Wilson Benesch & HiFi+ Issue 83: Innovation

Wilson Benesch - HiFi+

This week issue 83 of HiFi+ has gone on general sale. You can now catch the second advert in a four part series which Wilson Benesch are running. Again for those of you reading the magazine using the iPad, there is a little something extra.

Wilson Benesch prides itself on remaining at the very cutting edge of design and technology, be it in the materials we use or the 3D CAD/ CAM suites that form the very heart of our manufacturing suite. So for each of the adverts in this series Wilson Benesch will be preparing something a little extra for the iPad readers of HiFi+.

In this, the second advert in the series, iPad users will be able to watch the new Semisphere Tweeter ‘explode’ and rotate live in the ad through 360 degrees.

The Semisphere comes out of one of the longest developments in the companies history, dating back to the first drive unit ten years ago. It has grown slowly out of everything that we have learned from the best tweeters in the world, including the remarkable Piezo tweeter sourced from Murata, the Sphere.

The Semisphere takes its starting point from soft dome technologies, where damping guarantees that the sound will remain clean and notable, without sounding hard or tiresome after a short period of listening. In every way the character is both natural and convincing.

Transient response characteristics are absolutely outstanding, thanks to the advanced materials technologies and their extremely low mass, that is almost one third that of the previous tweeter that it supersedes.

The dome is driven by one of the most powerful rare earth motor systems in the world. Careful attention to air flow, sees venting at both the side of the coil and rear, allowing any unwanted energy to pass unhindered into the huge silencing chamber.

The high mass of the system which is bolted to the alloy baffle ensures that the first resonance of the structure is close to 6000 Hertz. The tweeter alone weighs over a Kilogram, but when coupled at high pressure to the poly alloy cabinet, the mass is huge, exerting a level of control over the sound of the tweeter that is beyond compromise.
