In this review, we will be comparing Bravus II 10D 500W 10" Powered Subwoofer and DB4S, two Powered Subwoofer speakers from Aperion 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 Aperion Bravus II 10D 500W 10" Powered Subwoofer and B&W DB4S first before getting into our more detailed comparison.
The sections below take each area in turn: driver and amplifier, frequency response, physical size and connectivity.
Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Aperion Bravus II 10D 500W 10" Powered Subwooferand B&W DB4S have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
Bravus II 10D 500W 10" Powered Subwoofer has a frequency range of 28-350 Hz whereas DB4S has a frequency range of 10-350 Hz. With a minimum frequency of 10Hz, the DB4S can go significantly deeper on the low side and provide stronger bass compared to the Bravus II 10D 500W 10" Powered Subwoofer's min frequency of 28Hz.
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
Both Aperion Bravus II 10D 500W 10" Powered Subwoofer and B&W DB4S have Acoustic Suspension type cabinets. 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
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Aperion Bravus II 10D 500W 10" Powered Subwoofer's and B&W DB4S's external dimensions. Aperion Bravus II 10D 500W 10" Powered Subwoofer has external dimensions of 381.0 x 342.9 x 342.9mm (15 x 13.5 x 13.5inch) whereas B&W DB4S has external dimensions of 375.0 x 362.0 x 434.0mm (14-3/4 x 14-1/4 x 17-1/16inch).
Aperion Bravus II 10D 500W 10" Powered Subwoofer is 19.1mm narrower and 91.1mm less deeper than B&W DB4S but it is also 6mm taller.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
B&W DB4S needs about 34% more floor or shelf area. B&W DB4S is 91mm deeper, so it stands that much further out from the wall.
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 Aperion Bravus II 10D 500W 10" Powered Subwoofer is approximately 1175.8cm2 / 182.2inch2 and base area of the B&W DB4S is approximately 1571.1cm2 / 243.5inch2. The Bravus II 10D 500W 10" Powered Subwoofer requires 25% less surface area than the DB4S 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 Aperion Bravus II 10D 500W 10" Powered Subwoofer weighs 17.24kg / 37.9lbs and the B&W DB4S weighs 26.05kg / 57.3lbs. This makes the DB4S 51% heavier than the Bravus II 10D 500W 10" Powered Subwoofer.
Here is a comparison of how Bravus II 10D 500W 10" Powered Subwoofer and DB4S's weights compare with the average, max and min weights in Powered Subwoofer class.

Different price classes - B&W DB4S costs roughly 2.4x what Aperion Bravus II 10D 500W 10" Powered Subwoofer does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | B | B&W DB4S goes deeper - 10Hz against 28Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | B&W DB4S has the bigger amplifier - 1000W against 500W RMS, about 3dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | evenly matched | Near-identical radiating area (10" against 10"). |
| Enclosure | evenly matched | Both are sealed designs, so they roll off in much the same way. |
| Cabinet size | depends | Aperion Bravus II 10D 500W 10" Powered Subwoofer is about 24% smaller by volume. In a subwoofer that is a real trade rather than a preference: box volume is how you get output low down without a bigger amplifier. |
| Price | A | Aperion Bravus II 10D 500W 10" Powered Subwoofer costs less - $899 against $2,199, about 59% less. |
A Aperion Bravus II 10D 500W 10" Powered Subwoofer B B&W DB4S
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both subwoofers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: B&W DB4S measures better, Aperion Bravus II 10D 500W 10" Powered Subwoofer costs about 59% less. In a normal room, placement will make a bigger difference than the gap between these two. Two small subwoofers beat one big one in most rooms - a pair evens out the room modes in a way no single box can, whatever its specs. At $899 each, two Aperion Bravus II 10D 500W 10" Powered Subwoofer cost about $1,798 against $2,199 for one of the other, which is worth a thought.
One thing outweighs everything above: where the subwoofer stands. Room modes can add or remove 10dB or more at a given seat, which is far larger than any difference on this page. Before spending more, try the sub in two or three positions - the crawl test, where you put it in the listening seat and crawl the room to find where the bass sounds best, costs nothing and usually beats an upgrade.
