Perlisten D15s is clearly the larger of the two speakers. Its body is 92.1mm wider, 110.1mm taller and 15.1mm deeper than Polk Monitor XT12.
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 Perlisten D15s is approximately 2501.0cm2 / 387.7inch2 and base area of the Polk Monitor XT12 is approximately 1978.8cm2 / 306.7inch2. The D15s requires 26% more surface area than the Monitor XT12 which gives it a small disadvantage 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 Perlisten D15s weighs 46.00kg / 101.2lbs and the Polk Monitor XT12 weighs 17.73kg / 39lbs. This makes the D15s 159% heavier than the Monitor XT12.
