The audio evolution
Quadral GmbH represents over 50 years of experience in the hi-fi industry and a commitment to the highest quality standards. Founded originally as a sales company, Quadral has come a long way, consistently staying ahead of the curve by seizing opportunities and having a keen sense for emerging trends.
We’ll take you behind the scenes to show you how this success was achieved and the key steps in Quadral’s history.
Quadral History
We at Quadral started in 1972 as all-akustik in Hanover and developed our first speaker series in the 1970s. With the introduction of TITAN in 1981, we reached a milestone that launched our international success. Since the takeover by Loxone in 2020, we have been shaping the future of audio and building automation together.
1972
Quadral GmbH founded
The former hi-fi distribution company was founded by Hans-Dieter Hoffmann, Helmut Pabel, Horst Enders and Friedel Hofmann in Hanover. Initially under the name ‘All-Akustik’, Quadral started out as one of the largest importers of consumer electronics.

First in-house developed speakers
After having already sold their own speakers under the names “all” and “quand,” a new speaker brand, Quadral, was introduced in 1973.
By the way, the company name is derived from the term “quadraphonic” and the name of the original distribution company, All-Akustik.

Audio solutions with Loxone
Quality and progress make an unbeatable team—just like Quadral and Loxone. Since 2020, together with the building automation specialists, we have been rethinking audio and creating a more comprehensive listening experience through automation.
Imagine a building that thinks for itself, controlling various functions automatically. With Loxone, this is a reality. Whether it’s a hotel, supermarket, or family home, Loxone enables smart automation for all kinds of projects.
With simple installation, intuitive operation, and a system that connects everything seamlessly, the Loxone product range offers a variety of solutions, including audio, to fit any need.
How Does It Work?
Scalable, flexible and universally applicable.
The Audioserver is the centerpiece of Loxone audio installations. It functions not only as an amplifier but also as a central control unit. With simple installation, implementing audio concepts is straightforward and fully customizable to your needs.
Unlocking audio’s potential
We get more out of your speakers. Limiting audio to just music with great sound is an option, but it means missing out on a lot of potential. With the right automation, we maximize what your speakers can do.
At the restaurant
Background music is essential in many businesses, like restaurants. But it should always match the target audience and set the right mood.
How about this: Visitors can enjoy relaxing music in the afternoon, which transitions into lounge music at a suitable volume in the evening. This creates a cohesive listening experience with a distinct sense of recognition. Custom playlists can further strengthen the brand identity. Thanks to user management, only authorized employees can make changes.
What sounds like a dream scenario is actually easy to achieve. Just set up the logic and control it all through the Loxone App—done.
At home
Think audio in your home is unnecessary? After all, a Bluetooth speaker can get the job done, right? But beyond music, audio solutions offer a lot more possibilities.
Imagine a doorbell that plays a custom message, like “I’m in the garden,” or a personalized alarm system that sounds throughout your home in case of fire, water leaks, or a break-in.
It’s all about adding security and convenience for you and your family—easily achieved with Loxone’s audio solutions.
At the hotel
The right music from high-quality speakers is a key element in creating the perfect atmosphere in a hotel, especially in the reception area, where it helps ensure a warm welcome. But audio can do even more. For instance, you can automate the music in the reception area to play only until 11 pm or have music in the restrooms play only when someone is present.
What might sound like a lot of configuration is actually easy to set up through the app and reduces administrative work. Plus, with predefined permissions, only certain employees can adjust the music, helping you protect your brand identity.
Loxone has the perfect products to make your hotel’s audio concept truly smart.
Overview of Audio Features
All these features come with the power of automation. Every feature listed can be automated through the Loxone App. For instance, you can set the doorbell to be audible only until 10 p.m. or have music play only when someone is in the room. That’s what makes us unique.
Music
Clear, but not to be overlooked. With Quadral’s top-notch loudspeakers, we ensure a superior listening experience for all your favorite tunes.
Alarm
Fire, Water, Burglary…
Whether it’s for your safety or your guests’, our alarm function makes sure everyone hears and can respond quickly to any emergency.
Announcements
From “A storm is approaching; please close doors and windows” to spontaneous messages, you can easily broadcast important information to the right people.
Doorbell
Choose from options like “I’m in the garden,” “Please leave parcels outside the front door,” or the classic “ding-dong”—the choice is yours.
Text-to-Speech
The text-to-speech feature allows for neutral statements or announcements in a foreign language, and these can be played automatically as needed.
Easy to Use
Just tap and you’re good to go—audio control can be that simple and accessible. No need to hunt for the right button or dig through complicated instructions to manage your audio setup.
The touch control, available in various models, features five touch points. Traditionally, the two buttons on the right handle music and sound. Use these to adjust the volume, turn the music off, or switch sources, like changing radio stations.
All in One Place
Feeling overwhelmed by managing different rooms with varying functions at different times?
With the Loxone App, it’s simple and streamlined. You can define and monitor automation logic right from the app. Control each room individually, and make spontaneous adjustments with ease.
Want to limit access? The children shouldn’t be able to turn on the music after 9 PM? No problem! With predefined permissions, you have full control over who can manage what and which options are available.

Easy Installation, Invisible Speakers
Ceilings, walls, furniture, or freestanding in the room: With the right installation enclosure, our installation speakers can be used almost anywhere – completely customised to your requirements.
Thanks to the cover, the speakers blend in almost invisibly and provide exceptional sound despite their discreet look.
Coaxial System
In a 2-way coaxial system, a smaller tweeter is positioned at the center of the woofer, sitting precisely in the middle. Both drivers are aligned along the same axis and appear to emit sound from a common point.
The centered sound source not only allows for a particularly space-saving design but also ensures a uniform dispersion pattern. As the frequency response is similar in all directions, the sound character remains consistent regardless of the listening position.
Single Frame Construction
When the enclosure of a speaker is made from a continuous frame, it offers several advantages.
We were able to increase our membrane surface by 50% compared to conventional 7‘’ speakers on the market, which corresponds to a doubling of sound pressure. This design also reduces distortions and enhances efficiency by consuming less energy.
The Audible Difference
The quality and sound of the speakers from our long-established company have been recognized with multiple awards over the years. We are proud that our product range has always been regarded as a benchmark for premium sound in the world of high-end audio.
