H1530 3-Driver Horn Speaker Kit

High-efficiency 3-way horn speaker kit with 15-inch woofer, compression horn midrange and Alnico tweeter.

4100 US $ per pair

Drivers only — enclosure not included

A complete 3-way horn platform

The H1530 combines three dedicated elements into one balanced system foundation: a 15-inch woofer for bass and scale, a horn-loaded compression midrange for dynamics and projection, and an Alnico compression tweeter for extension and detail.

The crossover points are set at 800 Hz and 4500 Hz, allowing each driver to work in its most natural range while maintaining clarity and continuity across the spectrum.

At the foundation of the system is a 15-inch woofer with dual paper cones and cloth surround, chosen for its natural tonal character and ability to move air with ease. With a resonant frequency of 30 Hz, it reaches deep into the low end while keeping bass full, physical and controlled.

The midrange uses a 50 mm compression driver coupled to a horn, bringing speed, focus and dynamic projection to the critical vocal and instrumental range. The high frequencies are handled by a 38 mm Alnico compression tweeter, adding air, precision and a more refined upper register without losing the energy and immediacy of the system.

Built for dynamics, scale and coherence

The H1530 3-Driver Kit is designed to combine the scale and weight of a 15-inch woofer with the speed, presence and projection of horn-loaded compression drivers.

Rather than chasing complexity for its own sake, it brings together three dedicated drivers into a complete high-efficiency platform intended for custom loudspeaker projects.

With a sensitivity of 97 dB, the H1530 works especially well with tube amplifiers and other low- to medium-power systems, while still offering the headroom and authority expected from a large-format speaker concept.

This version is offered as a driver kit only, giving builders the freedom to develop their own enclosure and final implementation.

Designed for custom high-efficiency systems

For DIY enthusiasts, cabinet makers and experienced builders, the H1530 kit offers the essential acoustic core of a large-format horn speaker while leaving full freedom over cabinet design, materials, proportions and final tuning.

Its combination of horn-loaded drivers and large woofer allows the system to sound expressive and dynamic without needing excessive amplifier power, making it especially attractive for tube-based systems.
