QUATTROCENTO by Roberto Tognon
A meticulously handcrafted 4-channel Class A/B car audio amplifier designed for music enthusiasts who demand exceptional sound quality without compromise. The QUATTROCENTO delivers reference-grade audio performance in a compact CNC-milled aluminum chassis, making it ideal for front stage configurations, full-range systems, and audiophile SQ builds.
Built by Roberto Tognon in Italy using top-grade components, the QUATTROCENTO is engineered for those who understand that the amplifier is the foundation of a great car audio system. With ultra-low distortion (<0.008% THD), a damping factor exceeding 150, and a frequency response extending beyond 100kHz, it reproduces music exactly as the artist intended — nothing added, nothing lost.
Handcrafted in Italy — In stock and shipping to USA, Canada, and Mexico
Why the QUATTROCENTO?
The QUATTROCENTO fills the gap between entry-level car amplifiers and flagship-tier units. It brings Italian handcrafted quality, audiophile-grade component selection, and Roberto Tognon’s legendary circuit design philosophy to a more accessible 4-channel platform — perfect for powering a full front stage or a mid-bass and tweeter system in a serious SQ competition build.
