Vertical Attach Suround Technique (U.S. Patent (Patent Pending))
Rockford’s proprietary surround technique,VAST, provides up to a 25% increase in the speakers effective radiating cone area without complicated installation issues. This design alters the typical design and manufacturing technique by eliminating the large flat glue surface area (the landing) which allows the surround to be shifted for increased cone area. In turn, both nominal efficiency and maximum output capabilities are dramatically improved. |
