Commentary
High frequency compression driver unit with throat diameter of 25 mm.
2426H is an 8 Ω model and 2426J is a 16 Ω model.
By combining a pure titanium diaphragm with an edge of a unique diamond surround structure, excellent durability and frequency characteristics are realized.
The pole piece is plated with copper to reduce the impedance of the voice coil and increase the high-frequency output.
