engineered, and manufactured for Revel loudspeakers.
Revel engineers use Computer Aided Design (CAD) software to
design transducers that are optimized for each Revel model. A powerful
Finite Element Analysis (FEA) system provides a comprehensive computer
simulation of the entire driver assembly, allowing engineers to optimize
every aspect of a transducer assembly. FEA produces precise models of
the driver’s magnetic system, which is used to optimize the electro-mag-
netic circuits for each transducer according to the individual driver’s appli-
cation. Transducer components such as cones, domes, surrounds, and
centering mechanisms (the spider) also benefit from FEA scrutiny in the
design process.
An in-house Stereo Lithography Apparatus (SLA) is used during
development to help assure very tight tolerances and minimize develop-
ment times. The SLA utilizes a high-power laser to precisely solidify a liq-
uid polymer into the 3-dimensional shapes specified in CAD drawings.
This allows designs to be turned in real prototypes very quickly so they
can be verified before going into production.
During development, Revel also uses the industry’s most sophis-
ticated driver distortion analyzer to pinpoint the precise source and loca-
tion of undesirable distortions within the driver assembly. In addition, a
high-resolution Laser Interferometer scans the entire radiating surface of
the driver for evidence of breakup, which occurs when the radiating sur-
face flexes undesirably. This incredible tool helps Revel drivers to achieve
more linear piston-like behavior, delivering minimal coloration and excep-
