In this review, we will be comparing 3000 Micro R Evolution 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 3000 Micro R Evolution 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.Both SVS 3000 Micro R Evolutionand KEF KC62 have a double woofer setup however the SVS 3000 Micro R Evolution's woofer is 9-inch whereas the KEF KC62 features a 6.5-inch woofer.
Frequency Response
3000 Micro R Evolution has a frequency range of 20-230 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 3000 Micro R Evolution'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.

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 3000 Micro R Evolution's and KEF KC62's external dimensions. SVS 3000 Micro R Evolution has external dimensions of 277.8 x 301.0 x 313.0mm () 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 3000 Micro R Evolution is clearly the larger of the two speakers. Its body is 43mm wider, 32.8mm taller and 32mm deeper than KEF KC62.
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 3000 Micro R Evolution is approximately 942.1cm2 / 146.0inch2 and base area of the KEF KC62 is approximately 725.0cm2 / 112.4inch2. The 3000 Micro R Evolution requires 30% 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 3000 Micro R Evolution weighs 10.23kg / 22.5lbs and the KEF KC62 weighs 14.05kg / 30.9lbs. This makes the KC62 37% heavier than the 3000 Micro R Evolution.
Here is a comparison of how 3000 Micro R Evolution 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 3000 Micro R Evolution needs about 30% more floor area. SVS 3000 Micro R Evolution stands 32mm further into the room. SVS 3000 Micro R Evolution is 33mm taller.

Two quite different sizes of subwoofer. Room volume decides this more than anything else on the page: a big driver in a small room is wasted, and a small one in a large room is worked to death.
| Area | Better | Why |
|---|
| Bass depth | B | KEF KC62 goes deeper - 11Hz against 20Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | evenly matched | Much the same amplifier (1200W vs 1000W RMS) - under 1dB apart. |
| Driver area | A | SVS 3000 Micro R Evolution moves more air: 2 x 9" against 2 x 6.5" is 1.92x the cone area, not the 1.38x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | evenly matched | Both are sealed designs, so they roll off in much the same way. |
| Setup and tuning | evenly matched | The same tuning tools on both (room correction). |
| Speaker-level inputs | B | KEF KC62 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. |
| Wireless option | depends | Only KEF KC62 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. |
| Driver placement | depends | SVS 3000 Micro R Evolution fires side-firing 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 32% 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 3000 Micro R Evolution 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 3000 Micro R Evolution costs less - $999 against $1,500, about 33% less. |
A SVS 3000 Micro R Evolution 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. Check your amplifier first: if it has no subwoofer or preamp output, KEF KC62 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 - KEF KC62 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.
