In this review, we will be comparing KC62 and 3000 Micro, two Powered Subwoofer speakers from KEF and SVS. 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 KEF KC62 and SVS 3000 Micro 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 KEF KC62and SVS 3000 Micro have a double woofer setup however the KEF KC62's woofer is 6.5-inch whereas the SVS 3000 Micro features a 8-inch woofer.
Frequency Response
KC62 has a frequency range of 11-200 Hz whereas 3000 Micro has a frequency range of 23-240 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's min frequency of 23Hz.
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
Both KEF KC62 and SVS 3000 Micro have Acoustic Suspension type cabinets. 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 KEF KC62's and SVS 3000 Micro's external dimensions. 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) whereas SVS 3000 Micro has external dimensions of 277.0 x 297.0 x 310.0mm (10-7/8inch x 11-11/16inch x 12-3/16inch).
SVS 3000 Micro is clearly the larger of the two speakers. Its body is 39mm wider, 32mm taller and 29mm 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 KEF KC62 is approximately 725.0cm2 / 112.4inch2 and base area of the SVS 3000 Micro is approximately 920.7cm2 / 142.7inch2. The KC62 requires 21% less surface area than the 3000 Micro which gives it a small advantage 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 KEF KC62 weighs 14.05kg / 30.9lbs and the SVS 3000 Micro weighs 10.23kg / 22.5lbs. This makes the KC62 37% heavier than the 3000 Micro.
Here is a comparison of how KC62 and 3000 Micro's weights compare with the average, max and min weights in Powered Subwoofer class.

Different price classes - KEF KC62 costs roughly 1.7x what SVS 3000 Micro does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | A | KEF KC62 goes deeper - 11Hz against 23Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | A | KEF KC62 has the bigger amplifier - 1000W against 800W RMS, about 1dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | SVS 3000 Micro moves more air: 2 x 8" against 2 x 6.5" is 1.51x the cone area, not the 1.23x 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 and onboard DSP). |
| Speaker-level inputs | A | 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. |
| Cabinet size | depends | KEF KC62 is about 30% 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 | B | SVS 3000 Micro 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 | B | SVS 3000 Micro costs less - $900 against $1,500, about 40% less. |
A KEF KC62 B SVS 3000 Micro
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?
KEF KC62 is ahead, but on only 1 of the measured areas, and it costs about 67% more. SVS 3000 Micro is the sensible buy unless your room is large enough to need the extra. 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. 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 $900 each, two SVS 3000 Micro cost about $1,800 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.
