In this review, we will be comparing NS-SW100 and R-101SW, two Powered Subwoofer speakers from Yamaha 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 Yamaha NS-SW100 and Klipsch R-101SW 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.Yamaha NS-SW100and Klipsch R-101SW have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
NS-SW100 has a frequency range of 25-180 Hz whereas R-101SW has a frequency range of 29.5-160 Hz. With a minimum frequency of 25Hz, the NS-SW100 can go significantly deeper on the low side and provide stronger bass compared to the R-101SW's min frequency of 30Hz.
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
Both Yamaha NS-SW100 and Klipsch R-101SW have Bass Reflex type cabinets. 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.
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 Yamaha NS-SW100's and Klipsch R-101SW's external dimensions. Yamaha NS-SW100 has external dimensions of 352.4 x 352.4 x 409.6mm (13.875 x 13.875 x 16.125inch) whereas Klipsch R-101SW has external dimensions of 370.0 x 358.0 x 529.0mm (14-9/16inch x 14-1/16inch x 20-13/16inch).
Klipsch R-101SW is clearly the larger of the two speakers. Its body is 5.6mm wider, 17.6mm taller and 119.4mm deeper than Yamaha NS-SW100.
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 R-101SW needs about 31% more floor or shelf area. Klipsch R-101SW is 119mm deeper, so it stands that much further out from the wall. Klipsch R-101SW is 18mm 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 Yamaha NS-SW100 is approximately 1443.4cm2 / 223.7inch2 and base area of the Klipsch R-101SW is approximately 1893.8cm2 / 293.5inch2. The NS-SW100 requires 24% less surface area than the R-101SW 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 Yamaha NS-SW100 weighs 12.02kg / 26.4lbs and the Klipsch R-101SW weighs 13.91kg / 30.6lbs. This makes the R-101SW 16% heavier than the NS-SW100.
Here is a comparison of how NS-SW100 and R-101SW's weights compare with the average, max and min weights in Powered Subwoofer class.

Different price classes - Klipsch R-101SW costs roughly 1.8x what Yamaha NS-SW100 does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | A | Yamaha NS-SW100 goes deeper - 25Hz against 30Hz. That gap covers the lowest notes of a five-string bass and a concert bass drum. |
| Amplifier power | B | Klipsch R-101SW has the bigger amplifier - 150W against 50W RMS, about 4.8dB 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 | evenly matched | Both are ported designs, so they roll off in much the same way. |
| Cabinet size | depends | Yamaha NS-SW100 is about 27% 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 | A | Yamaha NS-SW100 costs less - $270 against $499, about 46% less. |
A Yamaha NS-SW100 B Klipsch R-101SW
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?
Neither runs away with it - they trade advantages. Let your room size and where the box can actually stand settle it. 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 $270 each, two Yamaha NS-SW100 cost about $540 against $499 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.
