Reva Series: Designed from the ground up to offer state-of-the-art
tonal accuracy and musical detail, Wharfedale Reva has been born out of a
combination of extensive research into unique driver and cabinet technology,
combined with a passion for music. Every part of the Reva speakers has been
developed to work in harmony together - including how the drivers work with the
cabinet. From their proprietary glass fiber weave midrange/bass drivers to the
7-layer piano gloss lacquer finish, Reva Series is stunning inside and out and
will bring excitement to your music collection and home cinema experience.
Three-Way Driver Design: The Wharfedale Reva-4 is a three-way floorstanding
loudspeaker which incorporates a 1" textile-dome tweeter, a 4.5" glass fiber
weave cone midrange driver, and two 6" glass fiber weave cone bass woofers. Finely tuned crossovers guarantee a smooth transition
between the tweeter and woofer with an enjoyable audible experience, both on and
- Textile Dome Tweeter: A new, fine weave textile dome, with
critically damped coating, has been chosen for the 1" tweeter, powered by a
Neodymium magnet fitted with a finned heatsink to reduce dynamic
compression. This unit offers excellent bandwidth, with a smooth response
from 2kHz to above 20kHz, and is mounted on a subtly dished waveguide that
- Glass Fiber Woofers: Musical accuracy and articulation is
carried through to the midrange by a midrange/bass driver cones (one 4.5"
midrange & two 6" woofers) that
incorporates a proprietary glass fiber weave that is naturally self-damping
to reduce and distribute resonances to virtually negligible levels. The cone
is mounted in a special alloy, cast chassis to ensure dynamic rigidity and a
fixed, profiled phase plug ensures a smooth acoustic roll-off to enhance
integration with the tweeter.
Non-Resonant Cabinet: Extensive research showed that coherent
materials, like raw MDF, have peak resonances (particularly in the midrange)
that let sound out of a cabinet at volume levels that interfere with the sound
from the drive units. Not surprisingly, this causes a distinct coloration and
character to the sound of such cabinets. To eliminate this, panel material
comprises of a special lamination of wood composites, reducing the sonic
character of the cabinets to a level where it cannot be heard.
Slot-Loaded Port Technology: The Reva Series also features
signature slot-loaded port technology. The slot-loaded port, which uses a gap
between the plinth and the port exit in the base of the cabinet, aids the
pressure differential between the port and the air in the room, increasing g the
energy transfer and making the system more efficient. Research showed this
removes the unwanted low frequency and high output distortion that is often
found in conventional rear ported speakers. The slot-loading technology also
means the speaker can be positioned near the wall, fitting seamlessly into even
smaller living environments.
Dual Heavy-Duty Binding Posts: The floorstanding loudspeaker has two sets
of heavy-duty binding posts connected by jumper-plates. The binding posts will accept bare
wire (up to 10AWG), pin connectors, spade connectors, & banana plugs (single
only). Using these dual binding posts, you can bi-amp or bi-wire the speakers.
Bi-wiring or bi-amping the speakers provide improved bass & treble performance.
If you decide to bi-wire or bi-amp, you must remove the jumpers between the
terminal posts (failure to do this could result in damage to your amplifier and
- Bi-Wiring: Bi-wiring can provide noticeable
improvements in the overall transparency of your loudspeakers. Run separate
speaker wires to the low & high frequency drivers from a single amplifier
(the upper set of binding posts are for the high frequency drivers; the
lower set of binding posts are for the low frequency drivers).
- Bi-Amping: Bi-amping allows you to use separate
amplifiers for the high & low frequency sections of your loudspeaker for
greater dynamic range & lower distortion. We recommend that your separate
amplifiers have identical gain to preserve the speaker's voicing balance.
Spike Feet & Isolation Pucks: The Wharfedale Reva-4
floorstanding loudspeaker comes with four spike feet for carpet installation.
Four isolation pucks with foam padding are also included to protect your
hardwood, tile, laminate, and vinyl flooring. The spike feet are pre-installed
into the bottom of the speaker cabinet's plinth and are adjustable so you can
level up the speaker. The spike feet can be placed directly on carpet or set in
the isolation pucks to protect hardwood, tile, and laminate, and vinyl flooring.
The isolation pucks add approximately 0.25" to the overall height of the
Placement: Try to position the loudspeakers equidistant
(6.5' to 13') from one another and the main listening position. The speakers
should ideally be positioned so that the tweeters are roughly at ear level to a
seated listener. The speakers should be "toed" or angled (15°
to 40°) into the main listening position.
The speakers can be positioned as close as 2.3125' to 3.3' from a side facing
wall. There should be a distance of at least 0.6875' to 3.3' between the back of
the speaker cabinets and the wall (the speakers' bass extension will improve if
they are positioned closer to a wall or corner).
