Jim said he wanted to refine the 2.4 mechanical-crossover tweeter with the 3.7-type radial wave diaphragm, for use in the 7.3 and then also apply it to a 2.5. Tons of potential goodness there - no crossover components is cleaner than great crossover components.

A CS 2.5 ? Yes! Tons of potential goodness there. I would be the 1st buyer in-line.

Happy Listening!

2nd Note- my space cannot accommodate a CS 3.7 nor 7.3 loudspeaker to due proper justice.

Happy Listening!

If a CS 7.3 cannot come to fruition how about visiting a CS 7.2 crossover to upgrade and do external crossovers with all new internal wiring? 

duramax 747 - Yes, indeed. The 7.2 wasn't on my radar, being a relatively new product with no service issues. But not that I'm getting a pair it becomes more a part of my working stable. The new wire (nearing finalization) and upgraded components, layout and fluid-flow wavelaunch technologies will all apply. My redevelopment work is quite universal in that the new solutions and techniques apply to all products across the board.

This week I am deriving a crossover schematic from the layout drawing. I am pleased to see no electrolytic caps on the drawing - I'll verify from my actual speakers.

Note that the 7.2 crossover is on the  cabinet bottom (my favorite place) behind the passive radiator and quite distant from the woofer and upper drivers. So in stock form its EMF exposure is minimized. The 7.2 is eminently upgradable in due time.
