Description
Engineered for high-resolution car audio systems, the IMP REF AMT uses Air Motion Transformer technology to reproduce upper-frequency detail with exceptional speed, clarity, and openness. Its pleated Kapton diaphragm reveals fine musical textures, natural harmonics, and a spacious soundstage without harshness.
The powerful neodymium magnet delivers precise control in a compact format, making installation easy in A-pillars, sail panels, and other space-limited locations. With an extended response reaching 40 kHz, the REF AMT produces smooth, airy, and sweet treble.
Its wide high-frequency extension also makes it an excellent choice for advanced four-way systems, where it can operate as a dedicated tweeter above a wideband or dedicated mid-high driver. This allows more precise crossover control, improved driver integration, and greater clarity at the top end.
