In this review, we will be comparing ProSub 1000 and ASW610, two Powered Subwoofer speakers from Definitive Technology and Bowers Wilkins. 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 Definitive ProSub 1000 and B&W ASW610 first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how the Definitive ProSub 1000 and B&W ASW610 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.Definitive ProSub 1000and B&W ASW610 have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
ProSub 1000 has a frequency range of 18-150 Hz whereas ASW610 has a frequency range of 27-140 Hz. With a minimum frequency of 18Hz, the ProSub 1000 can go significantly deeper on the low side and provide stronger bass compared to the ASW610'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 Definitive ProSub 1000 has a Passive Radiator type cabinet. Passive Radiator type subwoofers sports a non-powered cone that moves in response to the main woofer to move air out in order to generate stronger bass in a smaller body compared to ported or sealed designs. On the other hand the B&W ASW610 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 Definitive ProSub 1000's and B&W ASW610's external dimensions. Definitive ProSub 1000 has external dimensions of 366.0 x 307.0 x 486.0mm ( 14-3/8 x 12-1/16 x 19-1/8inch) whereas B&W ASW610 has external dimensions of 321.0 x 312.0 x 394.0mm ( 12-5/8 x 12-1/4 x 15-1/2inch) .
B&W ASW610 is 45mm shorter and 92mm less deeper than Definitive ProSub 1000 but it is also 5mm 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 Definitive ProSub 1000 is approximately 1492.0cm2 / 231.3inch2 and base area of the B&W ASW610 is approximately 1229.3cm2 / 190.5inch2. The ProSub 1000 requires 21% more surface area than the ASW610 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 Definitive ProSub 1000 weighs 14.09kg / 31lbs and the B&W ASW610 weighs 12.55kg / 27.6lbs. This makes the ProSub 1000 12% heavier than the ASW610.
Here is a comparison of how ProSub 1000 and ASW610's weights compare with the average, max and min weights in Powered Subwoofer class.
