In this review, we will be comparing Daedalus DS15 Class D 15" Powered Subwoofer and KC62, two Powered Subwoofer speakers from Aperion 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 Aperion Daedalus DS15 Class D 15" Powered Subwoofer 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.Aperion Daedalus DS15 Class D 15" Powered Subwoofer and KEF KC62 have a totally different setup: the Aperion Daedalus DS15 Class D 15" Powered Subwoofer features 1 x 15-inch drivers whereas the KC62 features 2 x 6.5-inch drivers.
Frequency Response
Daedalus DS15 Class D 15" Powered Subwoofer has a frequency range of 18-195 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 Daedalus DS15 Class D 15" Powered Subwoofer's min frequency of 18Hz.
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 Aperion Daedalus DS15 Class D 15" Powered Subwoofer 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 Aperion Daedalus DS15 Class D 15" Powered Subwoofer's and KEF KC62's external dimensions. Aperion Daedalus DS15 Class D 15" Powered Subwoofer has external dimensions of 569.0 x 469.9 x 551.2mm (22.4 x 18.5 x 21.7inch) 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).
Aperion Daedalus DS15 Class D 15" Powered Subwoofer is clearly the larger of the two speakers. Its body is 211.9mm wider, 324mm taller and 270.2mm deeper than KEF KC62.
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.
Aperion Daedalus DS15 Class D 15" Powered Subwoofer needs about 257% more floor or shelf area. Aperion Daedalus DS15 Class D 15" Powered Subwoofer is 270mm deeper, so it stands that much further out from the wall. Aperion Daedalus DS15 Class D 15" Powered Subwoofer is 324mm 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 Aperion Daedalus DS15 Class D 15" Powered Subwoofer is approximately 2590.1cm2 / 401.5inch2 and base area of the KEF KC62 is approximately 725.0cm2 / 112.4inch2. The Daedalus DS15 Class D 15" Powered Subwoofer requires 257% 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 Aperion Daedalus DS15 Class D 15" Powered Subwoofer weighs 35.38kg / 77.8lbs and the KEF KC62 weighs 14.05kg / 30.9lbs. This makes the Daedalus DS15 Class D 15" Powered Subwoofer 152% heavier than the KC62.
Here is a comparison of how Daedalus DS15 Class D 15" Powered Subwoofer and KC62's weights compare with the average, max and min weights in Powered Subwoofer class.

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 18Hz. 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 550W RMS, about 2.6dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | Aperion Daedalus DS15 Class D 15" Powered Subwoofer moves more air: 15" against 2 x 6.5" is 2.66x the cone area, not the 1.63x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | Aperion Daedalus DS15 Class D 15" Powered Subwoofer 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. |
| Driver placement | depends | Aperion Daedalus DS15 Class D 15" Powered Subwoofer 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 88% 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. |
| Price | A | Aperion Daedalus DS15 Class D 15" Powered Subwoofer costs less - $1,199 against $1,500, about 20% less. |
A Aperion Daedalus DS15 Class D 15" Powered Subwoofer 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?
The usual trade-off: KEF KC62 measures better, Aperion Daedalus DS15 Class D 15" Powered Subwoofer costs about 20% less. In a normal room, placement will make a bigger difference than the gap between these two. Films or music? If this is mainly a home cinema, Aperion Daedalus DS15 Class D 15" Powered Subwoofer 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. 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.
