LS808 - Subwoofer -
800w, 18 inch
First choice in passive subwoofers, the LS808 combines an 800-Watt
cast-frame, neodymium-based 18-inch bass driver with a rear-loaded bass horn
enclosure made from 15mm birch ply covered in rugged black carpeting (a black
ultrathane-painted version – LS800PB – is also available). The result is an
exceptionally efficient sub (105dB@1W@1m) with bass response down to 45Hz and
capable of hitting maximum sound-pressure levels of 134dB. Rugged durability
backed by a 2/10-year warranty further ensures years of reliable service.
Inputs include parallel pairs of ¨ù-inch jacks and Speakons¢â . Additionally,
the Speakon¢â connectors are wired to a configuration switch which allows instant
reversal of pinouts for easy hook-ups using optional four wire Speakon¢â cables.
Hardware includes four steel inset handles, a steel top-mounted pole-stand
adapter, a heavy-gauge curved steel grill and tilt-back wheels.
Features
The LS608 and LS808 include flush, top-mounted stand
adapters so that optional speaker poles may be used to mount full range
enclosures above – avoiding the need for separate tripod stands. The
LS608 and LS808 both feature dual, side-mounted, inset carry
handles making it easier for two people to carry them. The LS808,
LS1004 and LS1208 have tilt-back wheels and top/rear mounted
corner handles for better maneuverability and stacking (wheels don't fall in the
handles!!).
élite Series Overview
Yorkville¡¯s élite series loudspeaker systems are the
result of years of research, pushing the limits of modern state-of-the-art sound
reinforcement technology. Engineered for the serious pro audio user, élite
systems are among the most advanced, most versatile and most efficient high
powered portable P.A. boxes available.
Today¡¯s élites, from the highly efficient two-way E10 to the 1500 watt
E2152 have some of the most advanced component protection and crossover
technology available today. They have been carefully designed to bring you the
latest in Yorkville¡¯s advanced loudspeaker engineering.
Ideal for any small PA rental house, installer or sound company, these
loudspeakers may replace a number of specific application cabinets in any
inventory.
A modified
trapezoidal shape and recessed input jack panel and handles mean these cabinets
can function perfectly as a wedge monitor or front-of-house loudspeaker. Unlike
some ¡®multi-function¡¯ loudspeakers currently in the marketplace, great care has
been taken in the design process to ensure that élite cabinets will perform
without compromising functionality as either a monitor or a front-of-house
enclosure. Neither application was considered as an afterthought.
Several of the élite loudspeakers are loaded with 80¡Æ x 50¡Æ rotatable ABS
Waveguide horn assemblies (the E10 utilizes a 100¡Æ x 25¡Æ horn). The
ability to rotate the horn assembly ensures that the cabinet can provide optimum
high frequency dispersion when the loudspeaker is used in either a vertical,
horizontal or arrayed application.
Integrated stand mount adapters and flyware means these enclosures can be
utilized in any permanent install or touring application. In addition, the
modified cabinet shape means the élite series can be installed much closer to
vertical surfaces and in some cases, under balconies in tight locations, and can
be arrayed in a much tighter less obtrusive cluster.
Of course, the élite series has retained the features and high quality sound
that have made them so popular including Yorkville's famous two year (even if
you break it!) transferable warranty.*
Advanced technology
- Compact and simple to operate
- Linear, full range frequency response
- Time aligned with low distortion
- High power handling, high efficiency, high SPL
- High efficiency, high excursion, linear response drivers.
- High definition, high slope internal passive crossovers.
- Computer modeled enclosure designs to accommodate greater driver dynamics.
- Unique protection networks capable of reacting equally to power overloads
and input distortion levels.
- Dual purpose electronic processors specifically designed to enhance bass
response and to act as stereo crossovers when bi-amping with subwoofers.
Advanced Crossover Networks and Protection Schemes
The majority of
the élite range feature seamless driver interaction through sophisticated
high-slope passive networks and ingenious component protection schemes. Rugged
jackplates are inset and include a combination of both Speakon¢â and 1/4" phone
jack inputs.
Advanced PTC¢â Horn Protection makes its debut in the élite series.
PTC¢â is an ingenious current sensing / self resetting breaker that
offers some serious advantages over current protection schemes used in many
loudspeaker cabinets. This protection scheme, while always present in the signal
path, remains inaudible until it becomes necessary for it to react. It kicks in
at a point where it effectively reduces output to the horn and protects that
diaphragm from damage due to excessive power input or signal distortion. Unlike
a breaker it does not require a physical reset to allow signal back to the horn
driver, and unlike a bulb or fuse, does not need to be replaced if the circuit
is tripped, and the fuse is blown.
Where PTC¢â shines
is in heavy feedback environments where most horn diaphragm damage occurs. In
rare situations even where a microphone might be dropped in a monitor, the
sustained ¡®squeal¡¯ can destroy diaphragms in seconds. PTC¢â will significantly
reduce output level to the horn to protect the diaphragm. When the situation has
been rectified, and the feedback eliminated the horn will return to full
operating level within half a second.
The E2152 features the ATP¢â (Active-Transistor) protection system,
which allows the horn driver to operate at levels significantly above those
required for normal operation. The ATP¢â brickwall element of the protection
circuit uses power transistors configured to operate linearly yet have the fast
attack required to protect against harmful transients. Along with ATP¢â, the
crossover also incorporates air core coils and polypropylene capacitors to
guarantee reliable and distortion free operation at extreme levels. The sonic
benefit is higher output and greater transparency when operating at high levels.
élite Series Characteristics
Processor Controlled
Full function stereo analog processors
that are configurable for passive or bi-amp operation, as well as live or
recorded music applications make sure that your élite system is always tuned and
ready.
Rugged Driver Mounting System
All élite cabinets feature a
specially reinforced driver mounting system that makes sure the horn drivers
will still be attached to the horns when you get to the show. The ABS or
composite horns are pressure fitted to the driver which is bolted to the
internal driver support.
Custom Design Horns
Custom ABS plastic and composite horns are
specifically designed for each cabinet and manufactured right in our factory for
optimum quality control. This insures proper waveguide output for better clarity
and lower distortion.
Rugged Black Carpet
Covering
The stylish yet practical carpet that covers the élite cabinets
keeps them looking great. The two part rubberized glue that is used to attach
the carpet ensures that élite cabinets will stand up against moisture by
effectively wrapping the cabinet in a rubber glove.
Curved Metal Speaker Grilles
Curved metal grilles absorb shocks
evenly to resist dings and dents while eliminating frequency resonance. The
trapezoidal cabinet shape allows for arrayable performance without phase
cancellation.
Recessed Handles
All élite cabinets feature attractively recessed
bar handles. Great care is taken to make sure that they "stay out of the way",
but are easy to get at when you need them.
Flush Mounted Stand Adapters
Flush-mounted stand adapters in the
top of the subs and bottom of the full-range speakers allow the use of the
adjustable SW-TELETUBE option which makes setup a breeze by eliminating
the need for speaker stands.
Integrated Wheels
Tilt back wheels and top-mounted handles are
standard issue on the larger cabinets such as the E215, E2152,
LS1208 and LS1004.
