frequencies up to 80 Hz while the front firing woofer
extend up to 400 Hz; the midrange driver reproduces the
frequencies from 400 to 4 kHz. The crossover used in your
LOHENGRIN II is a mix of 1
st . order between the woofer
and midrange units and 3 rd . order between the mids and
high frequency units.
Just like all Verity Audio loudspeakers, The LOHENGRIN II
works with the room reinforcement characteristics to
produce quick and solid bass performances. Despite its
relatively small size, the LOHENGRIN II loudspeaker
provides a low frequency extension down to 16 Hz.
The midrange woofer unit has been optimized for
maximum cone rigidity without breakup resonance. This
special unit is offering a low level of distortion, extended
dynamics range, high-power handling, and simple dividing
network.
Lohengrin II integrates Verity’s own designed and
manufactured ribbon tweeter. This tweeter gives extended,
natural and resonance free reproduction of the harmonic
content of all musical instruments. These units have been
integrated with a very carefully designed crossover that
allows each driver to deliver its full potential. Moreover, all
components used are carefully computer-matched and
indexed to enable optimum sound staging performance.
Packing and Unpacking
Before they left the factory, your LOHENGRIN II cabinets
passed an exhaustive quality control procedure to guaranty
their genuine state. Please observe carefully the following
unpacking instructions for maximum product safety. Once
your LOHENGRIN II cabinets will be unpacked, inspect
them carefully for any physical damage. If any transit
damage can be noticed, please notify your dealer
immediately and request the carrier’s name so a written
claim can be initiated.
Your LOHENGRIN II comes packed in four ATA (Air
Transportation Association) approved flight cases with all
the necessary protection accessories. For transportation
purposes, we strongly recommend you to keep and store
all your packaging
hardware.
Unless the carrier is notified promptly and all the shipping
cases are available for inspection, the right to claim can be
forfeited.
Installation
This section depicts how to assemble and connect the
LOHENGRIN II loudspeaker.
To identify a proper location for the installation of your
LOHENGRIN IIs, please refer to the Room Placement
section of this manual or follow the recommendations of
your dealer.
Once the speakers are properly installed, connect them to
your amplifier by using quality speaker cables. Make sure
that polarities are respected at both ends and that your
cables are installed in the proper direction. The positive
input is identified by a red dot located on the connector
plate.
For vacuum tube equipment that has multiple output
impedance taps, the four-ohm taps should provide the
best interface with the LOHENGRIN II.
Room Placement
Indoors, acoustic intelligibility is of great concern for a
variety of reasons. It requires low background noise levels
and “good” acoustical design. In any room, the reverberant
sound pressure level increases as the acoustic power
increases and decreases as sound absorption in the room
increases and / or sound power flows from the room. The
sound field in a room is composed of two parts, the direct
field and the reverberant field.
The complex theories of physical acoustics, the
uncertainties in predicting the property variations of both
natural and manufactured room materials, and the none
negligible effects of painting, sealing, bracing, furring, and
draping all keep the specification and prediction of room
acoustics from being an exact science. Adding together,
loudspeaker characteristics, the auditory personal taste
and ergonomics make, by practical means, the equation
impossible to solve. The frequent need to evaluate the final
result by listening rather than by purely quantitative
methods gives acoustical tuning a somewhat subjective
aspect.
Nevertheless, knowing what the LOHENGRIN II is capable
to do will be your major asset in establishing the best setup
for your loudspeaker. Here are a few simple rules that will
guide you. A good setup will give you fast transients from
bottom-end to top-end, proper image height and a wide
and deep soundstage.
The following guidelines are based on our own experience
with the LOHENGRIN II. We recommend you to start with
these and later on (after getting familiar with your
Over tightening the connectors could cause
permanent damage.
