Crowley and Tripp to Introduce Roswellite tm Advanced Material into Ribbon Microphone Production

July 20, 2007: Crowley and Tripp to Introduce Roswellite tm Advanced Material into Ribbon Microphone Production.

The new nanotechnology-based materials provide properties that have previously not been possible with conventional composites and alloys. Roswellite
tm is a unique acoustic nanomaterial that has numerous applications in medical ultrasound and sound recording equipment, such as ribbon microphones, which the company currently manufactures in its US facility. Crowley and Tripp Microphones, along with Soundwave Research Laboratories, Inc., will be commercializing certain products containing the technology beginning in 2007 and will be offering licenses to the technology, supply agreements, and other rights to qualified manufacturers.

Hello Bob,

Will you be updating all of your products with this new technology or will it be reserved for a New Microphone or microphone types?

Thanks
Peace
Marco

Hi Marco,

It is not a direct, drop in replacement. There are some other things that have to be changed to get optimal performance, which we are still exploring. I expect it will take time for this to develop, since there will have to be some experience with it, also the cost is high, so we aren't going to switch over or discontinue anything.

Last and most important, the human ear will be the final judge.

As an experiment we are also trying this material in other mics as well, to see how much has to be changed to make it go. One thing for certain, it is strong and can take a windblast directly, mashing the ribbon right up against the screen, and it pops right back. Same with a TRS error or the like, it just returns to shape, which is the idea. Yesterday I was experimenting with an old Shure 333 and one version of the the new material, of which there are several.

The mass is actually slightly less, so the transient response ringdown in the high end is even faster (already it is very good) and at least as good at bass frequencies. Since it can be designed with such a big excursion, it opens up other interesting possibilities in design too, so stay tuned and let's see what happens. I'm very pleased with the development progress, we're doing life testing now, and we plan to have this available in a product this year. I guess the cost is going to be an important factor, as it is very expensive to make, but once it is made, you don't have to redo it.
