Hiro Junior (PAIR)
Hiro Junior — Big-Speaker Sound, Compact Form
A full-size horn in a cabinet that fits anywhere.
1. The Problem
Most compact speakers sound… compact. They’re clear enough, but they don’t project scale or presence. Music stays stuck to the box, dynamics flatten, and the excitement of a full-sized system never quite materializes.
2. Why It Happens
Small speakers often rely on small woofers, soft-dome tweeters, and undersized cabinets. These parts do the job, but they can't move enough air to create realism. The woofer pushes, the tweeter tries to keep up, and the system hits its limits long before the music does.
3. The Solution
Hiro Junior uses a full-size horn and compression driver in a compact enclosure. This brings the scale, headroom, and immediacy of a large horn system into a footprint that fits today’s rooms, desks, and listening spaces.
4. Why It Works
Horns excel at one thing above all: dynamic efficiency. A good compression driver can keep up with a woofer — and often exceed it. By pairing a full-size horn with a highly capable woofer and a tuned 2 kHz crossover, Hiro Junior delivers big-speaker presence without needing big-speaker size.
5. Your Result
Room-filling sound, real depth, clean imaging, and clarity that holds even at late-night listening levels. Hiro Junior feels much larger than it looks — exactly as intended.
Design and Components
- Woofer: Mark Audio CHR-120 — smooth, extended, and balanced
- Horn: Full-size B&C ME45 constant-directivity horn
- Compression Driver: Beyma CD171 FE/PK — natural, detailed, effortless
- Crossover: 2nd-order network at ~2 kHz for a seamless handoff
Cabinet Construction & Joinery
Every cabinet is built from ¾-inch Baltic Birch plywood — never MDF. Its multi-layer cross-grain structure offers superior damping, strength, and longevity.
1/4-Inch Solid Exotic Wood Front Baffle
Each face is cut from a single slab of hardwood, hand-sanded and finished. Current and rotating species include walnut, padauk, oak, wenge, black limba, and many more. Email or call for availability.
