In this review, we will be comparing RP-1200SW and Sub 3, two Powered Subwoofer speakers from Klipsch and Dynaudio. 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 Dynaudio Sub 3 first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how the Klipsch RP-1200SW and Dynaudio Sub 3 compare and hopefully end up with enough arguments to decide which one of these subwoofers is the better choice for you.

The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Both Klipsch RP-1200SWand Dynaudio Sub 3 have a single woofer setup however the Klipsch RP-1200SW's woofer is 12-inch whereas the Dynaudio Sub 3 features a 9.5-inch woofer.
Frequency Response
RP-1200SW has a frequency range of 16.5-138 Hz whereas Sub 3 has a frequency range of 22-175 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 Sub 3's min frequency of 22Hz.
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 Dynaudio Sub 3 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 Klipsch RP-1200SW's and Dynaudio Sub 3'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 Dynaudio Sub 3 has external dimensions of 277.0 x 269.0 x 366.0mm ( 10-7/8 x 10-9/16 x 14-3/8inch) .
Klipsch RP-1200SW is clearly the larger of the two speakers. Its body is 163mm wider, 205mm taller and 293mm deeper than Dynaudio Sub 3.

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 Dynaudio Sub 3 is approximately 984.5cm2 / 152.6inch2. The RP-1200SW requires 189% more surface area than the Sub 3 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 Dynaudio Sub 3 weighs 10.50kg / 23.1lbs. This makes the RP-1200SW 197% heavier than the Sub 3.
