In this review, we will be comparing Kube 10 MIE and PB-1000 Pro, 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 Kube 10 MIE and SVS PB-1000 Pro 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 Kube 10 MIEand SVS PB-1000 Pro have a single woofer setup however the KEF Kube 10 MIE's woofer is 10-inch whereas the SVS PB-1000 Pro features a 12-inch woofer.
Frequency Response
Kube 10 MIE has a frequency range of 20-140 Hz whereas PB-1000 Pro has a frequency range of 17-260 Hz. With a minimum frequency of 17Hz, the PB-1000 Pro can go slightly deeper then the Kube 10 MIE'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.

Cabinet Type
The KEF Kube 10 MIE has a Acoustic Suspension type cabinet. 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. On the other hand the SVS PB-1000 Pro have Bass Reflex type enclosure. 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.
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 Kube 10 MIE's and SVS PB-1000 Pro's external dimensions. KEF Kube 10 MIE has external dimensions of 370 x 353 x 370 mm (14.6 x 13.9 x 14.6 in) whereas 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).
SVS PB-1000 Pro is clearly the larger of the two speakers. Its body is 27mm wider, 109mm taller and 139mm deeper than KEF Kube 10 MIE.
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 Kube 10 MIE is approximately 1306.1cm2 / 202.4inch2 and base area of the SVS PB-1000 Pro is approximately 1934.2cm2 / 299.8inch2. The Kube 10 MIE requires 32% less surface area than the PB-1000 Pro 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 Kube 10 MIE weighs 15.40kg / 33.9lbs and the SVS PB-1000 Pro weighs 19.30kg / 42.5lbs. This makes the PB-1000 Pro 25% heavier than the Kube 10 MIE.
Here is a comparison of how Kube 10 MIE and PB-1000 Pro'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 48% more floor area. SVS PB-1000 Pro stands 139mm further into the room. SVS PB-1000 Pro is 109mm taller.

A sealed subwoofer against a ported 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 | SVS PB-1000 Pro goes deeper - 17Hz 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 (300W vs 325W RMS) - under 1dB apart. |
| Driver area | B | SVS PB-1000 Pro moves more air: 12" against 10" is 1.44x the cone area, not the 1.2x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | KEF Kube 10 MIE is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; 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. 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). |
| Cabinet size | depends | KEF Kube 10 MIE is about 48% 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 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 | evenly matched | Priced within a few per cent of each other. |
A KEF Kube 10 MIE B SVS PB-1000 Pro
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?
SVS PB-1000 Pro 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, SVS PB-1000 Pro will hit harder for the money; if it is mainly for music in a normal-sized room, KEF Kube 10 MIE is usually the easier one to make sound right. If placement is the constraint - a corner, behind a sofa, under a desk - KEF Kube 10 MIE 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.
