description
The LR14 is a passive 2-way line-source loudspeakersystem. It is a true line-array system, to be used asvertical array, either in stacked or flown configuration,
for both portable and permanent installations. Loadedwith the RBN401 ribbon driver on a “Morpher” lens
(up to 94% frontal radiation!), the system features
120° horizontal dispersion with seamless coverage,
due to the ribbon’s all-natural cylindrical (Isophasic)
wavefront. Its transient response and unusual high peak
power handling (800W/200mS) caters for an amazing
intelligibility and throw, while offering maximum “gainbefore-feedback” up to directly under the array.
The ultra-compact size, combined with the weight-saving
all Neodymium drivers, makes the system very easy
to handle.
The “Morpher” is mounted in the “ALrad™” waveguide,
which utilizes the stiffness and heat transfer capabilitiesof aluminium. Mounted on the RBN, the ALrad™ extens
the cooling surface for even further reducing powercompression for increased SPL over time.

The SignalIntegritySensing™ pre-wiring ��������ensurescomplete cable/connector compensation between
the LR14 and ALC. Typical (short to medium throw)
applications for the LR14 include as compact main
system for theatre and A/V or as under-fill in a LR16system. It is available in 90° and 120° configuration.
The system includes dedicated filtering, but system
equalizing is done remotely (electronically) fully utilizing
the individual speaker components’ power capacity.
This results in increased headroom SPL.

In applications where extended bass response isrequired, the LR14 can be combined with a pressurebass (LR14B) or deep-sub system (BF181), or both.
For full system performance, the LR14 needs to be driven
by an ALC controller-amplifier. Driven by the ALC, theLR14 delivers maximum sound quality with inaudible(power and excursion) protection (SDP circuit).
