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 Ultra Bookshelf have the same Impedance of 8 ohms and their sensitivity is also same at 87 dB.
Sensitivity

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 150 watts RMS from the amp the whereas D320 has a max power handling value of 100 watts RMS , 50 watts less than the Ultra Bookshelf.
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
Ultra Bookshelf features 5-way post posts which make bi-amping or bi-wiring possible. D320 has a Post which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
D320 has a bottom firing port whereas Ultra Bookshelf has a rear firing ports. Wharfedale D320's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to SVS Ultra Bookshelf 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 D320's and SVS Ultra Bookshelf'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 SVS Ultra Bookshelf has external dimensions of 380.0 x 218.0 x 281.0mm ( 14-15/16 x 8-9/16 x 11-1/16inch) .
SVS Ultra Bookshelf is clearly the larger of the two speakers. Its body is 37mm wider, 59mm taller and 4mm deeper than Wharfedale D320.
Below you can see the front view size comparison of Wharfedale D320 and SVS Ultra Bookshelf 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 Wharfedale D320 is approximately 501.4cm2 / 77.7inch2 and base area of the SVS Ultra Bookshelf is approximately 612.6cm2 / 95.0inch2. The D320 requires 18% less surface area than the Ultra Bookshelf which gives it a small advantage 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 Wharfedale D320 weighs 6.02kg / 13.2lbs and the SVS Ultra Bookshelf weighs 8.64kg / 19lbs. This makes the Ultra Bookshelf 44% heavier than the D320.
Here is a comparison of how D320 and Ultra Bookshelf's weights compare with the average, max and min weights in Passive Bookshelf class.
