Searching for Speakers for low frequencies (until infrasonic)

Anocs · 3rd June 2008, 07:24 AM

We need speakers of unusual needs to the hi-fi world. Our purpose for the speakers are following criteria.

- Good sound pressure as deeply down as possible eaven until the subsonic area
- Rapid response, that means no as little delay (groupdelay) as possible
- Small dimensions, for example, to be lashed on the windows frame

By Item 2, the bassreflex speakers are too slow. It ist clear that we have to try to get through the Hub more than the dimensions.
Eaven our criteria are possily idealistic, we're checking out the possibilities the different systems can give us.
