Frequency Response
Defiance X12 has a frequency range of 20-230 Hz whereas Dynamo 1100X has a frequency range of 22-200 Hz. With a minimum frequency of 20Hz, the Defiance X12 can go slightly deeper then the Dynamo 1100X's min frequency of 22Hz.

Cabinet Type
The Paradigm Defiance X12 has a Bass Reflex type cabinet. Bass Reflex type subwoofers (aka Ported, Vented or Reflex Port) have enclosures that uses a port, hole or vent cut into the cabinet. Ported designs are generally more efficient than the Sealed designs. On the other hand the MartinLogan 1100X have Acoustic Suspension type enclosure. 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
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 Paradigm Defiance X12's and MartinLogan 1100X's external dimensions. Paradigm Defiance X12 has external dimensions of 494.0 x 459.0 x 529.0mm ( 19-7/16inch x 18-1/16inch x 20-13/16inch ) whereas MartinLogan 1100X has external dimensions of 435.0 x 381.0 x 410.0mm ( 17-1/8 x 15 x 16-1/8inch) .
Paradigm Defiance X12 is clearly the larger of the two speakers. Its body is 78mm wider, 59mm taller and 119mm deeper than MartinLogan 1100X.

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 Paradigm Defiance X12 is approximately 2428.1cm2 / 376.4inch2 and base area of the MartinLogan 1100X is approximately 1562.1cm2 / 242.1inch2. The Defiance X12 requires 55% more surface area than the Dynamo 1100X 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 Paradigm Defiance X12 weighs 28.18kg / 62lbs and the MartinLogan 1100X weighs 20.91kg / 46lbs. This makes the Defiance X12 35% heavier than the Dynamo 1100X.
