No. 31
De No. 31 en de No. 32 vormen REL’s topmodellen.
Het onderdrukken en beheersen van
kastresonanties door verdere verfijning van de
behuizing door toepassing van 30 mm gebogen
wanden en hardhouten schoren. Het verhogen van
de maximale geluidsdruk en een nog verder
doorlopend laag door toepassing van koolstof
voor de luidsprekerconussen in combinatie met
nog meer versterkervermogen. De No. 31
combineert een 12” woofer met een 900 Watt
versterker wat resulteert in een laagweergave
tot 17Hz (-6dB). No. 32 combineert een 15”
woofer met een 1000 Watt versterker wat een
laagweergave tot 15 Hz (-6 dB) mogelijk maakt.
Via de afstandsbediening kunnen de belangrijkste
instellingen vanuit de luisterstoel worden
ingegeven. De Reference modellen zijn voorzien
van de REL’s unieke ABC afregeling en unieke
Set-Safe overbelastingsbeveiliging. De
kastafwerking is een 12 laags handopgebrachte en
handgepolijste hoogglanslak. De Reference
modellen zijn alleen leverbaar in zwarte
glanslak uitvoering.
No.31 is nothing less than a
pure reference model, sculpted from the flanks
of the remarkable No.32, but using a newly
developed 12″ (350mm) all carbon fiber driver.
Every facet of No.31 has been comprehensively
upgraded and refined from its predecessor. No.31
delivers the classic Reference filter used in
No.32, the same dual parametric filters, a
driver that handles three times the power to
deliver a truly thrilling experience.
When Only the Best Will
Do (But You’ve Run Out of Room)
No.31 exists to satisfy the needs of those who
crave the finest yet have space limitations.
Whilst some can afford our flagship No.32 model,
it is larger and deeper than some rooms can
accommodate. How can you best deliver No.32’s
sound quality, build quality, and thoughtful
features with a more compact footprint? Enter
No.31.
Perfection Repeated
No.31 matches No.32’s design stroke for stroke,
yet somehow it manages to look more svelte,
crouching closer to the floor—almost feline in
its grace. The elegant plated handles inset into
an ellipse is retained, as is the string grille
that permits vast amounts of air to explode into
your room without creating noise like cloth
grilles can. No.31 features the curvilinear
radius to the sidewalls that define both its
performance and its character. But the reduction
in visual and actual three-dimensional physical
mass is remarkable. No.31: when the best must be
delivered in a smaller space.
Arrayed for Battle
No.31 permits the same vertically stacked line
array as the ultimate No.32. It delivers
transformative performance that no competitor
has been able to. For those who have been
seeking the ultimate musical and theatre
experience, Line Arrays unlock the final
dimension of system reproduction. Audiophiles
have chased three-dimensional sound for years,
yet they have missed the simple fact that the
height—not the depth—of image is the missing
link. By creating products that are designed to
be stacked 3 (or in exceptionally tall rooms, 5)
units high while retaining individual crossover
and gain control of each subwoofer in the array,
REL has created a masterpiece that finally
delivers what the most experienced audiophiles
have been chasing for the past 40 years.
Amplified Perfection
No.32’s 1,000 watt amplifier also lives inside
No.31, only limited to 900 watts to ensure the
perfect complement to the 12” bass engine within
No.31. This allows the maximum dynamics to be
delivered while ensuring a long, cheerful life
for both components. Here too, the LimitLess
Limiter,™ which permits the amplifier to tiptoe
right up to its limit without audible
compression is part of the magic, conveys a
rhythmically effortless quality. Also, its dual
parametric filters allow precise micro-tuning;
the deepest bass is slightly reinforced, while
the upper ranges of bass can be gently trimmed
to ensure a brilliantly rendered transition from
bass to the main speaker. The electronic design
of the reference range is itself artistry
Drive This
The incredible excursion of the 12” pure carbon
fibre driver allows it to play as loud as its
larger stablemate. Yet, the No.31 possesses the
tactility, nimbleness, and attack that only the
greatest subwoofers have ever been able to
deliver. Also, its sonic signature works in
modestly-scaled rooms and with a vast range of
fine speakers. The driver is accelerated by a
specially wound 3” voice coil driven by a
13-pound magnetic structure; even near its
limits, the voice coil remains solidly inside
the gap. It is this visceral power, coupled with
great delicacy and nuance, that is No.31’s
signature.
Total Control
Take control of your No.31 by grasping the REL
Reference Remote Control. Immediately, you will
be struck by the perfect fit in your palm, the
result of careful thought and numerous
generations of trial-and-error fittings during
prototype development. The second reaction to it
is the awareness of its mass, which conveys its
quality, permanence, and immutability. It tells
you, “I am a thing of substance, of quality. Pay
attention, what you do next matters.” If you
have owned a REL in the past (and fully 90% of
Rel Reference owners are), all the familiar
controls are right at hand, exactly where you’d
want them. High (or low if using active
speakers) level gain sits comfortably to the
right side, the crossover rests in the middle,
and .1/LFE gain is off to the left. Below are
three lovely metal toggle switches handle the
critical setup functions. The remote’s on/off
switch is at the bottom. It is both as out of
the way as possible and remains on once turned
on and in use during setup without being
accidentally turned off. In the middle sits the
phase control. This is used only initially to
determine the correct 0 or 180 degrees of phase.
Additionally, the top access to the Dual
Parametric EQ-marked with A and B—permits the
flattest, deepest bass and, at the other end of
the bass frequencies, the fine-tuning of
crossover behavior. This gives you the perfect
blending of subwoofer to main speakers and any
vestiges of room-generated boom and resonance
can be gently trimmed away. REL’s Reference
Remote reminds you of the perfect butler—always
immaculate, indispensable when called upon, then
quietly set aside until a future time when
perhaps additions or further improvements to
one’s system further require its services.
