"The
P10 is glorious
music at its
best..."
--Lewis Lanese
"Oh
no, not another
speaker
system"! Well
believe me, this
is not just
another speaker
system! In my
humble view, the
Piega P10 takes
its place among
the most rewarding
speakers it’s
been my pleasure
to hear. No, it’s
not one of those
systems that hits
you over the head
and says
"Listen to
me, I’m real
hi-fi". The
P10 is glorious
music at its best,
the kind of
speaker that makes
you forget about
audio, video, demo
records, high-end,
home-theater,
etc., and just
sit back and
enjoy!
It
was unbearably hot
in Milan! Anita
and I had gone to
Italy in September
hoping to escape
the hot Italian
summer but the hot
weather hung on.
So, it was with a
sense of relief
that I was on the
Cisalpino, one of
Italy’s modern
fast trains,
headed for
Switzerland
knowing it would
be cooler there.
The sheer beauty
of the Swiss Alps
with the small
picturesque
villages nestled
in among the
mountains made the
3 ¾ hour trip
pass very quickly.
The moderate
temperature was
invigorating.
When
he heard I was
going to be in
Milan, Carlo
Struchtrup, Piega’s
very affable,
friendly Export
Manager, invited
me to the factory
in Horgen,
Switzerland. I was
already in the
midst of reviewing
the Piega P10
Reference speaker
system. Some of
you may remember
that I reviewed
the P5 for STEREO
TIMES six
months ago and
said "...that
I could live quite
happily with the
Piega P5s; they
are that
good!" Thus
it was with great
anticipation that
I looked forward
to the P10. I
was not to be
disappointed!
Piega’s
headquarters,
located on Lake
Zurich, fifteen
minutes from the
city, is a model
production
facility presently
being enlarged to
twice its size.
Although
relatively unknown
in the United
States, Piega SA,
founded in 1986 by
Leo Greiner and
Kurt Scheuch
(engineers in the
field of
electromagnetics),
is very successful
in Europe
supplying a large
number of popular
high-end and home
theater systems.
Its products have
been highly
acclaimed in the
European audio
press. On the
basis of my
experience with
the P5 and P10, I
enthusiastically
recommend that you
take the
opportunity to
audition them if
one of the few (at
present) dealers
is convenient to
you.
Technical
Aspects
Yes,
the P10 is big! It
is a ported,
three-way, floor
standing
loudspeaker nearly
four feet tall,
narrow but deep
(almost 16")
with a
considerable
internal volume of
120 liters for the
two 8.5"
woofers. But
because it’s
narrow and deep,
it doesn’t
appear that large.
The special,
proprietary Vifa
woofers can and do
produce
substantial,
weighty bass when
the source demands
it. There are two
front firing
ribbons: a
midrange ribbon
about four inches
square; and a
tweeter about 2.5
x 1.5 inches.
There is a second
rear, firing
tweeter that may
be covered if your
room is already
very lively. All
of the drivers
have been very
carefully selected
and matched to
eliminate the
slighted
variations. The
crossover is
fourth order (24
dB per octave)
with the crossover
points at 500 Hz
between the
woofers and ribbon
midrange, 3.5k Hz
between the
midrange and
tweeter and 7k Hz
for the rear
firing ribbon
tweeter. As I
noted in my P5
review:
The
connector plate
on the rear of
the cabinet
provides for
bi-wiring and
sports several
switches mostly
to adjust for
differences in
room acoustics.
The "Low
Level"
switch allows
you to toggle
between
"normal"
and
"extended"
response;
"extended"
provides for
flat, low
frequency
response,
"normal"
cuts frequencies
below 40 Hz
where low
frequency
distortion such
as turntable
rumble might be
a problem. The
"High
Level"
switch has three
positions
"N, -,
+";
"N" is
for flat
response,
"-"
represents a 2
dB cut from 5k
Hz to 18k Hz,
"+"
represents a 2
dB increase from
5k Hz to 18k Hz.
All my listening
was done with
the switches set
at
"extended"
and
"N".
During
my visit to Piega’s
production
facilities I was
able to view the
procedure for
manufacturing
their unique and
proprietary
ribbons (pleated
to create rather
stiff membranes
that don’t
change impedances
with frequency –
similar to a
conventional cone
driver). As you
can see in the
photographs, with
both the midrange
and tweeter a jig
is used to press,
stretch and
assemble the
driver:
|

|
The
stretched and
pressed foil
is attached to
the form and
placed in the
magnetic
assembly (on
the right side
and above the
foil). The
finished
midrange is
now ready to
be installed
in the
cabinet.
|

|
Again,starting
above is the
raw foil that
has been cut
to size,
pressed and
the tweeter
assembled.

On the
far right is the
completed
tweeter.
"I
detected no
obvious cabinet
vibrations/colorations
in the many
hours of
listening."
The
cabinet panels are
double thick MDF,
nearly two inches!
Bituminous plates
cover all interior
surfaces of the
cabinet. The
tweeters are
sealed in the rear
while the midrange
ribbons have their
own separate
sealed
compartment. The
remaining internal
volume (devoted to
the woofers) is
constructed with a
matrix similar to
the B&W and
filled with
polyester wool. It
is no surprise
that the weight of
each speaker is
139 lbs. How
successful is this
elaborate design
and fabrication? I
detected no
obvious cabinet
vibrations/colorations
in the many hours
of listening!
In
the illustration
you can see part
of the matrix, the
crossovers and
some of the
bituminous plates.
Setting
Up The System
The
Piega provides for
bi-wiring or bi-amping;
I bi-wired them to
my VT 8000 MK
monoblocks. You
also have the
alternative of
strapping
(provided) the
speaker
connections and
using a single
speaker cable. It
is always a bit
painful going
through the
"break-in"
period for a new
piece of equipment
and it was no
exception with the
P10s. Now and
again I sneaked a
listen but it was
a good two to
three weeks before
I began to
seriously listen
to the Piegas.
Initially
I set up the
speakers in what
is usually typical
in my living room;
nine feet from the
rear wall, 52
inches from the
side walls and
toed in toward my
listening
position. When
serious listening
begins I then make
adjustments for
imaging, focus and
depth keeping in
mind the balanced
response of the
system. All of
this is dictated
by the dimensions
and liveliness of
the room which is
15’ wide by 25’
long, with a
cathedral ceiling;
at the apex it is
9’ high and 5’10"
at either end.
Fortunately Bill
Brassington
happened over when
I was working on
placement: when it
comes to ideally
positioning the
speakers Bill is the
guru. (Final
placement must
wait until the
speakers are
broken-in.) We
ended up moving
the speakers about
36 inches from the
side walls and
toeing them in
more acutely. With
the P5 I had to
augment the low
bass with a
subwoofer since it
was so far from
the rear wall.
That was not
necessary with the
P10.
Since
the Bidat D/A
converter has its
own wired, remote
gain control,
initially the CD
source was
connected directly
to the amplifiers.
But most of my
listening was
through the preamp
that provided more
realistic
dynamics.
Sound
Experiences
"...air,
openness and
detail I have
not quite
experienced with
any other
speaker."
Piega
has attempted to
make a serious and
significant
statement in the
creation of their
reference P10.
There is major
competition in the
$8,000 to $12,000
price class -
B&W, Dynaudio
and Von Schweikert
(his new speakers
will be shown at
CES 2000) to name
but three. True,
there are many
excellent speakers
from which to
choose. And true,
each is different
than the others;
different, and
sometimes unique,
in the design and
execution, and
different in the
way each behaves
synergistically in
a specific system
and certainly in
the way each
behaves in a
particular
acoustic
environment.
The
P10 is unique in
the proprietary
design and
application of its
ribbon drivers.
Piega have gone
all out to
hand-pick and
match each item
from among the
components that go
into the
manufacture of the
speaker (you could
probably say as
much for the
Dynaudio
Confidence 5, the
Von Schweikert VR6
as well as the
B&W 801 or
802). But have
they succeeded in
reaching their
objective? My
answer is a
resounding yes!
The
Piega’s were
nine feet from the
rear wall yet
there was no lack
of low bass. The
interior matrix
construction,
double-thickness
MDF, bituminous
panels on the
inner walls and
polyester wool
filler all
contribute to the
virtual
elimination of any
cabinet
coloration.
There
was a measure of
air, openness and
detail I have not
quite experienced
with any other
speaker – not a
fatiguing
"hi-fi"
kind of sound but
relaxed with
refinement and
control and
altogether true to
the music. I
attribute this to
the ribbon drivers
that operate from
500 Hz to far
beyond my hearing.
But I was never
aware of the
ribbons i.e. they
never highlighted
themselves, so
faultless and
natural were they.
Whether I was
playing CDs or
LPs, the Piegas
were consistent in
their
reproduction.
The
recording of "the
name is Makowicz",
Adam Makowicz
on piano, Phil
Woods on
saxophone, with
Marc Johnson, Phil
Goodwin and Gene
Estes (Sheffield
Lab 21) is a
"Direct-to-Disc"
LP release that is
surely
out-of-print (it
may be available
on CD). You might
feel it is unfair
to highlight an OP
disc but there are
some outstanding
examples of
superbly recorded
percussion, drums
and piano on this
jazz record. The
cymbals as
reproduced on the
Piegas have a live
quality that I
have never before
quite heard with
any other speaker.
Piano,
drums and
percussion on this
recording will
expose anything
less than superb
transients in a
system. The
extraordinary
response of the
midrange and
tweeter ribbons
together with the
speed of the two
Vifa 8 ½ inch
bass drivers were
more than up to
the demands of the
record. The
Sheffield record,
as well as several
others in my
collection, as my
listening notes
indicate,
demonstrate a
coherence,
neutrality and
lack of coloration
matched by very
few speakers in my
experience. Air
and openness,
transparent yet
sweet, a solidity
in the bass
together with
outstanding
dynamics are the
hallmarks of the
Piega P10.
There
was an effortless
quality in the
reproduction that
contributed to
hours of listening
without any sign
of fatigue. The
speakers were
always involving,
delivering impact
and invariably,
tonally correct.
Whether I was
listening to jazz,
classical, opera,
popular or rock,
the speakers
rendered what the
recording
required.
I
measured the
frequency response
with the Gold Line
Real Time Analyzer
setting the
microphone at my
listening position
and using pink
noise from a CD
test record. The
graphic results
displayed what in
fact my ears had
told me. The
response was
generally flat,
not varying more
than +/- 5dB. At
25 Hz , response
was down only –3dB.
Those, of course,
were the results
within the
acoustical
environment of my
living room.
Conclusion
Piega
is a Swiss speaker
manufacturer whose
products have
recently been
introduced into
the United States.
The most recent Audio
Directory
lists far more
speaker systems
than any other
single audio
category. The
high-end market,
particularly for
new speakers, is
very competitive
and certainly at a
time when
computers and
home-theater are
having such an
impact on audio.
However, the P10
is a serious entry
into the
loudspeaker
market. It is a
system that is
coherent,
balanced, tonally
accurate, detailed
and open, with
dynamic impact,
clean transients,
good imaging and
depth; a system
that is effortless
in its
reproduction of
music that will
reward you with
many hours of
listening without
fatigue. Perhaps
the most
impressive thing
about this speaker
is that you can
play it at ear
shattering levels without
the speakers
compressing the
sound or becoming
raucous or rift
with distortion!
It is simply
louder!
Alternatively, at
low levels they
maintain all of
their most
positive qualities
without losing
dynamics - a most
impressive aspect
of a top notch
system!
If
you are an
audiophile or
music lover who
has always loved
the special sound
of electrostatics,
ribbons and
similar speaker
systems but
despair at the
lack of dynamics,
low bass or
unacceptable union
with dynamic
woofers in hybrid
versions, then
take heart, the
P10 has solved the
problem! No, it is
not a ribbon
dipole but these
unique ribbon
drivers have the
best of what is so
coveted with this
technology and
they are married
to fast
proprietary
woofers with
excellent lows,
midbass and
dynamics. On the
other hand, dear
reader, if you are
simply turned on
by full range
speakers that have
all the qualities
of an excellent
speaker system,
whatever the
design, and
without the
necessity for
subwoofers and the
like, then I urge
you to take the
opportunity of
hearing the Piega
P10. I have yet to
hear a speaker in
this price class
that betters the
P10. The
Piega P10 is now
my reference
speaker and I
expect it to be
for a long time to
come!
To
answer the
question posed at
the beginning of
this review, yes,
this is the
best of both
worlds!
P.S.
After the
completion of this
review, I added
the Sony SCD-1,
Super Audio CD
player to my
equipment. The
Piega took full
advantage of this
wide band 20 Hz
– 50K Hz (100K
Hz in the Custom
setting) system,
demonstrating the
immense
superiority of DSD
over conventional
CDs. (See Clement
Perry’s full review
and my initial
impressions
of the SCD-1)
If
you expect to be
at CES 2000 in
January you will
find Piega
exhibiting there.
Sometime later in
the year 2000,
Piega will release
a
"cost-no-object"
speaker system.
