Description
The SB Acoustics SB29RDNC-C000-4 is a 29 mm fabric ring dome tweeter (ring radiator) with a neodymium magnet and compact faceplate, offering wide dispersion, low distortion, and exceptional crossover flexibility in a tight footprint. It’s a premium solution for high-end compact speakers, MTM designs, or narrow-baffle 2-ways where both sound quality and size matter.
✅ What Makes It Exceptional
