In this review, we will be comparing RP-1200SW and MilleniaSub, two Powered Subwoofer speakers from Klipsch and Paradigm. Being Powered subwoofers, they both have built-in amplifiers so you don't need an external power amp or an integrated amp to power them. Let's have a brief look at the main features of Klipsch RP-1200SW 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.Both Klipsch RP-1200SWand Paradigm MilleniaSub have a single woofer setup however the Klipsch RP-1200SW's woofer is 12-inch whereas the Paradigm MilleniaSub features a -inch woofer.
Frequency Response
RP-1200SW has a frequency range of 16.5-138 Hz whereas MilleniaSub has a frequency range of 24-150 Hz. With a minimum frequency of 17Hz, the RP-1200SW can go significantly deeper on the low side and provide stronger bass compared to the MilleniaSub's min frequency of 24Hz.
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 Subwoofer class in our database.

Cabinet Type
The Klipsch RP-1200SW 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 Paradigm MilleniaSub 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
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 Klipsch RP-1200SW's and Paradigm MilleniaSub's external dimensions. Klipsch RP-1200SW has external dimensions of 482.0 x 432.0 x 659.0mm (18-15/16inch x 17inch x 25-15/16inch) 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).
Klipsch RP-1200SW is clearly the larger of the two speakers. Its body is 252mm wider, 96mm taller and 192mm deeper than Paradigm MilleniaSub.
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 Klipsch RP-1200SW is approximately 2846.9cm2 / 441.3inch2 and base area of the Paradigm MilleniaSub is approximately 840.6cm2 / 130.3inch2. The RP-1200SW requires 239% more surface area than the MilleniaSub 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 Klipsch RP-1200SW weighs 31.18kg / 68.6lbs and the Paradigm MilleniaSub weighs 10.91kg / 24lbs. This makes the RP-1200SW 186% heavier than the MilleniaSub.
Here is a comparison of how RP-1200SW and MilleniaSub's weights compare with the average, max and min weights in Powered Subwoofer class.
