In this review, we will be comparing Sub 600P and A120P, two Powered Subwoofer speakers from Focal and JBL. 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 Focal Sub 600P and JBL Stage A120P first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how the Focal Sub 600P and JBL Stage A120P 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.Focal Sub 600Pand JBL Stage A120P have the same driver set up: Both subwoofers have 1 x 12" drivers.
Frequency Response
Sub 600P has a frequency range of 28-270 Hz whereas A120P has a frequency range of 32-150 Hz. With a minimum frequency of 28Hz, the Sub 600P can go slightly deeper then 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.

Cabinet Type
The Focal Sub 600P has a Acoustic Suspension type cabinet. 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. On the other hand the JBL Stage A120P have Bass reflex type enclosure.
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 Focal Sub 600P's and JBL Stage A120P's external dimensions. Focal Sub 600P has external dimensions of 400.0 x 400.0 x 425.0mm ( 15-3/4 x 15-3/4 x 16-3/4inch) whereas 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) .
Focal Sub 600P is 15mm shorter and 50mm less deeper than JBL Stage A120P but it is also 7mm 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 Focal Sub 600P is approximately 1700.0cm2 / 263.5inch2 and base area of the JBL Stage A120P is approximately 1866.8cm2 / 289.4inch2. The Sub 600P requires 9% less surface area than the A120P which gives it a small advantage 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 Focal Sub 600P weighs 21.00kg / 46.2lbs and the JBL Stage A120P weighs 18.68kg / 41.1lbs. This makes the Sub 600P 12% heavier than the A120P.
Here is a comparison of how Sub 600P and A120P's weights compare with the average, max and min weights in Powered Subwoofer class.
