• Real 150 w RMS power handling
• Sensitivity: 97dB @ 2.83v
• 2” (51.7mm) aluminium voice coil.
• Low weight due to the neodymium magnet system
Notes:
*The power capacity is determined according to AES2-1984 (r2003) standard.
Program power is defined as the transducer’s ability to handle normal music program material.
**T-S parameters are measured after an exercise period using a preconditioning power test.
***The Xmax is calculated as (Lvc - Hag)/2 + Hag/3.5, where Lvc is the voice coil length and Hag is the air gap height.
