In this review, we will be comparing QX-12SUB MKII and SB-2000, two Powered Subwoofer speakers from Mission 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 Mission QX-12SUB MKII and SVS SB-2000 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.Mission QX-12SUB MKIIand SVS SB-2000 have the same driver set up: Both subwoofers have 1 x 12" drivers.
Frequency Response
QX-12SUB MKII has a frequency range of 35-120 Hz whereas SB-2000 has a frequency range of 19-220 Hz. With a minimum frequency of 19Hz, the SB-2000 can go significantly deeper on the low side and provide stronger bass compared to the QX-12SUB MKII's min frequency of 35Hz.
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 Mission QX-12SUB MKII 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 SVS SB-2000 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 Mission QX-12SUB MKII's and SVS SB-2000's external dimensions. Mission QX-12SUB MKII has external dimensions of 478.0 x 400.0 x 465.0mm (18-13/16 x 15-3/4 x 18-5/16inch) whereas SVS SB-2000 has external dimensions of 372.0 x 362.0 x 478.0mm (14-5/8 x 14-1/4 x 18-13/16inch).
SVS SB-2000 is 38mm narrower and 106mm shorter than Mission QX-12SUB MKII but it is also 13mm deeper.
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.
Near-identical footprints. Mission QX-12SUB MKII is 106mm 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 Mission QX-12SUB MKII is approximately 1860.0cm2 / 288.3inch2 and base area of the SVS SB-2000 is approximately 1730.4cm2 / 268.2inch2. The QX-12SUB MKII requires 7% more surface area than the SB-2000 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 Mission QX-12SUB MKII weighs 23.00kg / 50.6lbs and the SVS SB-2000 weighs 15.82kg / 34.8lbs. This makes the QX-12SUB MKII 45% heavier than the SB-2000.
Here is a comparison of how QX-12SUB MKII and SB-2000'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 | SVS SB-2000 goes deeper - 19Hz against 35Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | SVS SB-2000 has the bigger amplifier - 500W against 300W RMS, about 2.2dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | evenly matched | Near-identical radiating area (12" against 12"). |
| Enclosure | depends | Mission QX-12SUB MKII is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning; SVS SB-2000 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. |
| Cabinet size | depends | SVS SB-2000 is about 28% 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 | B | SVS SB-2000 costs less - $600 against $699, about 14% less. |
A Mission QX-12SUB MKII B SVS SB-2000
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 SB-2000 is the easier recommendation: it leads on most of the measured areas and costs less. Take Mission QX-12SUB MKII if one of the "depends" rows describes your room. Films or music? If this is mainly a home cinema, Mission QX-12SUB MKII will hit harder for the money; if it is mainly for music in a normal-sized room, SVS SB-2000 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.
