DESCRIPTION
The Revel Performa B15a powered subwoofer system features a
unique transducer that combines brute-force capabilities unprece-
dented in home loudspeakers with a new level of low frequency
nuance and refinement. Combined with the huge internal power
capability, the result is a new standard of superb bass performance
and adaptability for home entertainment systems.
SUBWOOFER
To ensure uncompressed dynamic range, each B15a features a
subwoofer with the following attributes:
• A 3-inch (76 mm) diameter, four-layer voice coil with 23 gauge
copper wire is wound on a dual-laminated Kapton former for
extraordinary power handling and freedom from compression.
• Extremely long-throw voice coil is capable of 2.5 inches (64 mm)
of peak-to-peak linear excursion, and 3 inches (76 mm) of maxi-
mum excursion for uncompressed reproduction of deep sustained
bass notes.
• A massive, 130-ounce (3.7 kg) magnet system produces
1.4 tesla of flux in the gap.
• Ultra-rigid Kevlar ® pulp and alloy composite cone with an
inverted metal dome operate as a perfect piston under all
reproduction conditions.
• Modulation rings and a machined “T” pole-piece for extremely
low distortion.
• The heavy wall, cast aluminum frame maintains alignment
between the magnet structure and the moving elements, while
offering excellent rigidity to eliminate basket resonances.
