Description
The LS450AHS belongs to the Lombardi active systems family, sharing the same design philosophy as the larger LS950AHS: delivering real performance, analog control and system flexibility.
Compared to the LS950AHS, the LS450AHS offers the same architecture in a more compact and lightweight format, making it ideal for applications where space and transportability are critical.
Horn-loaded technology and real performance
The horn-loaded design allows the LS450AHS 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 application, both indoor and outdoor.
Integrated bi-amplified system
The LS450AHS integrates an internal amplification system designed to manage:
• the subwoofer
• a second power channel
Main configurations:
• Top mode (high-pass)
driving:
– LVR400HP
• Sub mode (low-pass)
driving an additional passive subwoofer LS450P
This configuration allows the creation of extremely compact complete systems.
Lombardi analog technology – signal control
The LS450AHS features a fully analog signal management system designed to ensure sound quality, protection and real system control.
Dual optical limiter system
• Input limiter
levels the incoming signal to prevent distortion
• Output limiter
maintains maximum output level without distortion, protecting the system
This approach provides real signal control and effective protection without degrading sound quality, preserving the dynamics, natural response and musicality typical of Lombardi analog systems.
Flexible signal management
• mono operation (input A)
• or stereo operation (inputs A + B)
• selectable via switch
Dual amplified output configuration
• Top mode (high-pass) → LVR400HP
• Sub mode (low-pass) → LS450P
with operation modes:
• mono
• stereo
Analog equalization
The system includes a fully analog equalization circuit, designed to:
• enhance low-frequency response
• increase bass presence
• maintain a warm and natural sound
Ultra-compact design and portability
The LS450AHS is one of the most compact solutions in the Lombardi range.
Thanks to:
- compact dimensions
- reduced weight
- high efficiency
it can be easily transported even in simple logistical situations, making it ideal for mobile audio services and quick setups.
Integration with Lombardi systems
The LS450AHS integrates perfectly with:
• LVR400HP
allowing the creation of extremely compact sub-satellite systems.
Lombardi philosophy
The LS450AHS follows Lombardi’s philosophy:
👉 real performance over commercial compromise
delivering:
- analog signal control
- high efficiency
- professional construction
- warm, precise and musical sound
The LS450AHS is not just an active subwoofer, but a complete system designed for professional compact audio applications.
