Then the mid/woofer (Faital Pro 3FE22; 75mm cone; 100Hz-20,000Hz; 20W nominal) could be faulty.

Can you test it on its own from another amplifier, radio etc.?

I don't have others amp for doing this. And to be honest I don't know how to test a speaker exept by listening to it. But according to its frequency response I don't think it is the speaker's fault.faital pro.JPG

Can I make a mono amp by soldering the two output of a stereo one together ? If so, is the power of the mono equal the sum of the two power output of the stereo ?

I refer you back to post #47.

P.S. I have no idea why you would want to do this, as it will not solve your present problem, but only introduce added, unnecessary complication!

I'm only asking you to listen to it.

However, in order to test it, you would have to disconnect the Faital driver from the crossover board then connect it to an amplifier other than your class D module.

Connecting the driver to the headphone output from a radio, mp3 player or mobile phone would serve as a test.

I'm afraid I can offer no more advice - either the Faital driver or the class D module could be to blame for your problem.

Thank you.

Without actually being there to listen to your problem, it is very difficult to understand (a) what the problem is, and, (b) what the solution might be.

If you have a friend with an amplifier, use this to test your complete loudspeaker system (the subwoofer, woofer and tweeter combination).

If the speaker tests OK, then try a different Class D amp module and/or power supply.

One other possibility. Could the 'resonance' effect in the midrange be caused by your music source (MP3 player etc.)? Try another source to find out.

Or maybe you just have to accept that the effect happens, but only with certain music tracks!

Best wishes, I hope you can find a solution.
