OFC Copper

• Purity: at least 99.995% Cu, often 99.999% (4N) or higher
• Feature: almost oxygen-free (typically <10 ppm)
• Result: more stable grain boundaries, less oxide formation, more uniform electron flow

H-Core

The H-Core has a relatively closed magnetic circuit and therefore operates particularly efficiently. For the same inductance, less conductor length – and thus less copper – is required, which is why very low R_DC values are possible in a compact design.

The trade-off is the saturation margin: H-Cores saturate sooner than P-Cores at high currents. When properly designed, the H-Core delivers a very tight, controlled sound reproduction with high efficiency.

It is particularly well-suited when low resistance and space savings are priorities.

Round Wire

Round wire coils are the tried and tested standard design: A solid conductor is formed into a winding and provides an easily calculable inductance. In terms of sound, DC resistance (R_DC) is decisive here because it directly influences efficiency and control — especially in the bass range.

Ferrite HP3616

HP3616 is our precision material for low-signal applications: fast, clean and very compact. Particularly in correction links, equalizers and selected midrange tasks, he shows his strength in clarity and definition.

The design is decisive for high currents in the bass, as the magnetization reserves are limited.

Tight Tolerances

Tight tolerances in capacitance, inductance, and resistance ensure that capacitors of one type are very close together in terms of their electrical properties. In crossovers, the left and right channels therefore work virtually identically: crossover frequencies, level ratios and phase positions match closely. This is the basis for stable, precise stereo imaging and reproducible results — in series production and also after service.

Tonal Effects

• precise, stable soundstage without drifting
• Coherent overall impression: left and right channels fuse into a single, seamless whole
• characteristic sound is reliably retained even after component replacement/repair
• More stable virtual center and clearer spatial layering
