Let's have a brief look at the main features of KEF KC62 and Paradigm MilleniaSub first before getting into our more detailed comparison.
The sections below take each area in turn: driver and amplifier, frequency response, physical size and connectivity.

Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.KEF KC62 and Paradigm MilleniaSub have a totally different setup: the KEF KC62 features 2 x 6.5-inch drivers whereas the MilleniaSub features 1 x -inch drivers.
Frequency Response
KC62 has a frequency range of 11-200 Hz whereas MilleniaSub has a frequency range of 24-150 Hz. With a minimum frequency of 11Hz, the KC62 can go significantly deeper on the low side and provide stronger bass compared to the MilleniaSub's min frequency of 24Hz.

Cabinet Type
Both KEF KC62 and Paradigm MilleniaSub have Acoustic Suspension type cabinets. Acoustic Suspension aka Sealed type subwoofers have enclosures that are sealed hence no ports or holes exists on the cabinet. Sealed designs helps to provide more accurate and tight bass responses compared to ported designs.
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 KEF KC62's and Paradigm MilleniaSub's external dimensions. KEF KC62 has external dimensions of 245.0 x 258.0 x 281.0mm (9-5/8inch x 10-1/8inch x 11-1/16inch) whereas Paradigm MilleniaSub has external dimensions of 386.0 x 180.0 x 467.0mm (15-3/16inch x 7-1/16inch x 18-3/8inch).
KEF KC62 is 141mm shorter and 186mm less deeper than Paradigm MilleniaSub but it is also 78mm wider.
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 KEF KC62 is approximately 725.0cm2 / 112.4inch2 and base area of the Paradigm MilleniaSub is approximately 840.6cm2 / 130.3inch2. The KC62 requires 14% less surface area than the MilleniaSub which gives it a small advantage on placement in tight spaces.
Weight Comparison The weight of a subwoofer may become an important factor if you need to move and reposition the unit often to find the optimal positioning, also known as 'Subwoofer Crawling'. The KEF KC62 weighs 14.05kg / 30.9lbs and the Paradigm MilleniaSub weighs 10.91kg / 24lbs. This makes the KC62 29% heavier than the MilleniaSub.
Here is a comparison of how KC62 and MilleniaSub's weights compare with the average, max and min weights in Powered Subwoofer class.
