In this review, we will be comparing Dynamo Foundation 10 and SPL-100, two Powered Subwoofer speakers from MartinLogan and Klipsch. 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 Klipsch SPL-100 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 Klipsch SPL-100 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 SPL-100 has a frequency range of 27-125 Hz. With a minimum frequency of 25Hz, the Dynamo Foundation 10 can go slightly deeper then the SPL-100's min frequency of 27Hz.
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 Klipsch SPL-100's external dimensions. MartinLogan Dynamo Foundation 10 has external dimensions of 328.6 x 314.3 x 369.9mm () whereas Klipsch SPL-100 has external dimensions of 418.0 x 358.0 x 478.0mm (16-7/16 x 14-1/16 x 18-13/16inch).
Klipsch SPL-100 is clearly the larger of the two speakers. Its body is 43.7mm wider, 89.4mm taller and 108.1mm deeper than MartinLogan Dynamo Foundation 10.
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.
Klipsch SPL-100 needs about 47% more floor or shelf area. Klipsch SPL-100 is 108mm deeper, so it stands that much further out from the wall. Klipsch SPL-100 is 89mm 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 Klipsch SPL-100 is approximately 1711.2cm2 / 265.2inch2. The Dynamo Foundation 10 requires 32% less surface area than the SPL-100 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 Klipsch SPL-100 weighs 16.82kg / 37lbs. This makes the SPL-100 56% heavier than the Dynamo Foundation 10.
Here is a comparison of how Dynamo Foundation 10 and SPL-100's weights compare with the average, max and min weights in Powered Subwoofer class.

A sealed subwoofer against a ported 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 | evenly matched | Effectively the same reach (25Hz vs 27Hz). |
| Amplifier power | evenly matched | Much the same amplifier (200W vs 200W RMS) - under 1dB apart. |
| 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; Klipsch SPL-100 is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning. 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 47% 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 | A | MartinLogan Dynamo Foundation 10 carries 3 years on parts against 2 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | B | Klipsch SPL-100 costs less - $399 against $600, about 34% less. |
A MartinLogan Dynamo Foundation 10 B Klipsch SPL-100
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?
MartinLogan Dynamo Foundation 10 is ahead, but on only 1 of the measured areas, and it costs about 50% more. Klipsch SPL-100 is the sensible buy unless your room is large enough to need the extra. Films or music? If this is mainly a home cinema, Klipsch SPL-100 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.
