I have located your earlier thread regarding the Epos K3 crossover, to which I contributed.
Can some one please draw a me a xover
I attach the crossover circuit that you supplied in that earlier thread which, indeed, shows that the tweeter is fed via a 3.3uF capacitor.
If you think it will produce a superior result simply by slotting in a more expensive tweeter then it would help me to suggest a replacement if you tell me the following:
(a) How much does a replacement Epos tweeter cost?
(b) What is the maximum you wish to pay for a higher priced tweeter?
(c) What is the diameter of the face plate of the Epos tweeter (you will have to remove it from the enclosure to measure this).
(d) Are you prepared to alter the size of the mounting aperture in the enclosure to accommodate a different sized tweeter if found necessary?
