In this review, we will be comparing D330 and Airmotiv T-Zero+, two Passive Floor-standing speakers from Wharfedale and Emotiva. Let's have a brief look at the main features
of Wharfedale D330 and Emotiva Airmotiv T-Zero+ first before getting into our more
detailed comparison.
What size room are the Wharfedale D330 and Emotiva Airmotiv T-Zero+ 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 Wharfedale D330 and Emotiva Airmotiv T-Zero+ 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 Airmotiv T-Zero+ 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 Airmotiv T-Zero+ features a 25×32 mm" folded ribbon Tweeter and 2 x 5.25" woven fiber cone Woofer with a Crossover frequency at 2500Hz.
Frequency Response
D330 has a frequency range of 56-20k Hz whereas Airmotiv T-Zero+ has a frequency range of 48-28 kHz. With a minimum frequency of 40Hz, the D330 can go significantly deeper on the low side and provide stronger bass compared to the Airmotiv T-Zero+'s min frequency of 48Hz.
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.

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 is a 8 ohms speaker compared to the Airmotiv T-Zero+ which has a nominal impedance of 4 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Airmotiv T-Zero+ can provide this impedance level.
These two speakers also have different sensitivity levels. D330 sensitivity is rated at 88 dB and the Airmotiv T-Zero+'s is rated at 87 dB. This 1 dB difference makes the Wharfedale D330 a more sensitive speaker compared to Emotiva Airmotiv T-Zero+, 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 120 watts RMS from the amp the whereas Airmotiv T-Zero+ 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.
Cabinet Type and Port Position
D330 has a bottom firing port whereas Airmotiv T-Zero+ has a rear firing ports. Wharfedale D330's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Emotiva Airmotiv T-Zero+ 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 D330's and Emotiva Airmotiv T-Zero+'s external dimensions. Wharfedale D330 has external dimensions of 965 x 200 x 338mm ( 38.0" x 7.9" x 13.3") whereas Emotiva Airmotiv T-Zero+ has external dimensions of 969.0 x 969.0 x 267.0mm ( 38-1/8 x 38-1/8 x 10-1/2inch) .
Wharfedale D330 is 769mm narrower and 4mm shorter than Emotiva Airmotiv T-Zero+ but it is also 71mm deeper.
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 Emotiva Airmotiv T-Zero+ is approximately 2587.2cm2 / 401.0inch2. The D330 requires 74% less surface area than the Airmotiv T-Zero+ which gives it a small advantage on placement in tight spaces.
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 D330 weighs 18.20kg / 40lbs and the Emotiva Airmotiv T-Zero+ weighs 13.20kg / 29lbs. This makes the D330 38% heavier than the Airmotiv T-Zero+.
Here is a comparison of how D330 and Airmotiv T-Zero+'s weights compare with the average, max and min weights in Passive Floor-standing class.
