In this review, we will be comparing L10cs and PB-1000, two Powered Subwoofer speakers from JBL and SVS. 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 L10cs and SVS PB-1000 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 L10cs and SVS PB-1000 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.JBL L10csand SVS PB-1000 have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
L10cs has a frequency range of 32-150 Hz whereas PB-1000 has a frequency range of 19-270 Hz. With a minimum frequency of 19Hz, the PB-1000 can go significantly deeper on the low side and provide stronger bass compared to the L10cs'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.

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 L10cs's and SVS PB-1000's external dimensions. JBL L10cs has external dimensions of 391.0 x 337.0 x 413.0mm ( 15-3/8inch x 13-1/4inch x 16-1/4inch ) whereas SVS PB-1000 has external dimensions of 480.0 x 381.0 x 532.0mm ( 18-7/8 x 15 x 20-15/16inch) .
SVS PB-1000 is clearly the larger of the two speakers. Its body is 44mm wider, 89mm taller and 119mm deeper than JBL L10cs.
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 L10cs is approximately 1391.8cm2 / 215.7inch2 and base area of the SVS PB-1000 is approximately 2026.9cm2 / 314.2inch2. The L10cs requires 31% less surface area than the PB-1000 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 JBL L10cs weighs 14.09kg / 31lbs and the SVS PB-1000 weighs 20.91kg / 46lbs. This makes the PB-1000 48% heavier than the L10cs.
Here is a comparison of how L10cs and PB-1000's weights compare with the average, max and min weights in Powered Subwoofer class.
