In this review, we will be comparing RP-1400CSW and SuperSub X, two Powered Subwoofer speakers from Klipsch and GoldenEar. 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 Klipsch RP-1400CSW and GoldenEar SuperSub X 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.Klipsch RP-1400CSW and GoldenEar SuperSub X have a totally different setup: the Klipsch RP-1400CSW features 1 x 14-inch drivers whereas the SuperSub X features 2 x 8-inch drivers.
Frequency Response
RP-1400CSW has a frequency range of 15-180 Hz whereas SuperSub X has a frequency range of 12-250 Hz. With a minimum frequency of 12Hz, the SuperSub X can go slightly deeper then the RP-1400CSW's min frequency of 15Hz.
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 Klipsch RP-1400CSW has a Acoustic Suspension type cabinet. 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. On the other hand the GoldenEar SuperSub X 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.
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 Klipsch RP-1400CSW's and GoldenEar SuperSub X's external dimensions. Klipsch RP-1400CSW has external dimensions of 444.0 x 421.6 x 421.6mm (17.48inch x 16.6inch x 16.6inch) whereas GoldenEar SuperSub X has external dimensions of 324.0 x 356.0 x 388.0mm (12-3/4inch x 14inch x 15-1/4inch).
Klipsch RP-1400CSW is clearly the larger of the two speakers. Its body is 65.6mm wider, 120mm taller and 33.6mm deeper than GoldenEar SuperSub X.
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 Klipsch RP-1400CSW is approximately 1777.5cm2 / 275.5inch2 and base area of the GoldenEar SuperSub X is approximately 1381.3cm2 / 214.1inch2. The RP-1400CSW requires 29% more surface area than the SuperSub X 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 Klipsch RP-1400CSW weighs 27.08kg / 59.6lbs and the GoldenEar SuperSub X weighs 18.18kg / 40lbs. This makes the RP-1400CSW 49% heavier than the SuperSub X.
Here is a comparison of how RP-1400CSW and SuperSub X'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.
Klipsch RP-1400CSW needs about 29% more floor area. Klipsch RP-1400CSW stands 34mm further into the room. Klipsch RP-1400CSW is 120mm taller.

A sealed 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 X goes deeper - 12Hz against 15Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | GoldenEar SuperSub X has the bigger amplifier - 1400W against 500W RMS, about 4.5dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | Klipsch RP-1400CSW moves more air: 14" against 2 x 8" is 1.53x the cone area, not the 1.24x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | Klipsch RP-1400CSW is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; GoldenEar SuperSub X 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. |
| Wireless option | depends | Only Klipsch RP-1400CSW offers a wireless link (as a paid option). It decides where the sub can go if you cannot run a cable, and is worth nothing if you can. |
| Phase control | A | Klipsch RP-1400CSW has a phase control. Without one, the only way to fix a cancellation at the crossover is to move the box. |
| Driver placement | depends | Klipsch RP-1400CSW fires front and GoldenEar SuperSub X 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 X is about 43% 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 | Klipsch RP-1400CSW costs less - $1,100 against $1,499, about 27% less. |
A Klipsch RP-1400CSW B GoldenEar SuperSub X
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. Films or music? If this is mainly a home cinema, GoldenEar SuperSub X will hit harder for the money; if it is mainly for music in a normal-sized room, Klipsch RP-1400CSW is usually the easier one to make sound right. 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.
