The SB29RDAC-C000-4 is a 29mm ring radiator tweeter from SB Acoustics featuring a 104mm faceplate. The centre of the diaphragm is inverted and bonded to an internal dimple on the pole piece, this innovation negates the need for a front phase plug and gives excellent extension.
Inverted centre phase plug free design
Non-resonant diaphragm design for minimum high frequency break-up
Dual balanced compression chamber for improved dynamics
Copper capped pole for reduced voice coil inductance and minimum phase shift
Saturation controlled motor system for low distortion
Non-reflective rear chamber with optimised damping for improved dynamics
Flow optimised vented pole piece for optimum coupling to rear chamber
