Introduction to Sonawall (SRT) Sound Reflection Technology

Utilizing the principles explored by Allison Snell and Carlsson SonaWall speakers furthermore combine the modularity of satellite speakers with integration on the wall. These tiny sPod satellites were created to integrate sonically with the back wall. By using the rear wall as a reflecting surface the listening experience is enhanced greatly and the listening position is extended in a natural way. The body of the midrange is also improved by this coupling. This allows the tiny satellites by enhancing their lower end to integrate with a selection of subwoofers.
SonaWall offers a selection of powered subwoofers available with built in power for the satellites. A variety of interfaces for various inputs and a remote control are combined in the system. The satellites mount to the wall with wide separation and a broad continuous image is provided. This placement and the unique angling of the “sPod” satellites virtually erase the wall behind the speakers by using that wall for sound support. Delayed wall reflections that would normally create midrange comb filtering are eliminated. Instead the sound is coupled immediately to the wall and smoothly enhances the forward radiated portion with that portion that would normally escape and be returned much later to interfere. Reflected sound enhances the perceived quality of the program material. The very highest frequencies are delivered directly from the sPod driver and when auxiliary tweeters are optionally incorporated in the sPod (SpodPlus) also into the ambient to raise the total radiated power. These complex enhancements raise the art of sound reproduction to new higher levels. The Close Coupling Process The SonaStudio 2.1 and SonaPlus 2.1 uses a coupled boundary concept to transform the listening wall into a virtual wall of sound. This boundary concept was originally explored in microphone design. The sPod is operating like such a microphone in reverse. The sound waves in the room are coupled to and appear to be mirrored from the wall. The large expanse of wall contrasted with the tiny size of the sPod enables this performance. Expensive high energy magnet technology also enables this small sPod size to be achieved.
Setup For maximum coverage use the largest expanse of wall available. Measure the typical listening distance from this wall and locate the center position. Each Pod will typically be positioned about seven feet high and twice as far apart as the distance from the listening position to the mounting wall. If this is impractical reduce these typical distances to fit the architecture. A more intimate listening system can also be reduced to the point of becoming a computer speaker setup. Keeping similar proportions is recommended. Alternately having the sPods asymmetrically mounted to suit an offset position among others may all be tested to accommodate virtually any room or listening arrangement. Even though the setup is altered substantially the advantages of the SonaStudio 2.1 may still be enjoyed. The wall is the essential element.
