If you want to take it to another level......here are some suggestions:
1. Hardwire everything......no spades on your speaker wires.....hardwire your speaker wire right to the xover parts. Remove the connectors from the xover to the panels. Hardwire the wire to the woofer right to the voice coil wire.......where it is attached to the tab on the speaker.
2. Make an external xover and mount it either behind the speaker (damped and isolated from floor or isolated from the woofer box on top of the woofer box). Use cryoed 12 gauge wax coils from Jantzen and make sure you go into the inside of the coil and out the outside. Hardwire all the xover parts together. Use the best caps and resistors you can afford. Check out this custom xover (bottom of page) I made for some Apogee Duetta speakers a couple of years ago:

3. Put felt all around the front of the tweeter.....overlapping a hair over the inside edge that the tweeter sees. Way more focused and pure.
Please share with everyone the xover for the speaker.....so we can all do mods and help each other. You cannot hurt ET by doing this. These are custom drivers.....he cannot lose anything by you sharing the xover schematic. He can only win....if people tell him what sounds better that what he uses......he can then build a better speaker and we won't have to mod it. Its a win-win.
