EARLY INTRODUCTION
The CES can be a particularly good event,
not just for seeing and hearing new products
but also for the opportunity to network and
reconnect with friends, colleagues and other
industry folks. It was during the 2006 CES
that I was introduced to Daniel Barnum of
Half-Note Audio. At the time, he was the
importer for a line of breathtakingly built
though very expensive loudspeakers from a
UK-based company called Audio Acoustics.
After much discussion, Daniel arranged for
me to receive a pair of the company’s $96K
Sapphire Ti-C SE loudspeakers for review.
Quite frankly, given the price of this
speaker, I looked forward to assessing its
design and performance. Both speakers
arrived safely housed in shipping
containers. After hauling them around to the
back of my home, where we could easily place
the speakers into my listening area, I then
assisted (OK, I mainly watched) as Barnum
carefully removed each speaker from their
containers. I appreciated having someone who
could to do the heavy lifting as well as
handle these speakers so carefully and
meticulously.
Each speaker comes permanently fitted with
spiked cones. While this is a nice feature,
it definitely added to the challenge of
moving them around and placing them in my
preferred listening position. Fortunately,
Barnum was quite familiar with how to best
maneuver them and got them positioned so we
could check them out and make sure they were
operating properly.
Upon my initial visual inspection, I was
very impressed and could tell these Audio
Acoustic Sapphire loudspeakers were solidly
built and finished. I was anxious to start
doing some listening. But first, Daniel
rather carefully and methodically took a
series of measurements from both the side
and rear walls to determine where he felt
might be optimal placement for these
speakers. In the end, the speakers were
placed at nearly the same spot that my
reference ESP Concert Grand SI loudspeakers
were.
Along with the speakers, Daniel also brought
Audio Acoustics’ top-of-the-line cables: the
WOW Resonance interconnects and speaker
cables, as well as several AC cords.
Additionally, there were special Audio
Acoustics discs called Nano Pucks used for
isolation and energy transfer for the
speakers. In order to assess the overall
effectiveness of these products, we
systematically placed them in my system one
at a time.
DESIGN
APPROACH – TECHNICAL AND VISUAL
Speaking with the designer Shabir Bhatti, I
quickly sensed his deep and serious passion
for immaculate speaker design as well as how
best to execute his theories for reaching
the highest levels of sonic purity. But just
as impressive was the attention to detail in
the speakers’ flawless aesthetics. The pair
I received came in the superb finish called
Titanium Metallic. Additionally, their
overall fit and feel, and very good looks,
including the angular lines of the speaker,
along with its slender profile, help give
the speaker a sleek elegant look. Being able
to easily integrate these looks into just
about any room configuration or decor is an
absolute plus and something the designer
obviously took into consideration.
According to Bhatti, the design – in respect
to his loudspeakers - is the result of
intense research and development to produce
a loudspeaker with no compromise. His design
approach specifically covers important areas
such as: enclosure, port, diffraction, drive
units, resonance control, cables, crossover
network and floor coupling. Specifically,
his design approach addresses removal of
multiple resonances that are typically
overlooked in various commercial designs
with the ultimate goal being to offer a
speaker with dramatically superior dynamic
range along with as high a level of
naturalness possible.
In particular, the Audio Acoustic Sapphire’s
enclosure is a six-layer laminated cabinet
incorporating three types of membrane, each
with its own specific characteristics, along
with stainless steel panels. The specific
purpose of this design is to control
vibrations - not simply add mass and
stiffness. This design also effectively
addresses the elimination of cabinet
coloration and enclosure distortion.
Additionally, these speakers incorporate a
port on the lower front of the speaker.
Fortunately, I was unable to detect any ill
effects so often noted with speakers having
a port design. This port was uniquely
designed for optimum airflow control and for
eliminating various aspects of internal air
compliance factors.
Careful attention has also been given to
produce a structure addressing cabinet edge
diffraction along with internal shaping to
eliminate internal standing waves,
specifically in conjunction with the third
membrane. Also, a time-aligned driver layout
enhances the point source approach of the
speaker. Audio Acoustics seeks out the very
finest and most technically advanced drive
units with the goal, according to the
designer, to employ drivers that have
diaphragm motion that is strictly pistonic
and free from resonance across a wider
bandwidth than the frequency range the drive
unit is required to operate.
Also, the unique sapphire diaphragms used
have only a fraction of the mass of
conventional drivers, yet are purported to
boast superb levels of stiffness compliments
of complex magnet structures. Also according
to the designer, Audio Acoustics uses
drivers with titanium voice coils resulting
in distortion elimination, high definition
and resolution with superb transient power
and extended, organic bass. As stated by the
designer, one of his primary goals is to
produce a “quiet” speaker where only the
sounds from the driver diaphragms are heard
and not accompanied by extraneous sounds
caused by uncontrolled resonances or
vibrations.
Perusing the Audio Acoustic loudspeaker
website, I found loads of information on
Bhatti himself; his design theories and
concepts but perhaps more importantly his
reasons as to why he decided to build the
Audio Acoustics Sapphire loudspeaker in the
first place [here].
Shucks, one may never justify how a
loudspeaker can claim a $96k retail price
ticket but after reading and digesting all
the data behind such a terrific product, it
did help me in understanding Bhatti’s design
and his company Audio Acoustic, a lot
better.
In the area of cables, the Wow Resonance
cables are an extension of Bhatti’s research
and attempt to create system synergy for his
loudspeakers. The network crossovers
contain, according to Bhatti, the finest
component parts available with near
zero-tolerance silver capacitors and
air-core inductors. Additionally, says
Bhatti “they incorporate top quality silver
with extensive use of resonance-controlling
membranes. They are then torqued into place
to form a harmonious compound sealed
structure.”
Lastly, the spikes employed are a 3-point,
floor-coupling system designed to address
superior energy isolation. The spikes are
machined from steel, receive repeated
hardening and are nickel-plated (and
polished). According to Bhatti, this process
produces a hardness close to titanium
resulting in a durable point capable of
supporting the heavy speakers. These are
then coupled to the Nano Pucks which are
designed for energy transfer and isolation
control.
