Help with V-Cap ODAM directionality in crossover

How did your upgrade turn out? Most interested.  Yes, the caps will take some. 120-200 hours to be 90% burned in. They open up a lot in just 30 hours. 

I assumed you were just using the Odams on the tweeter board. If using them on the woofer board, then that cap is most likely in parallel with the woofer driver output leads. This cap position is far less important than a series cap, but still can offer sonic advantages when upgraded. I really don’t think you need to be concerned about direction in this position. Really won’t hear it in my opinion.

Some argue you won’t really hear a sonic difference with series caps (direction) in a crossover.  I have not tested both directions while doing an upgrade so I don’t  know for sure. I just figure why not install them as the manufacturer states as that is certainly not wrong! 

We cannot see under the board to see how it is wired. Nobody can tell you without seeing the circuit and the circuit is not visible on the top of the board.

Simply study the circuit under the board or even better use your multimeter checking for continuity. Just follow the circuit from the positive driver output (tweeter) back using you multimeter checking for continuity. The cap will be in series with the tweeter and may well be the very last part before the positive output wire to the tweeter. Just check for continuity from each side of the tweeter cap to the positive tweeter lead output. Once you determine continuity that end should be the “V” end on the Odam cap and the the other end is the outer foil. This is most likely that top left cap located to the left of the output.

The other cap below it is most likely in series with the cap above it. Again, use your eyes and/or multimeter to verify. It should be placed on the board in the same exact manner as the first cap.

Just study the circuit from under the board and/or use your multimeter continuity setting.

Proper heat dissipation by allowing air flow all around resistors. Perhaps a tad too high off the board, but overall a great idea. Need to lift resistors off the board and do not use hot glue anywhere near resistors! 

Depending on where the boards are mounted in the speaker other measures can be used to help tame vibration. 

Nice job on your upgrade.  Happy all sounds great to you.  Enjoy!
