18" PA 18900 Mk1 PRE BY ACR

Features

• Heat Resistant

  • The 4-inch voice coil features sandwich technology (windings inside and outside the former), providing enhanced durability under high temperatures and high power.

  • It uses a non-conductive fiberglass former and the latest wire coating technology, allowing the voice coil/spool to operate even at temperatures above 280°C.

• Robust and Low Compression

  • The new model chassis is precisely designed using die-cast aluminum, offering maximum structural strength while minimizing air compression for improved thermal performance.

• High Stability and Extended Excursion

  • The triple round surround ensures improved stability and allows for greater cone excursion.

  • The non-press conepaper is coated on the front side to enhance weather resistance.

• Optimized Magnet Power

  • The magnetic motor power is determined through FEA (Finite Element Analysis) software to ensure maximum magnetic efficiency.

  • Additional ventilation holes improve airflow and help dissipate excess heat effectively.
