Как вам такие штуки - Shakti Hollographs? Можно такие краснодеревщикам заказать (по фото), думаю сделают дешевле, чем 1300$ ритейла
Пишут очень красиво (сорри, лень переводить):
"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."
What makes the Hallographs unique?
"It's the intentional contouring of the reflection signal and the high level of diffusion from such a small surface area. As I mentioned earlier, the Hallograph is almost like a secondary speaker that to some degree decouples the primary speaker from the room. Instead of softening the room sounds, which requires extensive materials and treatment, we tried to produce a musically complimentary device that dominates what the listener hears as the earliest reflections.
"The direct energy from the speakers already contains the ambient cues the microphones picked up at the recording site but the room modifies the image, writing over its own signature and ambient cues. So, while we can't eliminate the room, we can reduce the perception of it to some degree by introducing a new boundary that is designed as a diffuser, one that has superior geometry to the room's flat surfaces.
"Typical reflector/diffusers use a single type of wood and/or absorbent material mounted against each other. Let's call these the paddle type. The diffusion in these types is generated from the asymmetrical depth of the pieces in relation to each other. Hallographs use a spaced, undulated and rounded-over fork type geometry to achieve the asymmetry essential to produce diffusion. In addition, there are four different types of wood used in our product. Our open fork design has double diffusion because the return wave off the wall is sent through the diffusers a second time unlike with the paddle type. If you think of the secondary sound waves in a room as water moving chaotically in all directions, this fork type diffuser has a much more powerful smoothing effect per square inch than the paddle type diffusers. That makes it akin to a powerful propeller that the water, or in this case the sound waves, go through to smooth out their peaks. Our diffuser has 60 undulations per channel and rounded-over edges that multiply the surface diffusion taking place. Unlike paddle type diffusers, which require many more panels, one pair of Hallographs can have a dramatic effect."
"Our stand, which is 4 feet in length, is also asymmetrical and does produce some audible improvement in bass clarity. Again, the goal is to push the room's enormously distorting effects further into the background with a far more neutral ambient soundfield. The reflector material in the Hallograph consists of several types of wood that all have different resonant signatures. All the wood lengths are staggered on the three reflectors. Each reflector has a flat surface that gently curves into a round-over section. These interlaced but geometrically different surfaces have a striking effect. The Hallograph's own direct return energy (from the flat portion of the reflector) and its ambient signals (from the curved reflector area) impact the sonic envelope one hears. This ratio of direct to ambient surface tuning, just as is the case in a concert hall, restores a more natural hall acoustic. So, the inherent differences from recording to recording are no longer stamped with the listener's room signature. Instead, the various original venues are heard far more realistically. Behind each reflector is a chamber that modifies the frequency response, amplitude and most importantly, the time signature of the reflector. This creates a complimentary interface between the speaker and the room."
Speaking of which, what about the choice of woods?
"The black African wood potion of the Shakti reflector has a tight pore structure. It's more like metal in its speed of return of sound as compared to a room's walls. Imagine you were standing on some railroad tracks four miles from a train coming and I was only two miles away but not on the tracks. You, though twice as far away, would hear the train before I did because of the faster transfer of sound through the metal rails."
Есть восторженные review на 6moons и даже на аудиогоне
да кстати если краснодеревщикам заказ не оформили то не забудьте заказать shun mook
