Inside the design
Why it’s built this way.
X-pattern array
One woofer dead-center and four compression drivers at the corners of a square baffle. The 4-fold rotational symmetry makes horizontal and vertical coverage identical, and the four HF drivers in coherent series-parallel are designed to add acoustic gain and thermal headroom well beyond a single compression driver.
Carbon-fiber Unibody design
Designed as a one-piece carbon-fiber composite Unibody — a stiff, light shell engineered to push panel resonances clear of the operating band at meaningfully less weight than a comparable plywood or MDF cabinet.
Slide-in service
Every transducer and the passive crossover are designed to ride on a slide-in baffle that pulls out the front face. Service happens at a bench — the shell stays closed, with no glued joints to break.
Multi-orientation rigging
Symmetric fly-points are designed into all four side faces, so the cabinet can hang from any face in any axis; the front-loaded port is intended to keep the acoustic alignment consistent horizontal, vertical, or flown.
