Let's have a brief look at the main features of Aperion Bravus III B215S Dual 15" Slim Cinema Powered Subwoofer and GoldenEar SuperSub XXL 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.Both Aperion Bravus III B215S Dual 15" Slim Cinema Powered Subwooferand GoldenEar SuperSub XXL have a double woofer setup however the Aperion Bravus III B215S Dual 15" Slim Cinema Powered Subwoofer's woofer is 15-inch whereas the GoldenEar SuperSub XXL features a 12-inch woofer.

Ported designs are generally more efficient than the Sealed designs. On the other hand the GoldenEar SuperSub XXL have Passive Radiator type enclosure. 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.

A ported subwoofer against a passive radiator one. That is the most consequential line on this page: it decides how the bass rolls off, how it behaves in a small room, and how much output you get for the size of the box.
| Area | Better | Why |
|---|
| Bass depth | B | GoldenEar SuperSub XXL goes deeper - 10Hz against 17Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | evenly matched | Much the same amplifier (1300W vs 1600W RMS) - under 1dB apart. |
| Driver area | A | Aperion Bravus III B215S Dual 15" Slim Cinema Powered Subwoofer moves more air: 2 x 15" against 2 x 12" is 1.56x the cone area, not the 1.25x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | Aperion Bravus III B215S Dual 15" Slim Cinema Powered Subwoofer is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning; GoldenEar SuperSub XXL is passive radiator - a passive radiator behaves like a port without the pipe noise, and suits a slim cabinet. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Driver placement | depends | Aperion Bravus III B215S Dual 15" Slim Cinema Powered Subwoofer fires front and GoldenEar SuperSub XXL fires side. A down-firing driver is more forgiving of a grille-less look and of a hard floor; a front-firing one is the safer choice on a thick carpet or a suspended timber floor. |
| Cabinet size | depends | GoldenEar SuperSub XXL is about 48% 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 | B | GoldenEar SuperSub XXL costs less - $2,499 against $4,499, about 44% less. |
A Aperion Bravus III B215S Dual 15" Slim Cinema Powered Subwoofer B GoldenEar SuperSub XXL
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?
Neither runs away with it - they trade advantages. Let your room size and where the box can actually stand settle it. 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 $2,499 each, two GoldenEar SuperSub XXL cost about $4,998 against $4,499 for one of the other, which is worth a thought. If placement is the constraint - a corner, behind a sofa, under a desk - GoldenEar SuperSub XXL is the one that will actually go there, and a well-placed small subwoofer beats a badly-placed big one every time.
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.
