Amplification and Filtering Matter
The PRO-INS6.4 is best suited for use with dedicated amplification and an active or DSP-controlled high-pass filter. Its design prioritizes midrange projection and intelligibility rather than low-frequency output, making proper crossover configuration essential in motorcycle and high-output audio systems.
Build the correct signal path: Motorcycle DSP Processors and Motorcycle Amplifiers.
Built for Tight Installs
With a 1.16-inch mounting depth, the PRO-INS6.4 is designed for fairings, lids, doors, and compact pods where standard midrange speakers will not fit.
High-Efficiency Midrange Output
A neodymium motor and lightweight moving mass deliver clean vocal and midband clarity that stays controlled at elevated volume levels.
