In this review, we will be comparing PB-1000 and Sub 3, two Powered Subwoofer speakers from SVS 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 SVS PB-1000 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 SVS PB-1000 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.

Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Both SVS PB-1000and Dynaudio Sub 3 have a single woofer setup however the SVS PB-1000's woofer is 10-inch whereas the Dynaudio Sub 3 features a 9.5-inch woofer.
Frequency Response
PB-1000 has a frequency range of 19-270 Hz whereas Sub 3 has a frequency range of 22-175 Hz. With a minimum frequency of 19Hz, the PB-1000 can go slightly deeper then 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 SVS PB-1000 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 SVS PB-1000's and Dynaudio Sub 3's external dimensions. SVS PB-1000 has external dimensions of 480.0 x 381.0 x 532.0mm ( 18-7/8 x 15 x 20-15/16inch) 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) .
SVS PB-1000 is clearly the larger of the two speakers. Its body is 112mm wider, 203mm taller and 166mm deeper than Dynaudio Sub 3.
Below you can see the front view size comparison of SVS PB-1000 and Dynaudio Sub 3 in scale.

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 SVS PB-1000 is approximately 2026.9cm2 / 314.2inch2 and base area of the Dynaudio Sub 3 is approximately 984.5cm2 / 152.6inch2. The PB-1000 requires 106% 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 SVS PB-1000 weighs 20.91kg / 46lbs and the Dynaudio Sub 3 weighs 10.50kg / 23.1lbs. This makes the PB-1000 99% heavier than the Sub 3.
Here is a comparison of how PB-1000 and Sub 3's weights compare with the average, max and min weights in Powered Subwoofer class.
