25mm Voice coil, Norex paper cone, rubber surround, ferrite motor, aluminium chassis
- Proprietary cone material with natural fibres made in-house
- Shortened voice coil optimised for pure midrange reproduction
- High damping Butyl rubber surround for non-resonant sound character
- Vented pole piece for reduced compression
- Vented cast aluminium chassis for optimum strength and low compression
- CCAW voice coil for reduced moving mass
- Long life silver lead wires
- Non-conducting fibre glass coil former for minimum damping
