My attempt at building the gr-research crossover upgrade for the Magnepan LRS plus speakers.

Improved version below replacing the aircore inductors with copper foil inductors. As you can plainly see in the photos I didn't do these but a friend I paid a $100 labor to do.

Nice tidy work.
Do you see a big difference between the two versions? Sound stage, precision, fast?

You still have quite a bit holding these back.

First of all, our resistors that we send out with the kit will sound better than the Path resistors. The Path resistors have steel endcaps as well (not good).

Secondly, using tube connectors will make quite a bit of difference, and easily more difference than going to the foil inductors.

Can you tell me the values ​​of the crossover components?

Thank you for the post and thank you to other responders.
I am myself going to be creating an external crossover implementation of the GR-Research modification of the Magnepan 0.7s.
I like the way the components are laid out in the new version: it makes it easier for me to follow the design for the high and low bandpass filter sections.
I am curious to know whether you plan to biwire the inputs to the crossover terminals or biamplify. (This seems to be implied by the dual inputs.)
Thank you so much for sharing your work.
