Apocalypse Series AP2.7


Quick Specs


  • Midrange for monitors and Hi-Fi
  • Black anodized alum cone for better heat transfer
  • True full-range design with on-axis output to beyond 25kHz
  • Dual neodymium magnet structure for high efficiency and almost ideal magnetically shielding
  • Heavy-duty black fiber glass voice coil bobbinto reduce mechanical losses resulting in better dynamic performance and low-level details



The 2.7" transducers Apocalypse Series 2.7"(4 ohm) was designed especially for car audio, where small size is required while still obtaining sound reproduction without compromises.

Features:


1. True full-range design with on-axis output to beyond 25kHz
2. Dual neodymium magnet structure for high efficiency and almost ideal magnetically shielding
3. Copper cap on center pole to reduce voice coil inductance and to minimize variations in voice coil inductance as a function of voice coil position
4. Black anodized alum cone for better heat transfer
5. Vented voice coil former for reduced distortion and compression
6. Heavy-duty black fiber glass voice coil bobbin to reduce mechanical losses resulting in better dynamic performance and low-level details
7. Large motor with 22 mm voice coil diameter for better control and power handling
8. Low-loss suspension (high Qm) for better reproduction of details and dynamics
9. Conex spider for better durability under extreme conditions
