In this review, we will be comparing Daedalus DS8 Class D 8" Powered Subwoofer and KUBE 8b, 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 DS8 Class D 8" Powered Subwoofer and KEF KUBE 8b 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 DS8 Class D 8" Powered Subwooferand KEF KUBE 8b have the same driver set up: Both subwoofers have 1 x 8" drivers.
Frequency Response
Daedalus DS8 Class D 8" Powered Subwoofer has a frequency range of 24-195 Hz whereas KUBE 8b has a frequency range of 34-140 Hz. With a minimum frequency of 24Hz, the Daedalus DS8 Class D 8" Powered Subwoofer can go significantly deeper on the low side and provide stronger bass compared to the KUBE 8b's min frequency of 34Hz.
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 DS8 Class D 8" 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 KUBE 8b 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 DS8 Class D 8" Powered Subwoofer's and KEF KUBE 8b's external dimensions. Aperion Daedalus DS8 Class D 8" Powered Subwoofer has external dimensions of 330.2 x 279.4 x 309.9mm (13 x 11 x 12.2inch) whereas KEF KUBE 8b has external dimensions of 294.0 x 296.0 x 339.0mm (11-9/16 x 11-5/8 x 13-5/16inch).
Aperion Daedalus DS8 Class D 8" Powered Subwoofer is 16.6mm narrower and 29.1mm less deeper than KEF KUBE 8b but it is also 36.2mm taller.
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.
KEF KUBE 8b needs about 16% more floor or shelf area. KEF KUBE 8b is 29mm deeper, so it stands that much further out from the wall. Aperion Daedalus DS8 Class D 8" Powered Subwoofer is 36mm 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 DS8 Class D 8" Powered Subwoofer is approximately 865.9cm2 / 134.2inch2 and base area of the KEF KUBE 8b is approximately 1003.4cm2 / 155.5inch2. The Daedalus DS8 Class D 8" Powered Subwoofer requires 14% less surface area than the KUBE 8b 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 Aperion Daedalus DS8 Class D 8" Powered Subwoofer weighs 12.25kg / 27lbs and the KEF KUBE 8b weighs 11.36kg / 25lbs. This makes the Daedalus DS8 Class D 8" Powered Subwoofer 8% heavier than the KUBE 8b.
Here is a comparison of how Daedalus DS8 Class D 8" Powered Subwoofer and KUBE 8b'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 | A | Aperion Daedalus DS8 Class D 8" Powered Subwoofer goes deeper - 24Hz against 34Hz. That gap covers the lowest notes of a five-string bass and a concert bass drum. |
| Amplifier power | evenly matched | Much the same amplifier (250W vs 300W RMS) - under 1dB apart. |
| Driver area | evenly matched | Near-identical radiating area (8" against 8"). |
| Enclosure | depends | Aperion Daedalus DS8 Class D 8" 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 KUBE 8b 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. |
| Price | A | Aperion Daedalus DS8 Class D 8" Powered Subwoofer costs less - $499 against $600, about 17% less. |
A Aperion Daedalus DS8 Class D 8" Powered Subwoofer B KEF KUBE 8b
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?
Aperion Daedalus DS8 Class D 8" Powered Subwoofer has the edge on paper, though not by much. The "depends" rows are more likely to decide this than the score is. Films or music? If this is mainly a home cinema, Aperion Daedalus DS8 Class D 8" Powered Subwoofer will hit harder for the money; if it is mainly for music in a normal-sized room, KEF KUBE 8b is usually the easier one to make sound right.
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.
