DESCRIPTION
The REVEL ULTIMA GEM loudspeaker features a unique trans-
ducer configuration (see Figure 2) to create an acoustic center that
is halfway between the two woofers and coincident with the front
tweeter’s acoustic center. A second tweeter (on rear of cabinet),
operating above 8 kHz, provides additional high-frequency energy
to enhance overall “room response.”
Combined with an individually-optimized crossover network, this
transducer arrangement provides a uniform vertical “listening win-
dow” or area in which the sound varies little. Also, the small
woofer size and compact baffle width help to create an extremely
wide horizontal window in which optimum sound can be heard.
WOOFERS
To ensure uncompressed dynamic range, each loudspeaker contains
a pair of 5-inch woofers that are unique in the following ways:
• The woofer’s radiating surface is made of titanium for true pis-
tonic behavior to over 4 kHz, well beyond its function in the
GEM system.
• Optimized magnetic circuits to minimize harmonic distortion.
• The woofer’s motor system utilizes neodymium magnets with a
stray-flux containment system for shielding near video monitors.
• Oversized 2-inch diameter voice coils with flat aluminum wire
offer higher power handling than average-sized coils for greater
accuracy at high volume levels and during extended crescendos.
• The cast magnesium frame provides optimum voice coil cooling
and minimum reflections, while offering excellent rigidity.
