breakthrough technology is the result of over 10 years of
research that studied the effects of the speaker/room interface. We learned how to reduce
the audibility of the chaotic reflections from the walls of the listening room so they
wont overpower and interfere with the direct sound from the speakers. The Hallograph
contours the frequency, amplitude and time coefficients of the first reflections you hear,
which produces a stunning increase in realism.
Soundfield Optimizer consists of two arrays that are easily
placed behind each speaker near the corners of the backwall. Each array is engineered with
proprietary technology (patent pending) and made with exotic hardwoods, consisting of
staggered activated panels that are mounted on an elegant base that beautifully blends
into any style room environment.

RENOWNED MASTERING ENGINEER
STEVE HOFFMAN ENDORSING THE HALLOGRAPH AT CES 2003
The Hallograph is an amazingly
worthwhile and effective device. I've had it in my system for a couple of weeks of heavy
listening and am hooked (no break-in required). In my system, the soundstage became
deeper and wider, images gained in intensity and size, while high frequency extremes lost
some stridence. Information retrieval (or should I say "unmasking") goes up a
notch, as details that were previously masked by room reactions reclaim their prominence
in the mix. Vocals gain in intelligibility and clarity. Importantly, it appears to be very
neutral, or evenhanded, if you will, in its impact across the spectrum -- nothing pushed
at you or rolled off to create an artificial sense of impact. Quite the opposite, in fact
-- the whole musical presentation seems to be naturally set in its recording venue to a
The cumulative impact of all this
is to peel off a previously unobserved thin layer of glaze from the music. It just has a
fresher feel, closer to lifelike. If you've ever ridden a bicycle in a rural setting right
after the rain, the air has a glorious, exhilarating dimension, scrubbed clean.
Subjectively for me, that's the best way to sum up what the Hallograph does.
I just received your Hollograph
yesterday and got it set up. Wow ! I'm very impressed! The changes that can be made are
surprising. When I read in the directions that you could hear a difference when only
tuning the array 1/8" I thought I probably wouldn't be able to hear it . I then tried
several changes and found myself laughing with amazement at the possibilities for
customizing the sound. Very cool !! I don't see how it can work, but it does, and it is
very very cool ! How did you get the idea to try and develop something like this ? It
seems to be such a different approach than anything else on the market.
Congrats, and I hope it all works
out for you. If you have any other secrets let me know. I'm sure I would be interested !
My initial reaction upon hearing
the Shakti Hallograph Sound Field Optimizer in my home has been nothing short of amazement
in the enhancement of my system¹s sound. Not only has the soundstage width and depth been
enhanced, but the resolution within the soundstage is spectacular. The bass exhibits
greater control with midrange and highs that are now more articulate and less strident.
Most importantly, I am now drawn
into the music to a degree that I have never experienced before.

Thanks again for the great follow-up on my Hallograph Soundfield Optimizer (say that fast
I received the Hallograph the first
week of January, and found it very easy to set up. My wife's visual reaction was
"it's not as bad as I thought it was going to be" and "though weird, works
well with our contemporary décor." The wood is well finished and the overall
effect is more akin to a fun sculpture.
But this is really about sound
reproduction, not aesthetics. The Hallograph does for my audio system what laser
vision does for my sight. Smearing of tones, edginess of timbre, and wooly bass have now
vanished to be replaced by a clarity of pitch and timbre, an improvement in micro and
macro attack, bloom and decay, and a very natural, you are there sense to all types of
music; chamber, symphonic, jazz, male or female vocals, massed chorus, and opera. I have
been tweaking my system for years, and have made some very good improvements this past
year. The Hallograph stands with the best of these improvements (components, cables, and
the ubiquitous Shakti stones) and for the most part at a much smaller investment. They
truly are adjustable with audible changes, and I have had some fun "tweaking the
tweak." In my room with my speakers, setting the Hallograph's "vanes" dead
center on left and right is for my ears the best overall presentation and balance.
It is very hard to turn the system off at night. I find so much new enjoyment
with my most familiar recordings (on CD, HDCD, SACD and vinyl).
The Hallograph Soundfield Optimizer
is a mouth-full to say, looks strange in pictures, is hard to comprehend at first sight
how or why is should even work, and does everything as advertised. Thanks again for making
this hobby so much fun and for producing an audio product that is so effective.
Quotes from reviewers
"The spectacular sense of spaciousness didn't really surprise me, as
I had heard that effect at my very first encounter with the Hallographs. But that brief
CES audition did not prepare me for the myriad other improvements offered by the
Hallographs. Bass gets quicker and tighter, with better pitch definition. Vocal and
instrumental images typically have more dimensionality and lateral stability. Previously
unnoticed low-level detail emerges, and the entire presentation takes on a more relaxed
and naturally musical quality that is hard to describe, but easy to love (in my case,
often deep into the night)." Wayne Donnelly, Ultimate Audio now at www.enjoythemusic.com
Shakti Hallographs have become permanent parts of my system. At $1000 a pair, they are not
cheap, but they can transform a system, even one in a highly treated room. A very strong
selling point is that they look like pieces of art and not room treatments, so will be
likely to have a much higher "roommate" acceptance factor. The improvements they
make are essential to enjoying music to the fullest." Clay

"The Best New Room Treatment at
the show was by Ben Piazza of Shakti. This was demonstrated in the
E.A.R. room. The Hallograph Soundfield Optimizer is a tall floor-standing wooden
device designed to work in the room corners behind the speakers. On top of a wooden post
are three vertical wavy wooden segments, made out of two different kinds of wood, each
containing a resonant chamber. They are difficult to describe in words, but they did
work. With the devices in place, the soundstage filled out and the midrange and
treble sounded more natural. With the devices removed, there was reduced ambience and
naturalness to the sound."
"... Ben leads me up
to his room. Yes! Lest one has not caught on, CES is all about male-on-male seduction. And
we of the press, star. Babes for hire in Toyland! Anyway, Ben is showing a novel room
treatment called the Hallograph. Unlike his more discreet Shakti Stones, which have become
the favorite whipping boy of stiffs in audio academic society, here is something out in
the open. Hallographs, probably TM although I dont see a sign, are three wavy
upright pieces of exotic wood that perch in the front corners of a room on tall thin
poles. Scarcely a nuisance, visually. Kind of attractive, actually.
I mean, they also sound
good! I mean, no sound comes from them, and yet... What I mean is... These Hallographs
assist the hi-fl by helping to recreate a real sense of sonic space. I do not say that
lightly. Removing them proves the point. In two systems, one major, one minor, both in
mediocre rooms, Hallographs make the difference between great sound and good. And
were talking sound by E.A.R., thats Tim de Paravinci, which would otherwise be
quite acceptable, tonally, before adding the Hallographs. I predict that these light
wooden sculptures, which may even elicit ahs of wonder from artists and ladies, shall
become in one form or another a standard feature of good rooms.
In the two locations one
can hear them, Hallographs impart a sense of presence to the music unlike any other room
trick I have ever heard. Astonishing. Congratulations, Ben. Although who knows how they
may work in better environments? At any rate, for under $1000, they seem well worth
