These are two great original Shakti Hallographs that perform wonderfully. They truly reduce room distortions and allow you to hear more of the music. They have one small cosmetic blemish shown in photos. They are ready to safely and securely ship. “The Hallograph Soundfield Optimizer 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 Hallograph Soundfield Optimizer consists of two arrays that are easily placed behind each speaker near the corners of the back wall. 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.”

These devices definitely have an impact on a listening room, and during the time theyve been in the corners behind my speakers, my system has never sounded better. Theyre in very good cosmetic condition, there are a couple of minor knocks from where they were moved around but I doubt this has impacted on their function. Theyre tall - 180cm, made from hardwood/plywood and in the UK they retail for 2,700. They can be angled to focus the soundfield. Experimentation is highly recommended. Shipping them is going to be really awkward, the bases are 125cm tall so for safety theyll need a pretty massive box. The tops do come off though and if thats all you want I can reduce the shipping cost. I dont normally do this, but because theyre pretty esoteric, they were expensive and have a fairly limited appeal, Ive set a reserve of 300. Collection in person is welcome. Until they sell, theyll be back in the corners of my listening room. If there’s no Buy It Now price displayed, there’s no Buy It Now price Unless stated, I ship overseas.
