All you need is the H290C waveguides and to make a small change to your crossover. We remove capacitor C1 and add resistor Rs. I'd suggest buying the unstuff PCB we make now to clean things up, not because it's better electrically but because it is a cleaner install than the cable assembly that has R1/R2. The new PCB has locations for those components on it.

The Delta 12LF and PSD2002 drivers you have are still current entry-level offerings, and they sound good. The premium upgrade drivers are the Definimax 4012 midwoofer and the DE250 compression driver, which provide smoother response and reduced distortion.
