D300C features a 1" Soft-Dome Tweeter and 2 x 5" Black woven Kevlar Cone Woofer . On the other hand, the Monitor XT30 features a 1" Terylene High-res dome Tweeter and 2 x 5.25" bi-laminate paper cone Woofer .
Frequency Response
D300C has a frequency range of 65-20k Hz whereas Monitor XT30 has a frequency range of 55-40k Hz. With a minimum frequency of 55Hz, the Monitor XT30 can go significantly deeper on the low side and provide stronger bass compared to the D300C's min frequency of 65Hz.
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 Center Channel 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
D300C and Monitor XT30 have the same Impedance of 8 ohms and their sensitivity is also same at 89 dB.

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.
D300C can handle a max power of 200 watts RMS from the amp the whereas D300C has a max power handling value of 120 watts RMS , 80 watts less than the Monitor XT30.
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
D300C features Post posts which make bi-amping or bi-wiring possible. Monitor XT30 has a 5-Way post which doesn't feature bi-amping/bi-wiring.
Wharfedale D300C's Post terminals allows Bi-amping or bi-wiring
Polk XT30's 5-Way post terminals
Cabinet Type and Port Position
D300C has a bottom firing port whereas Monitor XT30 has a rear firing ports. Wharfedale D300C's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Polk XT30 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 D300C's and Polk XT30's external dimensions. Wharfedale D300C has external dimensions of 190 x 510 x 232mm ( 7.8) whereas Polk XT30 has external dimensions of 166.0 x 485.0 x 208.0mm ( 6-1/2 x 19-1/16 x 8-3/16inch) .
Wharfedale D300C is clearly the larger of the two speakers. Its body is 25mm wider, 24mm taller and 24mm deeper than Polk XT30.
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 D300C is approximately 1183.0cm2 / 183.4inch2 and base area of the Polk XT30 is approximately 1008.8cm2 / 156.4inch2. The D300C requires 17% more surface area than the Monitor XT30 which gives it a small disadvantage on placement in tight spaces.
