In this review, we will be comparing SuperSub XXL and SPL-100, two Powered Subwoofer speakers from GoldenEar and Klipsch. 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 XXL and Klipsch SPL-100 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 XXL and Klipsch SPL-100 have a totally different setup: the GoldenEar SuperSub XXL features 2 x 12-inch drivers whereas the SPL-100 features 1 x 10-inch drivers.
Frequency Response
SuperSub XXL has a frequency range of 10-250 Hz whereas SPL-100 has a frequency range of 27-125 Hz. With a minimum frequency of 10Hz, the SuperSub XXL can go significantly deeper on the low side and provide stronger bass compared to the SPL-100'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 GoldenEar SuperSub XXL 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 Klipsch SPL-100 have Bass Reflex type enclosure. Bass Reflex type subwoofers (aka Ported, Vented or Reflex Port) have enclosures that uses a port, hole or vent cut into the cabinet. Ported designs are generally more efficient than the 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 XXL's and Klipsch SPL-100's external dimensions. GoldenEar SuperSub XXL has external dimensions of 447.0 x 485.0 x 434.0mm (17-9/16inch x 19-1/16inch x 17-1/16inch) whereas Klipsch SPL-100 has external dimensions of 418.0 x 358.0 x 478.0mm (16-7/16 x 14-1/16 x 18-13/16inch).
Klipsch SPL-100 is 127mm narrower and 29mm shorter than GoldenEar SuperSub XXL but it is also 44mm deeper.

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 XXL is approximately 2104.9cm2 / 326.3inch2 and base area of the Klipsch SPL-100 is approximately 1711.2cm2 / 265.2inch2. The SuperSub XXL requires 23% more surface area than the SPL-100 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 GoldenEar SuperSub XXL weighs 37.27kg / 82lbs and the Klipsch SPL-100 weighs 16.82kg / 37lbs. This makes the SuperSub XXL 122% heavier than the SPL-100.
Here is a comparison of how SuperSub XXL and SPL-100'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.
GoldenEar SuperSub XXL needs about 23% more floor area. Klipsch SPL-100 stands 44mm further into the room. GoldenEar SuperSub XXL is 29mm taller.

A passive radiator subwoofer against a ported 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 | A | GoldenEar SuperSub XXL goes deeper - 10Hz against 27Hz. 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 XXL has the bigger amplifier - 1600W against 200W RMS, about 9dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | GoldenEar SuperSub XXL moves more air: 2 x 12" against 10" is 2.88x the cone area, not the 1.7x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | GoldenEar SuperSub XXL is passive radiator - a passive radiator behaves like a port without the pipe noise, and suits a slim cabinet; Klipsch SPL-100 is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning. 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 SPL-100 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 | B | Klipsch SPL-100 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 XXL fires side and Klipsch SPL-100 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 | Klipsch SPL-100 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. |
| Warranty | A | GoldenEar SuperSub XXL carries 3 years on parts against 2 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | B | Klipsch SPL-100 costs less - $399 against $2,499, about 84% less. |
A GoldenEar SuperSub XXL B Klipsch SPL-100
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: GoldenEar SuperSub XXL measures better, Klipsch SPL-100 costs about 84% 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 $399 each, two Klipsch SPL-100 cost about $798 against $2,499 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.
