About Lenard Audio

Lenard Audio is a design and consulting company specialising in electro-acoustic engineering for almost 50 years.  Starting in the late 1960's, we quickly became Australia's premier supplier of live sound reinforcement equipment and electric guitar amplifiers.  Following changes to the industry structure, John Lenard Burnett began developing specialised systems for studio mastering, later developing a range of fully 4-way active integrated systems for all sound reinforcement environments including domestic, studio, commercial, concert PA and cinema.

 

Recently, the Lenard Audio team lead by John Lenard Burnett developed a set of Audio Application Standards© to enable seamless integration across all music platforms.  We continue to seek industry feedback and support for the establishment of these standards and to help bring about a vital change to the industry and to meet the future demands of the digital distribution methods.

 

Based in Australia and servicing the global market, we are actively seeking opportunities to partner with like minded companies and people with a passion for music and a drive to restore the audio industry back to providing quality sound reinforcement solutions, whether via hardware or the establishment of industry standards.

 

The team at Lenard Audio is also available to consult and advise on acoustics, audio education and areas of specialised sound reinforcement where the demand and requirements are of a higher standard than that readily accessible via usual avenues.

"The team at Lenard Audio aims to provide to the world what has been lost, and return to our homes and entertainment venues the sound of the true nature of real musical instruments, played by the greatest musicians, for both live performance and that which has been captured and remaining forever on recorded mediums.

 

Our mission is; simply - to rid the world of bad sound"

Design principals

All Lenard Audio sound systems are designed as fully 4-way active and are multi applicable across many audio applications including domestic, commercial, professional, studio monitoring, cinema and concert PA.

 

The key principal behind the design of all Lenard Audio products is to replicate the virtual reality of musical instruments; allowing the listener to experience the music as it was recorded.

 

To achieve this, we have simply adhered to the laws of nature and physics; building our systems to enable the musical instruments to behave as they would in the natural world.  A piano can only be a piano; a violin can only be a violin;   a sound system that replicates the virtual reality of musical instruments can only be fully 4-way active and scaled in similar structure to the musical instruments it replicates.    Therefore, the form of all Lenard Audio systems is dictated by its function.

 

Our systems are also built to last a lifetime and are therefore aesthetically designed with this in mind.

John Lenard Burnett

John Lenard Burnett is the founder and lead designer of Lenard Audio.  He started his career at the age of 16 as an apprentice for a company making high-powered instrument amplifiers and PA systems for auditoriums.

By his early 20’s John had established his own company Lenard Audio. At the time, Lenard specialised in high-powered instrument amplifiers and PA systems and quickly became the dominant supplier for bands, concerts and festivals within the Australian market.

By the early 90’s, John was creating system designs focused on music recording, mastering and reproduction by the implementation of 4 way active technology.  This included establishing a revolutionary approach to the way modern cinema and large professional systems are developed.

More recently, John has directed his attention to creating Audio Application Standards to enable sound systems of all sizes; domestic and professional to achieve consistent high quality reproduction of music for all sound system companies to adopt.

His passion and mission to “rid the world of bad sound” has led him to dedicate his life to the improvement of the quality of music though reproduction mediums.  John continues to develop new designs and innovations across all areas of the audio industry as well as maintaining the world’s largest   audio   information    site      education.lenardaudio.com

 “Lenard Audio sound systems are for people who are passionate about music.  The only thing that matters is the music.  The music, the whole music and nothing but the music. The purpose of Lenard Audio is to serve those who create the music and to design sound systems that reproduce the music in the way the artists intended their music to be heard.

_John Lenard Burnett

Fully 4-way active

4-way active refers to the application of dividing the music spectrum into 4 registers;  bass, lower voice, upper voice and harmonics, prior to it being sent to the amplifier and its speaker dedicated to that register, (min. 4 x amplifiers & 4 x speakers per channel).  The total music spectrum is approximately 10 octaves; each register covering 2-3 octaves.

 

When we refer to fully 4-way active, we are making a distinction from products advertised as 4-way active which can be 3-way passive with a separate active sub-woofer or stereo systems that are 2-way active per channel but marketed as 4-way active systems.  To be fully 4-way active, the music signal must be divided by an electronic cross-over prior to being sent to the amplifiers, (dedicated per register).     The divided amplified signal is then sent directly to its dedicated speaker.

 

No acoustic musical instrument or single loud speaker can faithfully replicate the entire music spectrum of 10 octaves.  In order to replicate the full music experience with minimal to zero inter-modulation (sound clutter), 4-way active principals must be applied to sound system design.

Consulting & custom installations

The team at Lenard Audio provides consulting services and custom installations as well as advise on acoustics, audio education and areas of  specialised  sound reinforcement where the demand and requirements are of a higher standard than that readily accessible through the usual avenues.

Present designs

Sarabande

The Sarabande is an aesthetically designed compact sound system created using the Lenard Audio Application Standards©.  The musical performance is identical to the Opal Class systems but to a scale more suitable for a home or small studio environment.

 

The design allows for seamless integration across all music reproduction platforms including domestic, studio mastering, cinema and commercial.

Opal

 The Lenard Opal was designed as a benchmark system for studio mastering, providing seamless integration and transparency across all music platforms including home, commercial, cinema and concert PA.

 

Opals are designed to the boundary to what is technically achievable. Our performance driven approach forms the basis of the Lenard Audio Application Standards© and all other Lenard Audio designs.

Valve Towers

Lenard Valve Towers are a perfect addition to any Lenard Opal or Custom Opal system, for those wanting a sweeter, warmer experience.  Valve Towers can also be applied to conventional audiophile system set ups.

Custom Opals

Lenard Custom Opal systems are created to achieve the limits of what is ultimately possible in sound reproduction for specialised domestic, home theatre and studio environments.

K4 Professional and Cinema

Lenard K4 Professional sound systems are designed for large scale audience applications including live concerts and major arena events.   The K4 maintains precise dispersion for far field projection and the acoustical image remains consistent across large distances.   The K4 design adheres to the Lenard Audio Application Standards© as part of the seamless integration and transparency of reproduction across all platforms.

Reviews

Australian Hi-Fi reviews the Canberra Opals

The art of loudspeaker design is the art of compromise. What size enclosure should the designer choose? It must be transportable, yet big enough to provide suitable bass reinforcement. Should he (for it is almost always a man’s game) design his three-driver system as a three-way system, or provide two bass/midrange drivers? If the latter, should he opt for a D’Appolito drive configuration, to deliver a peerless point-source sound? Or reject that, because this works only on a single horizontal plane?

 

Above all, what driver, cabinet and cross-over design choices should be made when a realistic selling price must be achieved?

" If size still matters, and it absolutely does, then Lenard Audio's giant speakers will be big enough to blow you away "
