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.

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.

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 D300C weighs 8.00kg / 17.6lbs and the Polk XT30 weighs 5.91kg / 13lbs. This makes the D300C 35% heavier than the Monitor XT30.
