In this review, we will be comparing PB-1000 Pro and KC62, two Powered Subwoofer speakers from SVS and KEF. 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 PB-1000 Pro and KEF KC62 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.SVS PB-1000 Pro and KEF KC62 have a totally different setup: the SVS PB-1000 Pro features 1 x 12-inch drivers whereas the KC62 features 2 x 6.5-inch drivers.
Frequency Response
PB-1000 Pro has a frequency range of 17-260 Hz whereas KC62 has a frequency range of 11-200 Hz. With a minimum frequency of 11Hz, the KC62 can go significantly deeper on the low side and provide stronger bass compared to the PB-1000 Pro's min frequency of 17Hz.
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 PB-1000 Pro 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 KEF KC62 have Acoustic Suspension type enclosure. 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.
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 PB-1000 Pro's and KEF KC62's external dimensions. SVS PB-1000 Pro has external dimensions of 479.0 x 380.0 x 509.0mm (18-13/16inch x 15inch x 20-15/16inch) whereas KEF KC62 has external dimensions of 245.0 x 258.0 x 281.0mm (9-5/8inch x 10-1/8inch x 11-1/16inch).
SVS PB-1000 Pro is clearly the larger of the two speakers. Its body is 122mm wider, 234mm taller and 228mm deeper than KEF KC62.
Below you can see the front view size comparison of SVS PB-1000 Pro and KEF KC62 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 SVS PB-1000 Pro is approximately 1934.2cm2 / 299.8inch2 and base area of the KEF KC62 is approximately 725.0cm2 / 112.4inch2. The PB-1000 Pro requires 167% more surface area than the KC62 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 PB-1000 Pro weighs 19.30kg / 42.5lbs and the KEF KC62 weighs 14.05kg / 30.9lbs. This makes the PB-1000 Pro 37% heavier than the KC62.
Here is a comparison of how PB-1000 Pro and KC62'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.
SVS PB-1000 Pro needs about 167% more floor area. SVS PB-1000 Pro stands 228mm further into the room. SVS PB-1000 Pro is 234mm taller.

A ported subwoofer against a sealed 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 | KEF KC62 goes deeper - 11Hz against 17Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | KEF KC62 has the bigger amplifier - 1000W against 325W RMS, about 4.9dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | SVS PB-1000 Pro moves more air: 12" against 2 x 6.5" is 1.7x the cone area, not the 1.31x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | SVS PB-1000 Pro is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning; KEF KC62 is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Setup and tuning | evenly matched | The same tuning tools on both (room correction and onboard DSP). |
| Driver placement | depends | SVS PB-1000 Pro fires front and KEF KC62 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 | KEF KC62 is about 81% 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 PB-1000 Pro carries 5 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 | A | SVS PB-1000 Pro costs less - $799 against $1,500, about 47% less. |
A SVS PB-1000 Pro B KEF KC62
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, SVS PB-1000 Pro will hit harder for the money; if it is mainly for music in a normal-sized room, KEF KC62 is usually the easier one to make sound right. 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 SVS PB-1000 Pro cost about $1,598 against $1,500 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.
