Firewall Robusto DIY – Single Unit (User-Soldered Installation)

The Firewall Robusto DIY version is a unique no-capacitor, no-inductor solution for today's noise-laden world. The solution’s efficient nature reveals itself immediately as an obviously lowered noise floor, and then, over time, in an ever-growing and blooming naturalness of sound quality. A cleaner, clearer picture emerges as the music’s inherent dynamics flow freely, unrestrained by otherwise ubiquitous electrical pollution.  

• The Firewall Robusto DIY version when used for Loudspeaker signal applications: Unlike Zobel networks, the Firewall Robusto for Loudspeakers produces no voltage difference between input and output across the audio spectrum, and, unlike transformers, does not buzz or hum, nor does it lose efficiency. It is easy to use, and provides a huge sonic upgrade. It is compatible with any loudspeaker type.
• The Firewall Robusto DIY version when used for power applications:  Unlike traditional filtering methods, the Firewall Robusto produces no voltage difference between input and output, and, unlike transformers, does not buzz or hum, nor does it lose efficiency. It is easy to use, and provides a huge sonic upgrade.

These predecessors to The Firewall paved the way for the development of the significantly higher-performing Firewall Robusto. At its core is a highly refined 6 mm² copper conductor. Whereas earlier Firewall designs employed parallel bars, the Robusto refines the design to a single bar, without introducing any dynamic bottlenecking whatsoever.

Firewall Robusto is substantially larger than LessLoss's previous Firewall for Loudspeakers DIY products, although it is shorter than the longer models. It is also considerably heavier than all previous versions.

Due to its size and weight, Firewall Robusto  is not suitable for suspended applications, such as the Firewall 640x Plug-and-Play units. Instead, it is designed for installation in equipment that rests on a shelf or on the floor, such as a power distributor or another stationary component.  Try it and be glad!
