In this review, we will be comparing QX-12SUB MKII and PB-1000, 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 PB-1000 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 Mission QX-12SUB MKIIand SVS PB-1000 have a single woofer setup however the Mission QX-12SUB MKII's woofer is 12-inch whereas the SVS PB-1000 features a 10-inch woofer.
Frequency Response
QX-12SUB MKII has a frequency range of 35-120 Hz whereas PB-1000 has a frequency range of 19-270 Hz. With a minimum frequency of 19Hz, the PB-1000 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
Both Mission QX-12SUB MKII and SVS PB-1000 have Bass Reflex type cabinets. 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 Mission QX-12SUB MKII's and SVS PB-1000'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 PB-1000 has external dimensions of 480.0 x 381.0 x 532.0mm (18-7/8 x 15 x 20-15/16inch).
Mission QX-12SUB MKII is 2mm shorter and 67mm less deeper than SVS PB-1000 but it is also 19mm wider.
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.
SVS PB-1000 needs about 9% more floor or shelf area. SVS PB-1000 is 67mm deeper, so it stands that much further out from the wall.
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 PB-1000 is approximately 2026.9cm2 / 314.2inch2. The QX-12SUB MKII requires 8% less surface area than the PB-1000 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 Mission QX-12SUB MKII weighs 23.00kg / 50.6lbs and the SVS PB-1000 weighs 20.91kg / 46lbs. This makes the QX-12SUB MKII 10% heavier than the PB-1000.
Here is a comparison of how QX-12SUB MKII and PB-1000's weights compare with the average, max and min weights in Powered Subwoofer class.

No single best subwoofer here. Your room, where the box can physically go, and whether this is mainly for films or mainly for music will settle it long before the specs do.
| Area | Better | Why |
|---|
| Bass depth | B | SVS PB-1000 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 | evenly matched | Much the same amplifier (300W vs 300W RMS) - under 1dB apart. |
| Driver area | A | Mission QX-12SUB MKII 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 | evenly matched | Both are ported designs, so they roll off in much the same way. |
| Price | B | SVS PB-1000 costs less - $499 against $699, about 29% less. |
A Mission QX-12SUB MKII B SVS PB-1000
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?
Neither runs away with it - they trade advantages. Let your room size and where the box can actually stand settle it.
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.
