In this review, we will be comparing Dynamo Foundation 10 and ProSub 1000, two Powered Subwoofer speakers from MartinLogan 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 MartinLogan Dynamo Foundation 10 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.MartinLogan Dynamo Foundation 10and Definitive ProSub 1000 have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
Dynamo Foundation 10 has a frequency range of 25-200 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 Dynamo Foundation 10's min frequency of 25Hz.
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.

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 MartinLogan Dynamo Foundation 10's and Definitive ProSub 1000's external dimensions. MartinLogan Dynamo Foundation 10 has external dimensions of 328.6 x 314.3 x 369.9mm () 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).
MartinLogan Dynamo Foundation 10 is 37.4mm shorter and 116.1mm less deeper than Definitive ProSub 1000 but it is also 7.3mm 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.
Definitive ProSub 1000 needs about 28% more floor or shelf area. Definitive ProSub 1000 is 116mm deeper, so it stands that much further out from the wall. Definitive ProSub 1000 is 37mm 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 MartinLogan Dynamo Foundation 10 is approximately 1162.6cm2 / 180.2inch2 and base area of the Definitive ProSub 1000 is approximately 1492.0cm2 / 231.3inch2. The Dynamo Foundation 10 requires 22% 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 MartinLogan Dynamo Foundation 10 weighs 10.80kg / 23.8lbs and the Definitive ProSub 1000 weighs 14.09kg / 31lbs. This makes the ProSub 1000 30% heavier than the Dynamo Foundation 10.
Here is a comparison of how Dynamo Foundation 10 and ProSub 1000's weights compare with the average, max and min weights in Powered Subwoofer class.

A sealed 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 25Hz. 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 | MartinLogan Dynamo Foundation 10 is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; 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. |
| Cabinet size | depends | MartinLogan Dynamo Foundation 10 is about 30% 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 | Definitive ProSub 1000 costs less - $499 against $600, about 17% less. |
A MartinLogan Dynamo Foundation 10 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 is the easier recommendation: it leads on most of the measured areas and costs less. Take MartinLogan Dynamo Foundation 10 if one of the "depends" rows describes your room. Films or music? If this is mainly a home cinema, Definitive ProSub 1000 will hit harder for the money; if it is mainly for music in a normal-sized room, MartinLogan Dynamo Foundation 10 is usually the easier one to make sound right. If placement is the constraint - a corner, behind a sofa, under a desk - MartinLogan Dynamo Foundation 10 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.
