Articles about Helmholtz:

Synergistic Research has introduced a collection of devices, the Acoustic A.R.T. System, that promise to make room acoustic treatement gorgeous.
The A.R.T. system is a small 5 piece room treatment kit consisting of metal spheres, bowls, and wooden block supports, designed to be placed on the rear wall between the speakers and on the side walls.
According to the company, the system is inspired by Tibetan prayer bowls and is based on the principles of Helmholtz resonators.
The Acoustic A.R.T. System Components
- The main piece of the system is called the Vibratron. The Vibratron is placed on the rear wall just above the tweeters of the speakers, and consists of a two part metal sphere with a metal ring placed between the halves, and a vertical stack of magnets placed above the sphere.
- The next piece is the Bass Station, which is a spiked wood platform supporting a metal bowl, designed to be placed on the floor below the Vibratron.
- Finally, the Magnetron and Gravatron satellite bowls are placed on the first order reflection points on the side walls, and on the wall behind the listening position.
These are completely different than any acoustic treatment system I’ve ever seen, and leave me skeptical. Let me know what you think of them in the comments.
