The SPH-130 is a high-quality 5.5" hi-fi bass-midrange driver designed for detailed and dynamic audio reproduction. Featuring a specially coated paper cone, optimised rubber surround, and an extended linear radiation range, this unit is ideal for 2-way systems and D'Appolito configurations. It also performs exceptionally well as a dedicated midrange driver in complex multi-way speaker designs.
Built with a lightweight aluminium voice coil former and a powerful magnet structure, the SPH-130 ensures precise transient response, low resonance, and high efficiency across its operating range. Whether used in custom speaker builds or high-fidelity upgrades, it offers professional-grade performance in a compact size.
