Hello,

Are you also going to make a description of the housing for the speakers?
That would make it a complete project with your filter set you made now.

I wouldn't use passive cross over ever.
active cross over is the way to true audio.

By the way, ever thought about using wire wound resistors introducing extra inductance in to the crossover, you should go for cement ones.
Or am I wrong here?

Thanks! The box is already planned and I'll post it any time soon.

Indeed! Active crossovers are much more linear, but they require separate output stages for the high and low frequencies. You can have two approaches: an amplifier having those stages or an active speaker.

About the resistors, the ones I'm using have a cement filler. And the inductance is very, very small.

I guess then It's OK

hello there ,
can i use this circuit with the bass trrible and midi controller??
i jst have made the passive low pass bass trreble and midi circuit with adjustable gain of +-18db an i use tda7052 to amplify the power with 8 ohms speaker
can i use this circuit with that one???

If I understood your question, I think you will have no problem using those speakers with your amplifier. These are 8Ohm speakers.

 

I use tda7052 to amplify the power with 8 ohms speaker

If the supply is 6V then the output at clipping into 8 ohms is only 0.96W. A cheap clock radio has more power.

Your tone controls have a max boost of about 80 times the power so unboosted frequencies have a max power of only 0.012W.

Indeed! Those speakers will sustain up to 50W nominal power, which is far greater than the power of 1W that a TDA7052 can provide.

I'm afraid we are going off-topic here. I don't see any point or relation with the actual project being discussed here.

 

Someone messed this up big time. This thread should be called "Project: "Cygnus" 2-way speakers". This is Cygnus, not Lynx.

 

Hello,

I changed the title for you.
