Life Lessons
and the Ethics of Favoritism
When I was sixteen I worked as a cook in a small
restaurant my father owned. With dad as my boss, you
might think I had an unfair advantage over the other
employees. Quite the contrary. My father was much
tougher on me than on my co-workers. Years later I
would come to understand his logic. Because of our
relationship, he expected more from me. He also knew
if he treated me favorably, it would it adversely
affect the morale of the other employees or even
turn them against me.
That lesson stuck with me and is particularly
applicable in audio reviews. While I've read the
countless audio-forum posts lambasting reviewers for
their alleged bias toward manufacturers that
advertise in the rag or provide the biggest
accommodation discount, in my experience most of the
reviewers I know are ethical and as objective as
possible. While I'm human and subject to all the
flaws associated therewith, when it comes to
reviewing products from manufacturers I know,
respect or admire, I do as my father did with me and
try to avoid even the appearance of impropriety.
With audio reviews as in life, I also apply the old
adage: Of those to whom much is given, much is
expected. The more I know and respect a designer
or manufacturer whose product is in for review, the
higher my expectations and, therefore, the higher
the potential for disappointment.
I
know and like Andy Payor, the owner of Rockport
Technologies, and I have the utmost respect for his
design capabilities. For those who have been in this
hobby a while, you may initially and instinctively
associate the name Rockport with state of the art
turntables. Today, Rockport's line of loudspeakers
is almost equally distinctive. So, when Andy called
me asking if I'd like to review his Aquila
loudspeakers, I jumped at the opportunity. My
initial excitement, however, was counter-balanced by
my huge expectations. Of those to whom much is
given, much is expected. God blessed Mr. Payor
with a boatload of talent so I had a boatload of
expectations. Rather than a preconceived favorable
bias, my increased expectations more likely put the
Aquila at an almost unfair disadvantage.
Arrival and
Set-Up
When the Aquilas arrived, I was surprised at the
sheer mass of the wooden crates standing in my
driveway. Thank God for the friendly freight-truck
driver who helped me get 1,100 pounds of
refrigerator-sized crates into my foyer. While
removing them is a two-person job, once safely
removed, one person can, with the aid of Teflon
furniture movers, maneuver these 300 pound beauties
into place - albeit with a bit of effort.
My listening room is 14' x 18' x 8' and heavily
treated with a combination of ASC Super Tube Traps,
Echo Busters and Michael Green acoustic products. I
was either lucky, smart (unlikely) or a bit of both
but it didn't take too much trial and error to get
the Aquilas dialed in to where the image, soundstage
and frequency response all clicked. That final
position ended up with the Aquilas sitting 60" from
the rear wall (measured to the front baffle), 33"
from the side wall and 96" apart (measured from the
center of the tweeter), with a moderate degree of
toe-in (the point of convergence being slightly
behind my listening chair).
Born of
Technology, Fueled by Passion.
I don't claim to be Andy Payor's best friend or know
everything about him. What I do know is that Andy is
a gifted and highly talented engineer whose designs
are grounded in science but not applied in a vacuum.
I also know Andy as a music lover. To me, this
aspect of his personality also contributes to the
success of his technical designs. For anyone who has
seen (or heard) the technical implementation of a
Rockport Sirius III Turntable, you have witnessed
Andy Payor's fanatical attention to detail and his
dedication to build quality. Ditto the Rockport
loudspeakers.
The Rockport Aquila, at $45,500.00, is the third
from the top in the Rockport hierarchy of
loudspeakers (behind the Altair and the top of the
line Arrakis). The Aquila is a floor-standing
three-way design incorporating a 13" side-firing
woofer, a 6" midrange driver and 1" modified ring
radiator tweeter. The woofer and midrange drivers
are custom-built for Rockport Technologies using
Rockport's proprietary, variable section thickness,
carbon-fiber sandwich composite cones. These custom
cones (designed and tooled by Rockport) are then
coupled to custom designed motor systems built by
Audiotechnology of Denmark. Rockport's latest
generation of drive units combines ultra stiff,
light, well damped composite cones with motor
systems renowned for their exceptional linearity,
headroom (both mechanically and thermally) and low
noise floor (the ability to remain linear and
continue to resolve at very low volume). According to Payor, this construction
allows the woofer and midrange drivers to maintain
virtually perfect pistonic behavior well beyond
their intended operating ranges. This reportedly
translates into highly textured, ultra high
resolution sound with a very natural (and wide)
dynamic continuum that extends from the very first
octave throughout the entire frequency range. My
listening experiences confirmed Payor's claims.
The Scanspeak D30 tweeter used in the Aquila
features a modified ring radiator motor system
coupled to a soft dome. Payor asserts that the
tweeter's off-axis response is superior to other
tweeters in its range, helping the Aquila to provide
excellent imaging due to the loudspeaker's
linearity. This tweeter is also stated to have a
very low resonant frequency and robust construction
that allows it to be crossed over quite low while
retaining enormous power handling and dynamic range.
Frequency response is listed at 25Hz - 20k KHz with
nominal 4 ohm impedance and a sensitivity of 89dB (SPL/2.83v).
Frequency division for the Aquila is handled by a
24dB/octave acoustic slope network featuring point
to point wiring, custom inductors and custom
film/foil capacitors designed by Rockport and built
to its specifications. Each individual loudspeaker's
crossover is tested and fine-tuned to optimize
frequency response and proper phase summation before
being fully encapsulated in Rockport's proprietary,
high hysteresis loss epoxy (stated to provide
mechanical stability while minimizing both
microphonic and magnetostrictive effects). Internal
wiring is provided by Transparent Audio.
The Aquila's cabinet is a constrained-mode damped,
multi-layer MDF enclosure with variable section
thickness, (up to 3" for the side walls and 5" for
the front baffle) featuring ten internal braces
purported to give the enclosure incredible stiffness
and minimum resonant signature. While the Aquila is
not a monocoque design constructed from the same
acoustically inert resin material found in the
Altair or Arrakis, if you were to touch, lift or rap
your knuckles on the Aquila's cabinet, you certainly
would never know it (rapping the cabinet feels like
hitting a bowling ball). Unlike the former Antares
(the speaker the Aquila basically replaces in the
Rockport line), the Aquila has a slimmer front
profile due to the side mounting of its 13" bass
driver. Finished in flawless and beautiful piano
gloss black, the Aquila stands 47" high and
approximately 32" deep and, at it widest point (the
base), is 18" wide (although the enclosure is only
about 13" wide). Four (4) substantial 2” diameter
spikes are threaded into each base. When viewed from
my listening seat, the Aquila appears sleek and
unobtrusive. Only when you walk up and view it from
the side, do you realize how deep the cabinet is and
appreciate its required volume. As I've heard Andy
Payor state on more than one occasion, There's no
replacement for displacement.
Finally, I don't know what it says about the sanity
or the social life of those of us who can be smitten
with the visual pulchritude of a piece of audio
equipment, but I find the raked-back, sleek, yet
powerful appearance of the Aquila visually stunning.
