Plug and play for dynamic sound where and
when you want it.The most powerful portable
speaker for office or home.
Conv enience AND pow er!
A speaker that plugs into your computer’s USB port
is really convenient. But ordinary USB speakers
can’t deliver much power: only 0.5W x 2. Yamaha
solves that problem with the NX-U10. It can output
max. 10W x 2 — 20 times as much power! Your
music will sound great, and you can even use it for
business presentations in large rooms.
Bass with a punch
Along with the expansive power, you get strong,
rich bass. The NX-U10 includes SR-Bass™ (Swing
Radiator Bass) technology, so music, games and
even movies sound just as dynamic
as they are supposed to.

Handy and versatile
Connecting the NX-U10 to your laptop or other computer is
quick and easy. You only use one USB cable — no need
for a power cord. Or you can power it from an AC outlet
or four AAA batteries. It also has a stereo mini jack, so you
can plug in your iPod, game console or other portable
device to enjoy bigger, better sound.

How does it work?
PowerStorage™ Circuit
If music varies in loudness or includes rests, its signal level is not constant.
The power used to play music is an average of about 1/8 of the amount
that is supplied. The remaining 7/8 of the power is unused. The
PowerStorage Circuit
stores this unused
electric power and
supplies only enough to
match the music level.
This high efficiency
PowerStorage circuit
can achieve 20W
output even with the
small quantity of power
supplied via USB.

Bass reflex speaker
Ordinary Bass Reflex Speakers
Many small speakers use a bass reflex
design with a port (opening) on the
front. However, the port is small, limiting
the bass. Lengthening the port increases
the bass, but also causes problems such
as bass lag and wind sound.

SR-Bass speaker
SR-Bass (Swing Radiator) Speaker
Yamaha’s SR-Bass (Swing Radiator Bass™) speaker
uses a Swing Radiator speaker diaphragm for the
port. It moves by the vibration of the main
diaphragm and efficiently increases bass energy.
This produces larger sound pressure levels without
Swing Radiator port
