Hiro Junior – Balanced, Bold, and Built to Impress

Big system performance — without the big system footprint.

The Hiro Junior brings the soul of our flagship Horn X2 system into a compact, elegant 28-liter cabinet. Tuned for smaller to mid-sized rooms, it delivers the same dynamic, horn-loaded performance that made the Horn X2 one of the most talked-about upgrades in the DIY and audiophile world.

Key Features

  • Built on the Horn X2’s Acclaimed Engine: Uses the exact same compression driver, horn, and crossover network as the Horn X2 — celebrated for clarity, dynamics, and effortless top-end performance.
  • CHR-90 Wide-Range Woofer: A magnesium-aluminum cone driver from Mark Audio that delivers punchy, extended bass and an open, uncolored midrange — reaching down to ~37Hz in-room.
  • 28-Liter Sweet Spot: Bigger than the Little Hiro, more compact than the full Hiro. The "just right" size for tight spaces without compromising low-end weight.
  • Shinjitsu-Style Crossover: Our proprietary phase-correct network ensures perfect integration between woofer and horn — the same proven design used in every Horn X2 system.
  • Handcrafted Cabinetry: 3/4" Baltic Birch enclosure with a 1/4" hardwood faceplate, available in:
    • Arizona Rosewood
    • Black Limba
    • Figured Walnut
  • Matching Stands Available: Purpose-built stands to elevate both style and performance.

What It Sounds Like
