In this review, we will be comparing SuperSub X and SubSeries 450, two Powered Subwoofer speakers from GoldenEar and PSB. 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 GoldenEar SuperSub X and PSB SubSeries 450 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.GoldenEar SuperSub X and PSB SubSeries 450 have a totally different setup: the GoldenEar SuperSub X features 2 x 8-inch drivers whereas the SubSeries 450 features 1 x 12-inch drivers.
Frequency Response
SuperSub X has a frequency range of 12-250 Hz whereas SubSeries 450 has a frequency range of 20-150 Hz. With a minimum frequency of 12Hz, the SuperSub X can go significantly deeper on the low side and provide stronger bass compared to the SubSeries 450's min frequency of 20Hz.
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 GoldenEar SuperSub X and PSB SubSeries 450 have Passive Radiator type cabinets. 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.
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 GoldenEar SuperSub X's and PSB SubSeries 450's external dimensions. GoldenEar SuperSub X has external dimensions of 324.0 x 356.0 x 388.0mm (12-3/4inch x 14inch x 15-1/4inch) whereas PSB SubSeries 450 has external dimensions of 401.0 x 413.0 x 453.0mm (15-3/4 x 16-1/4 x 17-13/16inch).
PSB SubSeries 450 is clearly the larger of the two speakers. Its body is 57mm wider, 77mm taller and 65mm deeper than GoldenEar SuperSub X.
Below you can see the front view size comparison of GoldenEar SuperSub X and PSB SubSeries 450 in scale.

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 GoldenEar SuperSub X is approximately 1381.3cm2 / 214.1inch2 and base area of the PSB SubSeries 450 is approximately 1870.9cm2 / 290.0inch2. The SuperSub X requires 26% less surface area than the SubSeries 450 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 GoldenEar SuperSub X weighs 18.18kg / 40lbs and the PSB SubSeries 450 weighs 20.45kg / 45lbs. This makes the SubSeries 450 12% heavier than the SuperSub X.
Here is a comparison of how SuperSub X and SubSeries 450's weights compare with the average, max and min weights in Powered Subwoofer class.

Size, drawn to scale
Both subwoofers 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 floor and pushed back to the same wall, so the bigger one visibly takes more of the room.
PSB SubSeries 450 needs about 35% more floor area. PSB SubSeries 450 stands 65mm further into the room. PSB SubSeries 450 is 77mm taller.

No single best subwoofer here. Your room, where the box can physically go, and whether this is mainly for films or mainly for music will settle it long before the specs do.
| Area | Better | Why |
|---|
| Bass depth | A | GoldenEar SuperSub X goes deeper - 12Hz against 20Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | A | GoldenEar SuperSub X has the bigger amplifier - 1400W against 400W RMS, about 5.4dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | evenly matched | Near-identical radiating area (2 x 8" against 12"). |
| Enclosure | evenly matched | Both are passive radiator designs, so they roll off in much the same way. |
| Speaker-level inputs | B | PSB SubSeries 450 takes a speaker-level connection as well as line level. That is what lets it work with an integrated amplifier or a vintage receiver that has no subwoofer output at all. |
| Phase control | B | PSB SubSeries 450 has a phase control. Without one, the only way to fix a cancellation at the crossover is to move the box. |
| Driver placement | depends | GoldenEar SuperSub X fires side and PSB SubSeries 450 fires front. 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 X is about 40% 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. |
| Warranty | A | GoldenEar SuperSub X carries 3 years on parts against 1 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | A | GoldenEar SuperSub X costs less - $1,499 against $1,999, about 25% less. |
A GoldenEar SuperSub X B PSB SubSeries 450
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?
GoldenEar SuperSub X has the edge on paper, though not by much. The "depends" rows are more likely to decide this than the score is. Check your amplifier first: if it has no subwoofer or preamp output, PSB SubSeries 450 is the only one of these two you can connect at all. If placement is the constraint - a corner, behind a sofa, under a desk - GoldenEar SuperSub X 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.
