In this review, we will be comparing A120P and Sub 6, two Powered Subwoofer speakers from JBL 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 JBL Stage A120P and Dynaudio Sub 6 first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how the JBL Stage A120P and Dynaudio Sub 6 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 JBL Stage A120Pand Dynaudio Sub 6 have a single woofer setup however the JBL Stage A120P's woofer is 12-inch whereas the Dynaudio Sub 6 features a 9.5-inch woofer.
Frequency Response
A120P has a frequency range of 32-150 Hz whereas Sub 6 has a frequency range of 16-230 Hz. With a minimum frequency of 16Hz, the Sub 6 can go significantly deeper on the low side and provide stronger bass compared to the A120P's min frequency of 32Hz.
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.

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 JBL Stage A120P's and Dynaudio Sub 6's external dimensions. JBL Stage A120P has external dimensions of 415.0 x 393.0 x 475.0mm ( 16-5/16 x 15-7/16 x 18-11/16inch) whereas Dynaudio Sub 6 has external dimensions of 334.0 x 477.0 x 312.0mm ( 13-1/8 x 18-3/4 x 12-1/4inch) .
Dynaudio Sub 6 is 81mm shorter and 163mm less deeper than JBL Stage A120P but it is also 84mm wider.

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 JBL Stage A120P is approximately 1866.8cm2 / 289.4inch2 and base area of the Dynaudio Sub 6 is approximately 1488.2cm2 / 230.7inch2. The A120P requires 25% more surface area than the Sub 6 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 JBL Stage A120P weighs 18.68kg / 41.1lbs and the Dynaudio Sub 6 weighs 20.55kg / 45.2lbs. This makes the Sub 6 10% heavier than the A120P.
Here is a comparison of how A120P and Sub 6's weights compare with the average, max and min weights in Powered Subwoofer class.
