There
are
many
terrible
things
in
this
world,
and
I
think
we
can
all
agree
that
running
speaker
cables
is
one
of
the
worst.
That’s
one
of
the
reasons
why
the
best
soundbars
now
have
wireless
subwoofers
and
sometimes
wireless
surround
speakers
too,
but
many
of
those
options
are
manufacturer-specific
and
some
wireless
connections
are
laggy
or
lossy.
US
firm
Fasetto
thinks
it
has
a
better
option:
Dolby
Atmos
via
your
home’s
power
lines.
Its
Audio
Cu
system
delivers
audio
without
lengthy
cabling,
and
it’s
just
been
certified
for
Dolby
Atmos.
Audio
Cu
works
in
much
the
same
way
as
powerline
networking
devices
do:
it
sends
signals
over
the
in-wall
wiring
in
your
home.
Audio
signals
are
sent
from
a
transmitter
attached
to
your
TV
or
AV
receiver,
decoded
by
boxes
that
receive
the
signals,
and
then
sent
to
your
speakers
as
normal.
The
system
supports
surround
sound
setups
up
to
7.1.2
with
Dolby
Atmos
and
should
work
with
any
speakers
with
the
familiar
black
and
red
wiring
terminals.
That’s
the
good
news.
Now
for
the
potentially
not-so-good.
How
much
does
wireless
surround
sound
cost?
We
don’t
know
the
price
yet,
but
it
isn’t
likely
to
be
cheap.
We
know
that
you’ll
need
an
Audio
Cu
receiver
for
each
speaker
as
well
as
the
main
Audio
Cu
transmitter
you’ll
attach
to
one
of
the
best
TVs
or
an
audio
source;
each
receiver
will
need
to
be
its
own
amplifier
as
well
as
a
receiver,
and
of
course
that
ups
the
cost
somewhat.
As
the
technology
is
largely
the
same
as
powerline
networking,
a
look
at
the
best
powerline
adapters
gives
some
indication
of
what
the
prices
will
be
at
a
minimum.
Is
it
worth
it?
According
to
the
firm,
latency
is
down
to
less
than
20
milliseconds,
there’s
virtually
no
packet
loss,
and
the
signals
are
not
affected
by
interference,
which
can
be
an
issue
with
over-the-air
wireless
connections.
A
single
transmitter
can
handle
up
to
10
channels
of
audio,
and
if
you
have
a
mansion
you
can
run
up
to
six
transmitters
in
separate
setups
in
the
same
home,
with
a
max
of
32
audio
channels
in
total.
You
don’t
need
an
AV
receiver
(though
if
you
have
one
of
the
best
4K
projectors,
you
may
well
be
using
one
anyway),
and
all
the
EQ
and
configuration
is
done
in
the
iOS
or
Android
app.
You’ll
also
be
able
to
control
the
volume
via
your
TV
or
projector.
According
to
Fasetto,
“The
future
of
home
audio
connectivity
has
arrived
with
AUDIO
Cu”
and
the
firm
is
“the
only
company
that
has
overcome
all
the
obstacles
of
moving
data
cleanly
over
power
lines
in
all
environments”.
If
the
system
is
as
good
as
it
sounds,
it
could
be
an
interesting
option
for
people
who
want
a
home
theater
setup
without
installing
cables
or
running
them
across
the
floor.
