KEY FEATURES

THIELE-SMALL PARAMETERS***

Notes

:

*  The  power  capaticty  is  determined  according  to AES2-1984  (r2003)  standard.  Program 
power is defined as the transducer’s ability to handle normal music program material.

** Sensitivity  was measured at 1m distance, on axis, with 1W input, averaged in the range 
1 - 7 kHz.

*** T-S  parameters  are  measured  after  an  exercise  period  using  a  preconditioning  power 
test.  The  measurements  are  carried  out  with  a  velocity-current  laser  transducer  and  will 
reflect the long term parameters (once the loudspeaker has been working for a short period 
of time).

**** 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.
