Modifying Crossovers

@vair68robert I toyed with the idea of having my crossover box made by a friend that does woodwork.  Since there are no external controls it isn't hard to make.

Seems making boxes and selling them is a nitch that someone should fill.  I don't enjoy woodwork enough and don't need a new business but it would not be hard to mass produce them.  Maybe I'll find a young guy and back him financially.

My plan was to replace components  on the boards and leave them internal.  I was going to have to add a 3rd board for the large inductor.  In fact I made one of them but it was going to be real tight.  Here is one of the boards (since disassembled):

Beautiful work.  I like your choice of capacitors.  Mundorf, at least to my budget, are my favorites.  I've used quite a few of the EVO Oil caps in speaker rebuilds, and have always liked their sound.  I'm using a mix of Supreme EVO Oils and ClarityCap CSA's, on a current project.  Hope to get it completed soon.

Also, I've never done recaps, on both vintage or new speakers, where the recap didn't improve the sound.  I've only done like for like recaps.  Never anything to mod or change from stock values, and never been disappointed.  And I do A/B the stock speaker, to a recapped speaker, for comparison.  I even volunteer family members, for an extra set of test ears, and they hear positive differences between the two.  So, I don't shy away from tearing into a speaker, if the base design is worthy of the upgrade?  Part of the fun.

Interesting discussion.  I am pondering updating the crossover components on my IRS Beta. They are original except that I have "re glued" some of the components that fell off.  Odd that they used what seems to be glue gun adhesive and then hung components instead of placing them on the bottom of the crossover enclosure.

In my case, there is Bayer in Germany that developed a modern crossover for the speakers.  I wonder how they sound.......

If you have room move the crossovers as far away from the  woofer as possible .

thanks!
