In this review, we will be comparing LX-10SUB MKII and ProSub 1000, two Powered Subwoofer speakers from Mission and Definitive Technology. 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 LX-10SUB MKII and Definitive ProSub 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.Mission LX-10SUB MKIIand Definitive ProSub 1000 have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
LX-10SUB MKII has a frequency range of 40-200 Hz whereas ProSub 1000 has a frequency range of 18-150 Hz. With a minimum frequency of 18Hz, the ProSub 1000 can go significantly deeper on the low side and provide stronger bass compared to the LX-10SUB MKII's min frequency of 40Hz.
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 LX-10SUB 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 Definitive ProSub 1000 have Passive Radiator type enclosure. Passive Radiator type subwoofers sports a non-powered cone that moves in response to the main woofer to move air out in order to generate stronger bass in a smaller body compared to ported or 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 LX-10SUB MKII's and Definitive ProSub 1000's external dimensions. Mission LX-10SUB MKII has external dimensions of 447.0 x 312.0 x 407.0mm (17-5/8 x 12-5/16 x 16inch) whereas Definitive ProSub 1000 has external dimensions of 366.0 x 307.0 x 486.0mm (14-3/8 x 12-1/16 x 19-1/8inch).
Definitive ProSub 1000 is 5mm narrower and 81mm shorter than Mission LX-10SUB MKII but it is also 79mm 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.
Definitive ProSub 1000 needs about 17% more floor or shelf area. Definitive ProSub 1000 is 79mm deeper, so it stands that much further out from the wall. Mission LX-10SUB MKII is 81mm 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 LX-10SUB MKII is approximately 1269.8cm2 / 196.8inch2 and base area of the Definitive ProSub 1000 is approximately 1492.0cm2 / 231.3inch2. The LX-10SUB MKII requires 15% less surface area than the ProSub 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 LX-10SUB MKII weighs 16.00kg / 35.2lbs and the Definitive ProSub 1000 weighs 14.09kg / 31lbs. This makes the LX-10SUB MKII 14% heavier than the ProSub 1000.
Here is a comparison of how LX-10SUB MKII and ProSub 1000's weights compare with the average, max and min weights in Powered Subwoofer class.

A ported subwoofer against a passive radiator 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 | Definitive ProSub 1000 goes deeper - 18Hz against 40Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | Definitive ProSub 1000 has the bigger amplifier - 300W against 200W RMS, about 1.8dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | evenly matched | Near-identical radiating area (10" against 10"). |
| Enclosure | depends | Mission LX-10SUB MKII is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning; Definitive ProSub 1000 is passive radiator - a passive radiator behaves like a port without the pipe noise, and suits a slim cabinet. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Phase control | A | Mission LX-10SUB MKII has a phase control. Without one, the only way to fix a cancellation at the crossover is to move the box. |
| Price | evenly matched | Priced within a few per cent of each other. |
A Mission LX-10SUB MKII B Definitive ProSub 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?
Definitive ProSub 1000 has the edge on paper, though not by much. The "depends" rows are more likely to decide this than the score is.
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.
