Frequency Filter Full range loudspeaker

[vvxuan]

Hello everybody
I'm Vietnamese
I used some driver Full range, as Siemens klangfilm 22C, Philips 9710M01, Nirvana 10' Al, etc...
But, sound from mid to mid high is very much.
I was build a schematic parallel notch circuit.

I can adjust to fix mid sound with bass and tweeter

You see, mid sound change when I used filter.

When I don't user Filter

When I turn 1/4 volume (about 8Ohm)

And when I turn to 33ohm

And overlay

Seems like you need a shelving circuit. Usually a series coil in parallel with a resistor should do the trick. You can use Jeff Bagby's Passive Crossover Designer to simulate and find the right values for the shelving circuit.
