About Us

Australian owned and made high end active speaker systems

SGR Audio design and manufacture a range of high-quality audio products, but we are probably most well known for our active loudspeakers.

In addition to the products we make, we have choosen to supply a number of other brands which compliment our own high-end product range. This allows us to offer complete audio solutions, from source to speaker!

SGR Audio are a proud sponsor of the Mad About Audio and Stereo.Net forums.

SGR History

SGR Audio began as a Melbourne based father and son initiative to deliver world class audio excellence. Harry Ralston, the father, has been involved in the audio industry for over 40 years. Stuart Ralston grew up surrounded by audio equipment so it came as no surprise when he followed in his father's footsteps. Now Harry and Stuart are an inseparable team combining the best of both generations. Harry's strong business values and extensive industry experience proved the perfect match for the advanced electronics knowledge, the exposure to modern technologies, and the fresh insight that Stuart's youth brings.

SGR has spent the last 10 years working quietly behind the scenes with a small loyal fan base to perfect its product range. The strength of these products has recently secured SGR distributors in Brisbane, Canberra, and New Zealand. In early 2010, a state of the art R&D and manufacturing facility was set-up in Templestowe, Melbourne, and now that the bulk of the design and infrastructure work is behind them, SGR is making its public foray to showcase an impressive range of active speakers, electronics, and equipment racks. With this full featured and fleshed out product range, SGR is excited about its potential to increase the reputation of Australian HiFi locally and internationally.

Our Mission

SGR was founded on a passion for music and audio reproduction. It is our mission to uphold and share this passion in all that we do. To this end, we seek to provide:

• Value for money
• Easy decision making
• No nonsense, no tom foolery, no snake oil. Only honest sonic improvements easily verifiable by listening tests and science.
• Highly functional and easy to use components.
• Superior service.
• High levels of build and design quality.
• Increased recognition of Australian products on the international stage.

What makes SGR different?

We can objectively tell you about our technical excellence, our achievements, and our design goals or principles. However, the real test lies in the final listening tests with your music. To this end, we kindly invite you to come and audition our products and hear for yourself what makes SGR so special. With so much to gain and nothing to lose, why not come and have a listen? Even if you decide to walk away empty handed we're still happy to have had a chance to share our knowledge and passion with fellow enthusiasts. We don't just offer great service, we also offer hospitality. You are cordially invited to participate in the SGR experience.

Family Owned and Australian Made

By purchasing from SGR, you are supporting local Australian industry. SGR operate out of a high tech production facility which employs a team of highly skilled workers in addition to the large amount of work it outsources to other Australian businesses. In addition to supporting the local economy, by buying from SGR, customers get direct access to the designers of the product. All Melbourne demos are run by the designers themselves allowing customers to get direct answers to any questions they might have about the products or any other general audio topics. And for anyone interstate, they are only a phone call away!

Engineering Excellence

SGR uses the latest in materials science and technology to create products that push the boundaries of audio reproduction and are truley world class. All products are designed to last and thoroughly tested to ensure performance standards are met. We have invested heavily in CNC machinery, electronic and acoustic test equipment to make all this not only possible, but also repeatable with high precision.

Exemplary Customer Service

At SGR, we pride ourselves on the service quality delivered to all customers. We strive to go above and beyond throughout the sales lifecycle, from presales home demonstrations to full installation and optimisation all the way through to future upgrade guidance.

Active Systems

SGR specialises in active speaker systems. Active speaker systems use a separate power amplifier for each driver in a speaker. These amplifiers come after the speaker crossover so the amplifiers are connected directly to the driver, avoiding a number of issues including all the distortion mechanisms associated with passive components in a typical loudspeaker. Active systems allow the best possible control of each driver and ensure optimal amplifier and speaker matching. Our speakers sound as linear and are just as enjoyable at low volume as they are at high volume, this is only achievable by using active technology for very important technical reasons. Feel free to give the designer, Stuart, a call and ask him why active loudspeakers are such a quantum leap forward in performance...

Strong Business Ethics

At SGR we uphold a very strong code of business ethics. We will always support our customers and stand by our products. While we are extremely proud of our products, we operate a friendly no pressure sales environment. We realise that the final decision is up to you and you will purchase if and when you are ready. We take a patient stance with all customers and provide as much help as possible without rushing or pressuring the decision making process.
