Testing

In process testing the solid drive units from Induction Dynamics. Very interesting technology indeed. The drive unit is a small chrome cylinder (2'' dia.) that hooks up through a passive notch filter like any other speaker (positive and negative speaker wire). The cylinder is mounted on a solid surface, any will do, and sound radiates out from the unit.
Surfaces effect the sound quality tremendously. A large solid piece of wood was the winner for overall response/quality with sheetrock and glass a close second. Although the overall quality is not as good as "conventional" speakers keep in mind that these are invisible. There are no speakers to look at, no flush grills to paint and have rust in bathrooms, nothing for your guests to trip over, nothing to dust, nothing to see.
This product, like any specialized product, does give up some sound performance for their zero presence but not any more than other small speaker. My overall feeling is that this technology is an excellent choice for applications where it is needed- and there are many applications where it is needed. Total stealth, second homes, boats, security, covered patios, and conference rooms to name a few.

Sound quality: 3-4 depending on surface
Asthetics: 10
Build Quality: 8
Warranty: 10 (seven years)

New Products

Brough Superior will be testing and reviewing a new product from Induction Dynamics called Solid Drive. This is a cutting edge technology that uses small motors to produce sound through any solid surface. The applications are almost endless, from completely invisible speakers buried in the walls to marine and conference room applications. Results from the testing will be posted in a few days.

Hope everyone had a great 4th of July!
