Our take on the Yamaha NS-SW050BL

The Yamaha NS-SW050 is a compact 8-inch powered subwoofer rated at 50 W continuous (100 W dynamic) with a bass-reflex cabinet. It uses Yamaha's Advanced YST servo technology and a Twisted Flare Port to tighten low-end output down to a claimed 28 Hz. It is a small, single-RCA-input sub meant to add weight to a stereo or small home theater setup. The best new price is $219.95 at Walmart as of November 5, 2026, with 5 stores listing it new.

Questions and answers

Is the Yamaha NS-SW050 worth it for a small room?
Yes, for a bedroom, office or small living room it adds noticeable bass without taking much space. In a large open room it will run out of output.
Does it work with a soundbar?
Only if the soundbar has a subwoofer output. The NS-SW050 takes a single RCA input, so a soundbar without a sub-out cannot feed it.
How low does it go?
Yamaha rates it to 28 Hz, though real output at that frequency is modest given the 50 W amplifier and 8-inch driver.
What is in the box?
The subwoofer and power cord. You supply the RCA subwoofer cable and the settings on your receiver or amp.
When is it cheapest?
The best new price seen is $219.95 at Walmart as of November 5, 2026. Entry-level subs like this usually dip during holiday sales.
