In this review, we will be comparing NS-SW100 and NS-SW050, two Powered Subwoofer speakers by Yamaha. 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 Yamaha NS-SW050 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.Both Yamaha NS-SW100and Yamaha NS-SW050 have a single woofer setup however the Yamaha NS-SW100's woofer is 10-inch whereas the Yamaha NS-SW050 features a 8-inch woofer.
Frequency Response
NS-SW100 has a frequency range of 25-180 Hz whereas NS-SW050 has a frequency range of 28-200 Hz. With a minimum frequency of 25Hz, the NS-SW100 can go slightly deeper then the NS-SW050's min frequency of 28Hz.
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 Yamaha NS-SW050 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 Yamaha NS-SW050'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 Yamaha NS-SW050 has external dimensions of 292.1 x 292.1 x 339.7mm (11.5 x 11.5 x 13.375inch).
Yamaha NS-SW100 is clearly the larger of the two speakers. Its body is 60.3mm wider, 60.3mm taller and 69.9mm deeper than Yamaha NS-SW050.
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 Yamaha NS-SW050 is approximately 992.3cm2 / 153.8inch2. The NS-SW100 requires 45% more surface area than the NS-SW050 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 Yamaha NS-SW100 weighs 12.02kg / 26.4lbs and the Yamaha NS-SW050 weighs 8.48kg / 18.7lbs. This makes the NS-SW100 42% heavier than the NS-SW050.
Here is a comparison of how NS-SW100 and NS-SW050's weights compare with the average, max and min weights in Powered Subwoofer class.
