A happy family of five

The pistonic series drivers come in five different sizes to suit various earphone designs and topologies.

Performance


These new receivers are available in dimensions of Ø10mm, Ø11mm, Ø12mm, Ø13mm & Ø14.2mm and are all based on the same “pistonic” diaphragm technology where the piston part is made of a very stiff and light material and the surround part is made of a material with very high compliance.The “pistonic” diaphragm technology, normally only seen in much larger loudspeaker designs, gives the advantage of both a very low resonance frequency and superior bandwidth resulting in excellent sound reproduction properties.A typical free field measurement (as done for loudspeakers) with the receiver having no tuning filter on rear side (total open) clearly shows this very high bandwidth:

Performance
Free field measurement shows very high bandwidth.

Force factor

20201015_blx
The force factor is very symmetric ensuring low odd-order distortion

Cms

20201015_cmsx
Cms(x) has excellent linearity which contributes to vanishing low distortion even at extreme sound pressure levels
Klippel table
Klippel measurements show very high linear excursion .

Custom tuning

Ole Wolff can tune the drivers to match the customers preferred frequency response (position of 3kHz peak). One example of such tuning shown in the graphs below:
