Hello,

Could someone be so kind and help me by advising diamensions of BR port for LF18N405 speaker in ESW1018/MT18 cabinet? Important for me is outside diamensions 80x60x60, if I compare this plans there are difference but I don't know how much impact they have, which will be better for my driver? Or what diamensions would be best?

The ESW is not really a BR (look at the impedance graph on the event series pdf).

I think you are ok with the original ESW design. Standard it used the L18S800/801. They are quite close spec wise. The 800 will have a bit higher sensitivity (mostly higher up) but the 405 has more linear excursion.
