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.

Note: on axis frequency response measured with loudspeaker standing on infinite baffle in anechoic
chamber, 1w @ 1m.
