Grover Notting Speakers in Perth

following on from Frank Hinton's visit to Perth here are some more details about the Grover Notting speaker and amplifier range 

Dear Colleagues,
For several weeks in June we visited old and new client friends in Adelaide and Perth, meeting many passionate and talented individuals, experiencing their craft and sharing their vision.  It reminded me of the fact, no matter where you are skills are the same, it is just a matter of magnitude, everyone is important. Aspects of the journey also reinforced my view, if all people were able to regularly experience well written, performed, produced and presented music, their lives would be enriched and the world would be a more peaceful and moderate place. Therefore, in this issue, we briefly overview the evolution, role and benefits of a valuable life-force, and conclude with an updated short form GROVER NOTTING® technology catalogue.
The Evolution, Role and Benefits of Music

Thanks to sound, music is possible and thanks to music we have at our disposal a universal language that can penetrate any boundary and engage anyone, anywhere. The origin of the word music derives from the Greek mousike which translates as “art of the Muses”. However, music in its various forms was practiced long before the dawn of Greek civilisation. The first musical performance was most likely executed with percussive implements, followed some time later by the practice of tailoring then blowing into hollow reeds, wood, animal bones and horns. Implements made from bone, horn, reed and wood with holes carved sequentially, have been discovered dating back over 35,000 years, and by their design, indicate an understanding of melody. From these times, archaeological findings and other supporting evidence reveal a steady growth in the sophistication of musical instruments, indicating that music has been a coincident aspect of human evolution. Organised music was certainly sung and performed on percussion, strung and blown instruments in ancient Egypt and surrounding cultures of the time, and probably well before this period. The role, influence and nature of music are usually determined by the resident culture of the day, which will change over the passage of time and be subject to intervening events.
Just as the food and drink we consume nourishes and sustains our body, many feel music is the food that nourishes and sustains our soul. Well written, performed, produced and presented music experienced live or replayed, can be both intellectually and emotionally engaging regardless of genre. Irrespective of an individual’s age, gender, race or creed, all can benefit from the therapeutic, recreational, spiritual, educational and career opportunities and benefits provided by music.
The absolute beginning could centre on the womb, where research indicates a benefit to a developing embryo experiencing or sensing music. Whilst not learned on prenatal matters, this author understands the soothing and calming affect music in the form of a lullaby has in sending a new born to peaceful slumber. Once out of the cradle and in preparation for their formal education many young children will benefit and relate to music in the form of nursery rhymes. While all individuals, regardless of age will benefit from a music education let’s finish this short journey by identifying the fact that music enhances most aspects of our life. A positive impact is realised in language (reading, listening and speaking skills), mathematics, psychomotor skills, creativity, self-esteem, aesthetic considerations, social skills, general academic outcomes, recreational, celebration, inspiration, motivation, therapy, spiritual, commercial and vocational. A faithful companion, music touches the soul, challenges the brain and stimulates the heart, healing, comforting, entertaining, inspiring, connecting, transporting, informing, daring, providing and rewarding.
Technology Catalogue - As at June 2017

GROVER NOTTING® is a comprehensive peak performance critical listening platform deployed in studio and location recording, mixing, mastering, editing, post production, broadcast, forensic, restoration, test laboratory, recreational/audiophile and installed sound environments. Wholly owned, created and manufactured in Australia, the loudspeaker platform and companion drive/logistic technology are designed on ‘first principles’ in three R&D streams, Acoustics, Class AB power plants and Class D power amplifiers, and presented in two distinct ranges as follows
 The definitive cross reference, immersive, multi-channel audio reproduction technology is designed to replicate the typical sonic performance of domestic entertainment systems. This unique platform enables engineers, producers and artists to cross reference studio mixes to the normal recreational experience. However, by virtue of core design techniques and technologies, the platform has proven ideally suited to multi-channel applications and the immersive sound experience in all formats including large spherical arrays (32 channels and beyond). Aside from application in the production of entertainment program GROVER NOTTING® multi-channel immersive sound systems are successfully deployed in education, test laboratory and for recreational use.

                                    CR-2                             CR-1                       CR-Driver        

CR-1              The unique audio monitor focussed on reproducing the Audio Information Band©
CR-2              The quintessential cross reference audio monitor
CR-11            The full bandwidth 2-way passive audio monitor solution
CR-Driver      The power amplifier purpose designed to drive the CR-1, CR-2 and CR-11
Principal Audio Monitor Series
 A peak performance no compromise platform aimed at achieving optimum reproductive linearity across three ranges in which all models share identical performance characteristics, the only variant being bandwidth and SPL capability. All aspects of creating this series were viewed on merit and without adherence to any current industry practise or formula. This first principle design philosophy saw performance and reliability considerations prevail over fashion, meaningless features, aesthetics or convenience. It also realised new techniques and technology deployed alongside that which is tried and proven.
 A concise family of full bandwidth 2-way passive models, each deploying massive aggregate transducer motor power, and the Bandwidth Extension Module©. Suitable for all current and proposed critical listening formats and available with the optional purpose designed remote Power Plant.
                                                 Code 1.5                              Code 4
