In this review, we will be comparing PC13-Ultra and ForceField 4, two Powered Subwoofer speakers from SVS 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 SVS PC13-Ultra and GoldenEar ForceField 4 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 SVS PC13-Ultraand GoldenEar ForceField 4 have a single woofer setup however the SVS PC13-Ultra's woofer is 13.5-inch whereas the GoldenEar ForceField 4 features a 10-inch woofer.
Frequency Response
PC13-Ultra has a frequency range of 15-200 Hz whereas ForceField 4 has a frequency range of 14-250 Hz. With a minimum frequency of 14Hz, the ForceField 4 can go slightly deeper then the PC13-Ultra'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 SVS PC13-Ultra has a Bass Reflex type cabinet. 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. On the other hand the GoldenEar ForceField 4 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 SVS PC13-Ultra's and GoldenEar ForceField 4's external dimensions. SVS PC13-Ultra has external dimensions of 1194.0 x 422.0 x 422.0mm (47 x 16-5/8 x 16-5/8inch) whereas GoldenEar ForceField 4 has external dimensions of 331.0 x 340.0 x 482.0mm (13inch x 13-3/8inch x 18-15/16inch).
GoldenEar ForceField 4 is 82mm narrower and 863mm shorter than SVS PC13-Ultra but it is also 60mm deeper.
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.
SVS PC13-Ultra needs about 9% more floor or shelf area. GoldenEar ForceField 4 is 60mm deeper, so it stands that much further out from the wall. SVS PC13-Ultra is 863mm taller.
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 SVS PC13-Ultra is approximately 1780.8cm2 / 276.0inch2 and base area of the GoldenEar ForceField 4 is approximately 1638.8cm2 / 254.0inch2. The PC13-Ultra requires 9% more surface area than the ForceField 4 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 SVS PC13-Ultra weighs 40.80kg / 89.8lbs and the GoldenEar ForceField 4 weighs 14.55kg / 32lbs. This makes the PC13-Ultra 180% heavier than the ForceField 4.
Here is a comparison of how PC13-Ultra and ForceField 4's weights compare with the average, max and min weights in Powered Subwoofer class.

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 | evenly matched | Effectively the same reach (15Hz vs 14Hz). |
| Amplifier power | evenly matched | Much the same amplifier (1000W vs 1200W RMS) - under 1dB apart. |
| Driver area | A | SVS PC13-Ultra moves more air: 13.5" against 10" is 1.82x the cone area, not the 1.35x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | SVS PC13-Ultra is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning; GoldenEar ForceField 4 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. |
| Phase control | A | SVS PC13-Ultra has a phase control. Without one, the only way to fix a cancellation at the crossover is to move the box. |
| Cabinet size | depends | GoldenEar ForceField 4 is about 74% 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 | SVS PC13-Ultra carries 5 years on parts against 3 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | B | GoldenEar ForceField 4 costs less - $799 against $1,700, about 53% less. |
A SVS PC13-Ultra B GoldenEar ForceField 4
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: SVS PC13-Ultra measures better, GoldenEar ForceField 4 costs about 53% 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 $799 each, two GoldenEar ForceField 4 cost about $1,598 against $1,700 for one of the other, which is worth a thought. If placement is the constraint - a corner, behind a sofa, under a desk - GoldenEar ForceField 4 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.
