While await hearing from Rob at Thiel service I started thinking and researching , HiFi Shock has some great hi def pictures of the crossovers, you can see the difference in the 2.4se and the 2.7.
I also looked at the 3.7s , I thought that with them being the cost is no object that would look like the 2.4se but they look like they used the same caps as in the 2.7s .
Anyway if they can't be done by Rob at Thiel then I will try to find the capacitor manufacture that they used on the 2.4se and do it myself,
though this my have to wait until next year when I retire.
