Fulcrum Acoustics Debuts New Subwoofer
Fulcrum Acoustic debuted its dual 21-inch US221 subwoofer. The ultracompact, direct radiating subwoofer is designed with 6-inch voice coils and low-turbulence ports coupled with especially rigid cones that allow the pair of woofers to handle 4,000 watts of long term power.
Fulcrum Acoustic, a new audio technology company in the professional sound reinforcement market, this week debuted its dual 21-inch US221 subwoofer. The ultracompact, direct radiating subwoofer is designed with 6-inch voice coils and low-turbulence ports coupled with especially rigid cones that allow the pair of woofers to handle 4,000 watts of long term power, according to the company.
The US221 provides high impact clarity and solid musicality in an enclosure that is smaller than most dual 18-inch subwoofers on the market, say Fulcrum officials. Measuring 22.4 by 35.1 x 30 inches (HWD) and weighing only 177 pounds, the US221 is suited for live performance venues, nightclubs, AV screening rooms, and low frequency effects in theme parks, as well as for under stage and small cavity applications.
The company says it used an innovative approach to routing the 18 mm Baltic birch plywood that makes it possible for the dual 21-inch woofers to nest perfectly inside the enclosure. "The net result is a subwoofer that provides low frequencies with a very authoritative character in a package that is less than half the size and weight of most competitive products on the market," said David Gunness, chief technology officer at Fulcrum Acoustic, in a statement.
The subwoofer has low-turbulence ports and vibration isolators. The low-turbulence ports are constructed of curved plywood and the design makes use of all available frontal area, minimizes turbulence, and smoothly guides the air flow around the woofers' 20 kg magnet structures, according to Fulcrum. The supplied vibration isolators are medical-grade and constructed of high-compliance neoprene to be are more effective than conventional loudspeaker feet.
For applications that require ground stacking, the vibration isolators may be threaded into any four of the sixteen available M10 mounting points to prevent "walking." When stacking enclosures, the vibration isolators nest in recesses surrounding the mounting points in the cabinet below.
