SW312TU01     12 alu-cone car subwoofer, 4 ohm

SW312TU01 is a 4 ohm  woofer designed for dedicated automotive subwoofer applications.
The extremely stiff aluminium cone, the long linear throw, exaggerated ventilation, and the special dynamic linearization short circuiting rings together makes up for an unusually linear and low-distortion woofer. Even at very high signal levels, the unit behaves controlled and without distortion.
Due to low mechanical losses SW312TU01 masters equally well low level details and extreme dynamic requirements.
SW312TU01 features an additional spacer that prevents the voice coil from bottoming even if pushed extremely hard in high-SPL competitions.

FEATURES

SW312TU01-photo
  • Extremely rigid aluminium cone to ensure piston motion at high levels and for better heat transfer at high continuous power levels
  • Die cast alu chassis with additional spacers for optimal ventilation and increased stroke
  • Vented cone neck for reduced distortion and compression
  • Vented chassis for lower air flow speed reducing audible distortion
  • Heavy-duty black fiber glass voice coil bobbin to reduce mechanical losses resulting in better dynamic performance and low-level details
  • Large motor system with 2” voice coil diameter and 155mm magnet for better control and efficiency
  • Black-anodized magnet structure steel parts for increased heat dissipation and power handling
  • Two built-in alu field stabilizing rings for reduced high-level distortion (see drawing)
  • Long linear stroke motor for reduced distortion at high levels
  • Linear suspension with specially designed CONEX damper (spider) for long durability under extreme operating conditions
  • 4-layer voice coil for increased control and better small-cabinet performance
