Rockford Fosgate Announces RFTECH:Woofer BoxAdvisor

14 years, 11 months ago Rockford Fosgate, Tempe, AZ, USA

Tempe, Ariz. - Rockford Fosgate is excited to announce the car audio industry’s first online woofer enclosure recommendation and modeling application called the RFTECH:Woofer BoxAdvisor.  Two modes are available; Consumer Mode for basic information and Dealer Mode for advanced charting.

“Authorized Rockford Fosgate Dealers can plot either theoretical or real in-car acoustical transfer functions,” says Drew Kallen, Rockford Fosgate’s Director of Loudspeaker Design.  “Typical speaker modeling applications generate “free-field” response plots, so we know it is important to show dealers the difference in bass response when woofers are placed inside a vehicle”.

Erik Gundersen, Rockford Fosgate’s Director of Advanced Products adds “The BoxAdvisor also uses our core software engine used internally for Rockford Fosgate’s New Product Development testing and validation process.  The similarity in algorithms means a dealer sees on-screen what we see in the laboratory!”

“Customers spend a lot of time downloading PDFs to see what box designs are available, and the BoxAdvisor replicates this data in an easy-to-use web based interface,” explains Eric Russell, WebWizard and Technical Writer for Rockford Fosgate.  “The application is very functional due to AnyChart’s dynamic flash charts and gauges with real-time updating using a Web 2.0 (AJAX) interface”.

In Consumer Mode, the BoxAdvisor displays Enclosure Preference and Amplifier Power Range gauges along with Recommended Sealed, Vented and Infinite Baffle configurations.  Up to 4 woofers are supported with export options to the BoxWizard for customizing box shape and WiringWizard illustrating woofer wiring.

In Dealer Mode, the BoxAdvisor allows you to configure the acoustic properties of the automobile environment.  A vehicle database contains real transfer functions that plot the cabin gain of automobiles.  For unlisted vehicles, manual configuration is possible by specifying Vehicle Size and Air Leaks qualities for a theoretical curve.
