Satori TW29R-B SB Acoustics tweeter TW 29 with black front panel. Non-resonant diaphragm design for minimum high frequency. Disassembly, two-piece black aluminum front plate with integrated mechanical decoupling. Double symmetric compression chambers for improved dynamics. Double copper caps for absolute minimum voice coil inductance and minimum phase shift. Saturation-controlled motor system with T-shaped pole piece for less distortion. Non-reflective cast aluminum chamber with optimized damping for improved dynamics. Flow-optimized ventilated pole piece for optimal coupling to the rear chamber. CCAW voice coil for low moving mass. Durable silver wire and low resonance frequency for extended range.
