=> In 65 liters, it just doesn't breathe healthily, and pressure mecanical problem.

I had never used hornresp for/like that before, but should be promising. Can someone confirm my explanation ? (it seems me counter intuitive, related to volume displaced should be equal for same acoustical power...?)
Hi papasteack,

What input parameter values are you using?

I get a different result to you for the two JL Audio 10W7-3 drivers connected in series.

Kind regards,

David
