Description
The 18" model in Dayton Audio's Signature Series subwoofers, designed for deep, accurate bass at high output. It has a rigid anodised aluminium cone, dual spider suspension, a triple-stacked magnet motor and a 3" 4-layer copper voice coil on a vented aluminium former, with extensive venting to limit power compression. Dayton aims it at high-performance home theatre and music systems.
Features
- Rigid anodised aluminium cone with indexed edge for pistonic accuracy and reduced resonance
- Aluminium shorting sleeve, ring and pole cap ensure linear inductance and ultra-low distortion
- FEA-optimised motor with triple-stacked magnets delivers exceptional strength and symmetry at high excursion
- 3" 4-layer copper voice coil on a vented aluminium former for superior power handling and cooling
- Extensive venting through cone, pole piece, spider and gap minimises compression during long sessions
- Dual spider suspension with stitched tinsel leads for precise pistonic motion and extreme durability
