post type posts and D330 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

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 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.
