In this review, we will be comparing SPL-100 and Sub 3, two Powered Subwoofer speakers from Klipsch and Dynaudio.

Let's have a brief look at the main features of Klipsch SPL-100 and Dynaudio Sub 3 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 SPL-100and Dynaudio Sub 3 have a single woofer setup however the Klipsch SPL-100's woofer is 10-inch whereas the Dynaudio Sub 3 features a 9.5-inch woofer.
Frequency Response
SPL-100 has a frequency range of 27-125 Hz whereas Sub 3 has a frequency range of 22-175 Hz. With a minimum frequency of 22Hz, the Sub 3 can go significantly deeper on the low side and provide stronger bass compared to the SPL-100's min frequency of 27Hz.
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 SPL-100 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
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 SPL-100's and Dynaudio Sub 3's external dimensions. Klipsch SPL-100 has external dimensions of 418.0 x 358.0 x 478.0mm (16-7/16 x 14-1/16 x 18-13/16inch) 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 SPL-100 is clearly the larger of the two speakers. Its body is 89mm wider, 141mm taller and 112mm 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 SPL-100 is approximately 1711.2cm2 / 265.2inch2 and base area of the Dynaudio Sub 3 is approximately 984.5cm2 / 152.6inch2. The SPL-100 requires 74% 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 SPL-100 weighs 16.82kg / 37lbs and the Dynaudio Sub 3 weighs 10.50kg / 23.1lbs. This makes the SPL-100 60% heavier than the Sub 3.
Here is a comparison of how SPL-100 and Sub 3's weights compare with the average, max and min weights in Powered Subwoofer class.
