THE LORELEY MK III

Recintos de Graves independientes 

Compresión de Potencia Liberada

La compresión de potencia, la reducción en el rango dinámico causada por el calentamiento de la bobina de voz, es mucho más reducida que la de los controladores de woofer convencionales debido a la bobina de voz ultraancha, subyacente y la estructura de triple imán que empleamos. El manejo de la potencia también se incrementa en gran medida en relación con los diseños convencionales.

The DDD Driver

Ajuste integral de Cruce

El crossover pasivo incorporado proporciona una amplia gama de ajustes para permitir que el Loreley esté configurado de manera óptima para adaptarse a la sala de audición del usuario. El nivel de alta frecuencia se puede ajustar en un rango de -2dB a + 4dB en 4 pasos y el nivel de frecuencia baja se puede ajustar en un rango de + 10dB a 0dB en 3 pasos. Los puentes de alta calidad en el panel posterior hacen que este ajuste sea rápido y fácil.

Filtro Electrónico Opcional

Aconsejamos que el Loreley sea biamplificado y, para obtener los mejores resultados, debería utilizarse con el crossover electrónico German Physiks. Este ha sido diseñado específicamente para su uso con nuestros sistemas de altavoces. Es un diseño mono dual sin compromiso y emplea transformadores de red duales, rectificadores y bancos de condensadores. Los amplificadores operacionales Burr Brown y Analog Devices de grado audiófilo se utilizan exclusivamente junto con condensadores de filtro ESR especiales. Se proporcionan potenciómetros separados de alta calidad para las secciones de paso alto y bajo en cada canal, y la fase del subwoofer se puede ajustar continuamente en el rango de ± 180 grados. Los conectores RCA y XLR se proporcionan para todas las entradas y salidas.

Gabinetes Acabados a Mano

Los gabinetes Loreley están acabados con el mismo estándar exigente que el Gaudi. Están disponibles en la elección del cliente de chapas de madera dura seleccionadas y adaptadas al gusto del cliente. Estos se aplican cuidadosamente a los paneles de MDF antes de la construcción de los gabinetes. Este método da como resultado un desperdicio de material y, por lo tanto, aumenta el costo de fabricación, pero da como resultado el acabado de grado de mobiliario más fino posible. Una capa de laca de alto brillo está disponible como un extra opcional. Por favor vea  Finishes para más detalles.

Version Especial en Fibra de Carbono 

Una versión bajo pedido especial del Loreley está disponible con un gabinete de fibra de carbono laminado. Los paneles MDF pesados ​​del gabinete están reforzados con múltiples capas de fibra de carbono bidireccional impregnada de resina, que se aplican utilizando técnicas originalmente desarrolladas para la industria aeronáutica. El gabinete está cubierto con una laca multicapa y luego pulido a mano con un alto brillo. Esto produce un gabinete que es inmensamente rígido y fuerte, además de estar prácticamente libre de resonancias dentro de la banda de frecuencias de audio. Esto aumenta aún más el nivel ya muy alto de transparencia alcanzado por el Loreley. Esta versión del altavoz está equipada con controladores DDD de fibra de carbono, que amplían la respuesta de frecuencia a 24,000Hz y el nivel máximo de salida a 120dB.

Prestaciones Top

El Loreley no debería considerarse como el segundo mejor para nuestro nivel de referencia Gaudi. Hasta niveles de escucha bastante altos, el rendimiento del Loreley se acerca al de Gaudi, y en salas de escucha de tamaño medio, se sostendrá por sí solo frente a cualquier sistema de altavoces de cualquier precio.

THE LORELEY MK III

Independent Bass Enclosures

Each loudspeaker has two large independent bass enclosures. These are mounted one on top of the other and are held together by an interlocking collar arrangement. This greatly reduces resonances and also makes the column very difficult to topple. This is a useful safety feature for customers who live in earthquake regions. Each enclosure is fitted with a 12 inch inverted dome driver which has a maximum excursion of 3 inches. Distortion levels are typically a tenth of those of conventional 18 inch sub woofers at comparable output levels. In addition, their acceleration and transient responses are far superior due to the immense magnetic forces generated by the massive rare earth magnets we use and to the very high stiffness of the dome diaphragms. The net result is a system with a very extended and very clean low frequency response, that is also capable of prodigious output levels, exceeding 110dB at 18Hz. 

Freedom from Power Compression

Power compression, the reduction in dynamic range caused by heating of the voice coil, is much reduced over conventional woofer drivers due to the ultra-wide, underhung voice coil and triple magnet structure we employ. Power handling is also correspondingly greatly increased over that of conventional designs. 

The DDD Driver

As with all German Physiks loudspeakers, the heart of the Loreley is the DDD driver.  The contribution this makes to the exceptional level of fidelity achieved by this speaker cannot be overstated.  Nor can we overemphasise the important advantages the DDD driver gives the Loreley over speakers using conventional drivers.

The DDD driver’s very low moving mass enables it to operate linearly over an extremely wide frequency range. On the Loreley it covers the entire range from 180Hz upwards  In a conventional design, this range would be covered by two or even three different types of driver and most importantly there would be a cross over point in the mid range, the area where our hearing is most sensitive.  The DDD driver’s wide operating range allows this vital region to be kept free from the level and phase anomalies that multiple drivers and a necessarily more complex cross over would create. This enables the Loreley to produce very accurate and realistic stereo images.

Another key advantage of the DDD driver is that it is omni directional, so these excellent stereo images can be enjoyed from a wide range of listening positions, unlike conventional designs which have much smaller “sweet spots” due to the tendency of their drivers to beam the sound. This allows a more relaxed listening experience as you don’t have to keep worrying about sitting in exactly the right position.

The DDD driver’s very low moving mass provides the further benefit of exceptional impulse and phase response characteristics and allows it to reproduce both the attack of the music and resolve low level detail very accurately.  This is essential in order to faithfully reproduce the delicate nuances and timbral characteristics of a performance and make it sound like music, rather than just good hi-fi.  The driver’s excellent impulse response also ensures that the stereo image remains focussed and stable, even when the loudspeaker is reproducing complex passages at high levels.

More information on the DDD driver, its development and advantages may be found on the Technology page of this web site. 

Comprehensive Crossover Adjustment

The built in passive crossover provides a wide range of adjustment to allow the Loreley to be optimally set up to suit the user’s listening room.  The high frequency level may be adjusted over the range -2dB to +4dB in 4 steps and the low frequency level may be adjusted over the range +10dB to 0dB in 3 steps.  High quality jumpers on the rear panel make this adjustment quick and easy.

Optional Electronic Crossover

We advise that the Loreley be bi-amped and for the best results it should be used with the German Physiks electronic crossover.  This has been designed specifically for use with our speaker systems.  It is a no-compromise, dual mono design and employs dual mains transformers, rectifiers and capacitor banks.  Audiophile grade Burr Brown and Analog Devices op amps are used exclusively along with special low ESR filter capacitors.  Separate high quality potentiometers are provided for both the high and low pass sections in each channel, and the phase of the subwoofer is continuously adjustable over the range of ±180 degrees.  RCA and XLR connectors are provided for all inputs and outputs. 

Hand Finished Cabinets

The Loreley cabinets are finished to the same exacting standard as the Gaudi. They are available in the customer’s choice of select, hand matched hardwood veneers. These are carefully applied to the MDF panels prior to the construction of the cabinets. This method results in some wastage of material and thus adds to the manufacturing cost, but results in the finest possible furniture grade finish. A high gloss lacquer coat is available as an optional extra. Please see the Finishespage for more details. 

Special Order Version

A special order version of the Loreley is available with a laminated carbon fibre cabinet.  The cabinet’s heavy MDF panels are reinforced with multiple layers of bi-directional, resin impregnated carbon fibre, which are applied using techniques originally developed for the aircraft industry.  The cabinet is coated with a multi-layer lacquer and then hand polished to a high lustre.  This produces a cabinet that is immensely rigid and strong, as well as being practically free from resonances within the audio frequency band. This further increases the already very high level of transparency achieved by the Loreley.  This version of the loudspeaker is fitted with carbon fibre DDD drivers, which extend the frequency response to 24,000Hz and the maximum output level to 120dB. 

Top Level Performer

The Loreley should not be looked on as second best to our reference level Gaudi.  Up to quite high listening levels the performance of the Loreley comes close to that of the Gaudi, and in medium size listening rooms, it will more than hold its own against any speaker system at any price.
