Crane Commander Speaker (pair)
Crane Commander — Dual-Driver Authority. Horn-Loaded Finesse. High Sensitivity.
Big dynamics, beautiful tone, and a level of ease that feels almost effortless.
What This Speaker Solves
The goal: Deliver deep, effortless bass, expressive midrange presence, and horn-loaded realism in one unified system — without the strain that can appear when a single driver covers too much of the spectrum at once.
Why This Problem Happens
When music becomes dynamic, a single driver must move farther to create bass. The more it moves, the harder it becomes to maintain midrange clarity and articulation. Excursion demands increase, and subtle details can soften or blur.
Our Solution
Crane Commander uses two Mark Audio Alpair 12P extended-range drivers in a precisely tuned 2.5-way system. The lower woofer handles bass only (below ~500 Hz). The upper woofer covers bass and low mids, handing off smoothly to the horn. This division of labor dramatically reduces excursion, stabilizes the spectrum, and preserves midrange purity.
Why It Works
By sharing bass duties and isolating low-mid energy to the upper driver — which sits closer to the horn — the system gains the ease, scale, and grounded authority of a large-format design. Meanwhile, the paper cones maintain tone, immediacy, and lifelike presence. The horn-loaded high-frequency section then completes the spectrum with clarity and effortless top-end extension.
Your Result
A presentation that feels big, relaxed, and controlled — with grounded bass, articulate mids, and a horn-loaded top end that adds realism, width, and effortless detail at any listening level.

Cabinet Construction & Joinery
All Shinjitsu Audio cabinets are made from ¾″ Baltic Birch — never MDF.
Its 13-ply structure provides superior rigidity, damping, and long-term stability.
Rabbet Joint Strength
- Increased glue surface for maximum adhesion
- Mechanical interlock keeps panels square and rigid
- Self-aligning for perfect cabinet fitment
- Used in fine cabinetry and precision enclosures
End-grain visibility is intentional — a mark of real joinery, not veneer.
Why We Don’t Use Veneer
Veneer is thin (≈0.5 mm), fragile, and difficult to repair cleanly.
Baltic Birch’s outer ply (≈1.5 mm) is durable, refinishable, and built to last.
