Original price was: €1,714.91.Current price is: €1,200.44. IVA esclusa

The Lombardi LS450AHS is an innovative, high-quality bi-amplified subwoofer, ideal for portable active sub-satellite systems. Entirely designed and manufactured in Italy by Lombardi Amplificazioni, it features top-grade components. The cabinet is constructed from two types of wood: the exterior is poplar plywood, making it lightweight and delivering a warmer sound, while all internal reinforcements are made from birch, ensuring strength and durability.

The LS450AHS houses a 8″ horn-loaded speaker, providing exceptional precision, sound quality, and high pressure in the low and sub-low frequency range, allowing bass to travel greater distances.

The subwoofer is powered in bi-amplification by two Class A/B amplifiers:

  • 450 W RMS / 8 Ω driving the LS450AHS subwoofer

  • 400 W RMS / 8 Ω driving an 8 Ω satellite (we recommend the Lombardi LVR400HP satellite for a complete system)

Each column delivers a total of 850 W RMS.

When paired with Lombardi satellites LV100P, LV60P, or LVR400HP, the system maintains a linear frequency response, providing a complete, versatile performance suitable for any music genre and ideal for both indoor venues and small outdoor spaces.

The true strength of the product lies in its versatility, modularity, ease of use, and lightweight design, making it a portable, highly efficient solution with the signature sound quality that distinguishes Lombardi Amplificazioni products.
A system that truly exceeds expectations.
