In this review, we will be comparing Dynamo Foundation 12 and SB-1000 Pro, two Powered Subwoofer speakers from MartinLogan 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 MartinLogan Dynamo Foundation 12 and SVS SB-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.MartinLogan Dynamo Foundation 12and SVS SB-1000 Pro have the same driver set up: Both subwoofers have 1 x 12" drivers.
Frequency Response
Dynamo Foundation 12 has a frequency range of 24-200 Hz whereas SB-1000 Pro has a frequency range of 20-270 Hz. With a minimum frequency of 20Hz, the SB-1000 Pro can go slightly deeper then the Dynamo Foundation 12's min frequency of 24Hz.
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 12's and SVS SB-1000 Pro's external dimensions. MartinLogan Dynamo Foundation 12 has external dimensions of 404.8 x 357.2 x 408.0mm () whereas SVS SB-1000 Pro has external dimensions of 343.0 x 331.0 x 402.0mm (13-1/2inch x 13inch x 15-13/16inch).
MartinLogan Dynamo Foundation 12 is clearly the larger of the two speakers. Its body is 26.2mm wider, 61.8mm taller and 6mm deeper than SVS SB-1000 Pro.
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.
MartinLogan Dynamo Foundation 12 needs about 10% more floor or shelf area. MartinLogan Dynamo Foundation 12 is 62mm 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 12 is approximately 1457.4cm2 / 225.9inch2 and base area of the SVS SB-1000 Pro is approximately 1330.6cm2 / 206.2inch2. The Dynamo Foundation 12 requires 10% more surface area than the SB-1000 Pro 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 MartinLogan Dynamo Foundation 12 weighs 13.20kg / 29lbs and the SVS SB-1000 Pro weighs 11.82kg / 26lbs. This makes the Dynamo Foundation 12 12% heavier than the SB-1000 Pro.
Here is a comparison of how Dynamo Foundation 12 and SB-1000 Pro'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 SB-1000 Pro goes deeper - 20Hz against 24Hz. 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 (350W vs 325W RMS) - under 1dB apart. |
| Driver area | evenly matched | Near-identical radiating area (12" against 12"). |
| Enclosure | evenly matched | Both are sealed designs, so they roll off in much the same way. |
| Cabinet size | depends | SVS SB-1000 Pro is about 23% 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 SB-1000 Pro carries 5 years on parts against 3 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | B | SVS SB-1000 Pro costs less - $600 against $800, about 25% less. |
A MartinLogan Dynamo Foundation 12 B SVS SB-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 SB-1000 Pro is the easier recommendation: it leads on most of the measured areas and costs less. Take MartinLogan Dynamo Foundation 12 if one of the "depends" rows describes your room.
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.
