Power. Authority. Control.
The Performa B15a subwoofer fea-
tures unique Revel advantages that
no other subwoofer provides, for
authoritative low frequency repro-
duction. Featuring a massive long-
excursion, 15-inch driver that is
equipped with an inverted metal
dome that delivers incredible
acoustic output at the very lowest
deep bass registers, the B15a’s
prodigious deep bass capabilities
will do justice to the most explosive
movie soundtracks, as well as the
newest generation of high resolu-
tion music formats, such as DVD-
Audio and Super Audio Compact
Disc (SACD). A built-in 1,000-watt
power amplifier featuring a
tremendous 40% reserve capacity
powers the 15-inch driver, deliver-
ing up to 1.4 kilowatts to handle
the most thunderous special effects
and the lowest musical octaves.
Revel’s extensive research
into room acoustics has revealed
that even a theoretically ideal sub-
woofer would fail to provide accu-
rate deep bass response due to the
fact that the mere placement of
the subwoofer within the confines
of any listening room introduces
significant and degrading response
variations caused by room-induced
resonances.
Conventional subwoofer
crossover frequency and level con-
trols alone cannot compensate for
these inevitable and inescapable
timbre response irregularities.
Therefore, the Performa B15a sub-
woofer is equipped with a sophisti-
cated tuning system featuring a
three-band parametric equalizer
that allows room-induced reso-
nance peaks to be tamed. This
smooths the response dramatically
and delivers tuneful and musical
low bass reproduction without the
boomy and irritating “one-note”
bass response typical of conven-
tional subwoofers. Fully adjustable
high- and low-pass filters with
adjustable slopes are also provided
to allow the B15a to seamlessly
mate with virtually any combina-
tion of loudspeakers with adjust-
ment flexibility beyond what is
typically provided in surround
processors.
The B15a also includes
adjustable spikes for different floor
types and is available in a choice of
elegant wood veneer finishes:
Natural Cherry, Maple or Black Ash.
