Hiro Speaker Builder Series

Reproduce the Hiro Speaker

The Hiro Speaker Builder Series is intended for builders who wish to reproduce the performance, alignment, and design objectives of the Hiro Speaker through the use of the supplied Hiro Acoustic Engine and published enclosure documentation.

The Hiro Speaker Builder Series provides the engineered portion of the loudspeaker including the horn structure, crossover architecture, tuning system, external wiring, and published enclosure documentation.

Builders supply the enclosure, Mark Audio MA200M driver, damping materials, finishing materials, and assembly labor.

When constructed according to the published documentation, builders can expect performance closely aligned with the Hiro Speaker.
