In this review, we will be comparing Dynamo 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 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 10and Klipsch SPL-100 have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
Dynamo 10 has a frequency range of 23-200 Hz whereas SPL-100 has a frequency range of 27-125 Hz. With a minimum frequency of 23Hz, the Dynamo 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 10's and Klipsch SPL-100's external dimensions. MartinLogan Dynamo 10 has external dimensions of 373.1 x 349.3 x 404.8mm () 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 8.7mm wider, 44.9mm taller and 73.2mm deeper than MartinLogan Dynamo 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 21% more floor or shelf area. Klipsch SPL-100 is 73mm deeper, so it stands that much further out from the wall. Klipsch SPL-100 is 45mm 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 10 is approximately 1414.0cm2 / 219.2inch2 and base area of the Klipsch SPL-100 is approximately 1711.2cm2 / 265.2inch2. The Dynamo 10 requires 17% 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 10 weighs 19.41kg / 42.7lbs and the Klipsch SPL-100 weighs 16.82kg / 37lbs. This makes the Dynamo 10 15% heavier than the SPL-100.
Here is a comparison of how Dynamo 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 | A | MartinLogan Dynamo 10 goes deeper - 23Hz against 27Hz. A real difference, though most music has little content below 27Hz. |
| Amplifier power | A | MartinLogan Dynamo 10 has the bigger amplifier - 500W against 200W RMS, about 4dB 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 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 10 is about 26% 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 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 $1,200, about 67% less. |
A MartinLogan Dynamo 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?
The usual trade-off: MartinLogan Dynamo 10 measures better, Klipsch SPL-100 costs about 67% less. In a normal room, placement will make a bigger difference than the gap between these two. 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 10 is usually the easier one to make sound right. Two small subwoofers beat one big one in most rooms - a pair evens out the room modes in a way no single box can, whatever its specs. At $399 each, two Klipsch SPL-100 cost about $798 against $1,200 for one of the other, which is worth a thought.
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.
