Description
Features
- Beryllium dome for non-resonant high frequency extension
- Two part aluminium faceplate with integrated mechanical decoupling
- Dual balanced compression chambers for improved dynamics
- Dual copper caps for absolute minimum voice coil inductance and minimum phase shift
- High saturation neodymium motor system with T-shaped pole piece for lower distortion
- Non-reflective cast aluminium chamber with optimised damping for improved dynamics
- Shallow flow optimised magnet structure for optimum coupling to rear chamber
- CCAW voice coil for low moving mass
- Long life silver lead wires
- Low resonance frequency for extended range

- TW29BN-B Cutout & Recess Template (NB Audio) Straight off SB Acoustics' spec sheet: flange outline, recess depth, bolt holes. Scaled from SB Acoustics' drawing, so close but not guaranteed exact: cutout. Check it against your driver before you cut.
