The secret behind the acoustics at TODOS Restaurant in Gwalior

The secret behind the acoustics at TODOS Restaurant in Gwalior

In the city of Gwalior, known for its growing gastronomic and cultural activity, TODOS Restaurant stands out as a space that combines dining, contemporary design, and a socially focused approach centred on outdoor events and carefully constructed indoor environments. Its layout is divided into two clearly differentiated areas: a spacious terrace that serves as the main area for music and social gatherings, and a more contained interior where acoustics depend directly on the architecture and the constant flow of guests.

This duality makes the installation particularly interesting from a technical perspective. Each area presents its own requirements in terms of directivity, sound pressure level, and tonal stability, necessitating the selection of systems capable of maintaining a coherent listening experience in both environments. To meet these demands, solutions from two of our product families were chosen: JUNO and WCX enclosures for the outdoor area, and BS enclosures in combination with an HR subwoofer for the interior.

The terrace functions as an open stage subject to environmental variations, audience movement, and fluctuating sound pressure levels depending on the type of event. Such spaces require enclosures capable of projecting with controlled directivity, withstanding outdoor conditions, and maintaining tonal stability even during extended periods of use. To address these needs, WCX and JUNO-8 cabinets were deployed, paired with a Marine Grade HR-218/20MG subwoofer, specifically designed for outdoor applications. This combination allows wide-area coverage with controlled dispersion, ensuring intelligibility and stable musical reproduction without the need to excessively increase the overall system level.

In the interior area, the acoustic behaviour changes significantly. The presence of absorptive elements and a smaller volume requires a compact, precise system capable of maintaining a balanced response for music playback. In this space, BS-10 enclosures were installed alongside an HR-218/20 subwoofer, a configuration that provides controlled low-frequency reinforcement and a well-defined sound image without interfering with the audience experience. The birch construction and rotatable waveguide of the BS-10 deliver stable directivity, which is essential in environments where listeners are in close proximity.

The final integration of the system was carried out with the aim of maintaining a homogeneous sonic signature between the interior and exterior. The symmetrical dispersion of the JUNO series, the controlled behaviour of the BS enclosures, and the linearity of the HR subwoofers facilitate smooth transitions between areas, regardless of occupancy or environmental conditions. The system guarantees a stable response under any operational condition, maintaining precise control over directivity and ensuring coherent reproduction even with increased sound pressure levels. This ensures that each area of the space receives exactly the acoustic performance projected in the design, meeting the established coverage and uniformity criteria.

Outdoor installation at Hotel Playa Golf, Mallorca

Outdoor installation at Hotel Playa Golf, Mallorca

Designing a reliable sound system for hotel exteriors requires more than just placing weatherproof speakers around a terrace. It involves understanding the real acoustic and operational needs of each area: how the space is used, how sound behaves in open-air environments, and how to ensure consistent performance over time.

At Hotel Playa Golf, a four-star resort facing Playa de Palma, one of Mallorca’s busiest coastal destinations the challenge was clear. With constant outdoor activity during high season and full exposure to sun, humidity, and salty air, this project called for an audio solution tailored for durability, coverage, and seamless integration into the architecture and daily operation of the hotel.

Installing a professional outdoor audio system in a hospitality environment like this means accounting for multiple uses: background music, events, and live sessions, all in open areas with little acoustic control. Standard sound systems aren’t designed for this level of demand. That’s why equipment selection, layout, and signal processing in this project followed strict technical criteria.

To provide background music across pool areas, terraces, and walkways, JUNO-8T loudspeakers were installed. These compact 8” passive speakers include a 100 V line transformer for low-impedance distribution and deliver a 90° x 50° dispersion, 92 dB sensitivity (1 W/1 m). Designed for permanent use outdoors, they feature a treated plywood enclosure, polyurea coating, and IP46-rated weather protection.

In spaces that demand higher SPL, such as event zones or areas with amplified content, HR-208 loudspeakers were added. These passive two-way speakers include an 8” woofer and a 1” compression driver on a constant directivity horn, offering 96 dB sensitivity and 400 W AES power handling. Their polyurea-coated enclosures and corrosion-resistant steel grilles ensure durability even in harsh weather.

Sub-bass reinforcement is handled by HR-18/10 subwoofers. This high-performance subwoofer features an 18″ driver with a 3″ copper voice coil, delivering a frequency response of 46 Hz to 200 Hz (±3 dB) and a sensitivity of 101 dB (1W@1m). Capable of producing a maximum SPL of 135 dB peak, it operates with 1000 W RMS (4000 W peak) power handling. Designed for omnidirectional coverage, it includes an active crossover and 8 Ω nominal impedance.

A demanding outdoor installation by Sontastic

The installation project, carried out by our technical partner Sontastic, called for a sound system that could provide high-performance audio while maintaining structural integrity under the harshest conditions. The solution came in the form of a fully integrated ecosystem of Lynx Pro Audio products, engineered specifically for outdoor sound system installations.

Strategic selection of Lynx Pro Audio products

The technical approach focused on achieving uniform coverage, high speech intelligibility, and a full frequency response using components designed to perform reliably in challenging environmental conditions.

The system was designed to deliver consistent vocal clarity and even sound distribution across the venue without interfering with the architectural aesthetics of the space. To achieve this, Sontastic integrated three of its most versatile product lines for outdoor applications: the JUNO series, the WCX series, and the HR subwoofers in their MG (Marine Grade) version, all selected for their reliability, durability, and acoustic performance in open-air environments.

Main Coverage: JUNO Series

For the open and semi-covered areas, JUNO loudspeakers in 6” and 8” versions were used. This series is specifically developed for outdoor sound reinforcement. With an IP46 rating and heat-resistant components, JUNO delivers consistent performance even in harsh environmental conditions. Its symmetrical coverage pattern ensures clear sound distribution across wide areas without the need for excessive sound pressure levels.

WCX Series

For areas with more directional needs WCX weather resistant coaxial cabinets were installed. These compact models offer clear and controlled vocal reproduction, reinforcing the sound precisely without interference or disturbance. Their design allows for seamless acoustic and visual integration with the surrounding architecture, which is key for maintaining overall system coherence.

Low-end support: HR-18/10 MG subwoofers

To complete the system, HR-18/10 MG subwoofers were added. Built for outdoor use, these subwoofers feature enclosures, hardware, and electronics designed to withstand humidity, high temperatures, and salt exposure without compromising frequency response linearity.

In open-space audio applications, the goal is not just to produce sound, but to guarantee long-term, consistent performance. It starts with the selection of purpose-built components capable of operating efficiently under extreme conditions, ensuring the durability and integrity of the professional outdoor audio system over time

Outdoor sound systems for beach clubs and terraces

Outdoor sound systems for beach clubs and terraces

During the summer season, venues such as beach clubs, terraces, rooftops or outdoor dining areas require outdoor sound systems specifically designed to operate in demanding conditions. Good-response loudspeakers are not enough: the system must operate stably for hours, with direct exposure to the sun, salt spray, high humidity and sudden temperature changes. In these environments, an installation must be unobtrusive, robust and capable of providing uniform coverage without compromising durability or sound quality.

Professional loudspeakers with weather-resistant version must be constructed of materials resistant to moisture, dust and corrosion. But in addition to physical sealing, it is critical that the acoustic design be optimized for outdoor environments: with controlled directivity, good midrange sensitivity, and performance stability at moderate levels over long days. Lynx Pro Audio offers a number of weather-certified solutions, including the JUNO, HR (MG version) or WCX series all with variants prepared for direct exposure.

JUNO Series: Compact and discreet outdoor sound

The JUNO series represents a compact, discreet and highly efficient solution for fixed outdoor installations. Available in 6 “and 8” models, JUNO combines a lightweight construction with IP46 certification, high-strength polyurea finish and transducers selected for their thermal stability and mechanical resistance. This type of system makes it ideal for restaurant terraces, chill-out areas and installations where visual integration is key.

Installations in terraces, rooftops, and hospitality venues require loudspeakers capable of delivering high sound pressure levels with consistent performance in challenging outdoor environments. The HR series in its Marine Grade (MG) version is specifically designed to meet these demands.

HR MG Series: High performance and Marine-Grade resistance

Solutions such as the HR-218/36 MG subwoofer and the full-range HR-1264/5 MG and HR-1296/5 MG models deliver powerful, high-fidelity sound, making them ideal for long-term outdoor installations where both audio performance and durability are critical.

A common practice in real-world installations is to combine both series. In the Lawn Beach Bar in Bali, for example, JUNO and WCX loudspeakers were used for the wide and discreet coverage areas, complemented by HR MG series subwoofers, thus achieving a balanced system with excellent response across the entire spectrum and without compromising weather resistance.

Another example is the Marina Beach Club in Valencia or the Sundays Beach Club in Bali, where JUNO, WCX and HR loudspeaker systems have been installed, intelligently combining acoustic performance, visual integration and structural strength. These projects demonstrate that with the right technical approach it is possible to maintain consistent sound quality even in demanding environments.

In installations with outdoor sound systems, the acoustic design must be accompanied by a strategic placement of the emission points. The use of a distributed system not only improves the homogeneity of the coverage, but also reduces the disturbance to the environment. The orientation should be aligned with the listening plane, avoiding projecting sound onto reflective surfaces such as glass facades or hard floors. Structurally, the use of specific stainless steel or anodized aluminum hardware is essential to ensure stability against wind, vibration or corrosion.

Operational control and system management

Finally, there is the issue of operational control. In most of these spaces there is no resident technician, so system management must be simple, secure and automatable. The LUKA digital processors allow you to configure the system by zones, set volume limits, apply equalization curves and program on/off schedules. This ensures smooth operation, reduces the risk of overload and keeps the system running reliably throughout opening hours.

Each outdoor sound system project presents unique conditions: from the architecture of the space and the type of use, to the user profile and environmental exposure. There is no standard solution, but there are fundamental principles that apply in each case: the use of systems specifically designed for outdoor environments, a rigorous acoustic design based on technical criteria, and the implementation of high-strength materials that guarantee durability.
