"WOW! The improvement was shocking! Everyone should hear them in their own home. We are offering a 30 day satisfaction guarantee or your money back. I implore you to hear them for yourself!" - Robert Bantz / President of Elusive Disc, Inc.

The Hallograph 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 won’t 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.

"...the Hallographs' "baskets" could be so angled that the sonic soundstage and its surrounding ambient field could be, and was, precisely tailored for maximum coherency and authenticity." - Harry Pearson, The Absolute Sound, September 2007 Issue 174, page 117

The Hallograph 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.

More realistic presentation of stage depth, width and height, along with a warmer musical tonality that doesn’t compromise clarity and detail.

• Allows latest advances in State-of-The-Art electronics and speaker designs to be heard to their full potential.
• Each array is adjustable so that the system can be optimized for different rooms and speaker systems.
• Activated panels generate a musically complimentary reflective energy that transforms your listening room by overshadowing typical room distortions which muddy the bass, overbrighten the presentation and blur the soundstage.
• The Ambient detail of the original recording site is now finally revealed in all its glory.
• Beta testers were stunned by the level of musical improvement they were able to achieve when the prototype Hallograph arrays were put into their systems.
• Only one set is required per system. Easy set up with floor stands. The Hallograph array offers the kind of performance increase that’s associated with a major upgrade in speakers and electronics.

"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 greater degree."

"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. Highly recommended." - David Sparrow

"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!" - Bob Vaughan

"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." - Steven Plaskin, System: Wilson 6 speakers, Levinson 32 preamp with Levinson 33H amps.

" Ben, Thanks again for the great follow-up on my Hallograph Soundfield Optimizer (say that fast three times). 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." - Jack Simmonds

Prodcut Reviews:
"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

""The Shakti Hallographs have become permanent parts of my system. ...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 Swartz Positive Feedback Online APRIL 2003

"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." - Dave Glackin

"... 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 don’t 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 we’re talking sound by E.A.R., that’s 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... they seem well worth trying. OK, want a better quote? Here you go. Hallographs provide a fundamental, as-yet inimitable solution to room problems. They extract, rather than synthesize. Hallographs help unravel the tangled web that music reproduction in real rooms weaves."

"How’s that? Oh, and this just in. Later I revisit to find famous mastering engineer Stan Ricker, along with Dave Glackin, sitting in the catbird seats. Moments into the “A” play (which I happen to know is an old Merc, albeit on CD) Stan remarks, “That must be a Bob Fine recording.” Of course he is correct. Moments into the “B”, with Hallographs up, Stan bursts out: “Still a Bob Fine.., but, much finer!”" - Clark Johnsen

"As I sit here writing this short review, I have to admit something to clear my conscience. When I called Sam to order the Shakti Hallographs, I felt extremely confident that I would return them. I had performed my due diligence but was still harboring these “snake oil” perceptions. I even took photos as I unpacked them to make sure I could get them back in the box correctly. I have a working man’s system and, albeit nice, it is not on par with most professional reviewer’s systems. I have proper room treatments and also have spent a lot of time fine tuning equipment set up and calibration. My system, to me, sounds great. As with any audiophile, my opinion of “great” changes with the wind some days. I know that certain conditions (electricity, static, wax in my ears, etc.) cause variables and I accept small doses of discontent without making drastic changes. So, with that said, I know my system and its tolerances fairly well."

"As I said before, I was skeptical about the Shaktis. I am always interested in the idea that some new product can transform what I already am happy with into something better. The problem is that when you really get your system tuned in, you can spend a lot of money on things that improve your sound in such small ways that you are really paying a lot for a diminished return. Audiophiles can write books on this subject. Audiophile wives can really write books on this subject, and remind you of it over and over again. So, you can imagine the reaction from my wife as she wanders into my listening room and sees these objects that look like a pair of Poseidon’s tridents standing there. You know that reaction when someone gives a look of disappointment and shakes their head slowly as to say, “you sad, crazy and pitiful soul”? I got that look, with a little hint of evil eye added in for impact. It took me about 20 minutes to set the Hallographs up in the recommended position, outside and behind the speakers in the corners of the room, and angle them towards my listening position properly. I adjusted the toe-in slightly on both until I felt that the music sounded properly spaced across the span of the room and then I really started listening. Album after album, I tested different types of music with a wide variety of frequency and dynamic characteristics. I can’t explain how the Hallographs work in a way that would please an engineer, but I can say that they truly work in a wonderful, lovely way. It wasn’t a “blow me down” kind of reaction but more of a realization that I could hear everything clearer, more pure and accurate. The soundstage width was a fairy dramatic difference. Instruments seem to be coming from places in the room they didn’t before. I have always heard people say that you reach your goal when you can remove the physical speaker from the music. Well, that’s what they did. Everything I played was just more engaging, warmer, better defined. Instruments sounded better and more separated. I was actually really surprised as I continued to listen. They really work, weird! I woke up the next day in fear that I had just had a good day the day before and that my bliss would disappear. It was the same reaction the next day and they still continued to surprise me as I sit down to listen after having been away from my system for a day or two."

"I have to say, I doubted them from the beginning. I am sure a lot of others are thinking the same thing I was. I can’t speak for anyone else and I am sure that certain rooms are more of a challenge, but they made a believer out of me. I continue to be amazed." - Chip R., Alabama, Elusive Disc Customer.
