why not 3rd LPF order? (BD-Design)

Hi Chris,

Thanks for the link.

I am working with this Second Order Low Pass filter but I overlap the
'reference' BD15s with Hedlunds so figures are not really relevant to
you.

I've been curious why Bert and others don't use 3rd order LPF which produces in-phase operation.
I'm about to add a simple R/C, 4.7k/15n by this the simulation shows all most the same curve adding only the 3rd order.
