Lydrommet has only the whole repair set with cone, as you say.
A bit costy 2900.- nok/ 480 USD to one element. This is 1.5 x the price i gave for one 2245!

Lydrommet actually had a new 2245H! approx 7600.- nok/ 1300 USD. But does JBL still make this element?
The recone set was also genuine JBL they said. Is it also really availeable from JBL these days?
