Description
The LS450AS is the amplified version of the LS450P, maintaining Lombardi’s design philosophy: delivering real performance, high efficiency and superior sound quality compared to traditional reflex systems.
Unlike the LS450AHS, the LS450AS is a simpler and more direct system, equipped with a single amplifier dedicated to the subwoofer, designed for applications where ease of use and fast setup are essential.
Horn-loaded technology and real performance
The horn-loaded design allows the LS450AS to achieve:
- high efficiency
- strong sound pressure
- excellent low-frequency control
- fast and precise response
Despite the 8″ woofer, the system delivers performance comparable to larger subwoofers.
The system maintains a linear frequency response across the full range, making it extremely versatile for any musical genre and suitable for both indoor and outdoor applications.
Integrated amplification
The LS450AS is equipped with an internal amplifier delivering:
• 450 W RMS at 8 ohms
The amplification is designed to provide:
- high dynamic response
- reliability
- real control over the loudspeaker
The system is optimized to perfectly match the transducer, ensuring a consistent and controlled performance.
Flexible system integration
The LS450AS can be used as the foundation of compact audio systems and is designed to operate in different configurations:
• pairing with active top speakers
• use within systems with passive loudspeakers (without integrated amplification)
This flexibility makes it highly versatile across different system setups.
System expansion capability
The LS450AS allows connection of an additional passive subwoofer LS450P, lowering the system impedance and increasing overall low-frequency performance.
This configuration allows:
- increased sound pressure
- extended coverage
- consistent tonal balance
making the system suitable for larger applications.
Precision, speed and 8″ design
The 8″ woofer allows:
- faster response
- higher precision
- improved note definition
- tighter low-frequency control
The result is a fast, clear and musical bass response, while maintaining the warm Lombardi sound character.
Lightweight cabinet and Lombardi construction
The cabinet is built using three types of wood:
• poplar plywood (lightweight and warm sound)
• birch plywood (structural strength)
• spruce front panel (optimized acoustic response)
This combination results in a cabinet that is lightweight yet extremely robust.
Compact size and portability
The LS450AS is designed to be:
- easy to transport
- lightweight
- compact
It can be used even in simple logistical conditions, making it ideal for:
- DJ sets
- small events
- mobile audio services
Integration with Lombardi systems
The LS450AS integrates perfectly with:
• LVR400HP
and is ideal for building compact and efficient sub-satellite systems.
Lombardi philosophy
The LS450AS follows Lombardi’s philosophy:
👉 real performance over commercial compromise
delivering:
- high efficiency
- professional construction
- warm, precise and natural sound
- long-term reliability
