First off with all my experience in hand you are going in the right direction minus one thing. If your using 100% the original Klipsch crossover schematic theme on the tweeter than you will get into trouble, meaning they normally only use a single resistor to cut db right at the input of the positive lead going into the crossover section.
What first needs to happen is dump the resistor on the front of the crossover all together. You are restricting the pure capability of the far superior Caps and inductors your loading behind it.
You need to put an "L Pad" at the output of the crossover right before the tweeter driver itself. The results far more natural and wider sound as your allowing the full crossover to saturate with power from the amp itself feeding it, and at the same time not reaping havoc on the impedance the amp is feeding back.
Fact is I had a klipsch horn that was running hot in the first place. It used a single 2 ohm resistor cutting the whole signal right at the input terminal the amp first sees feeding your crossover, which being hooked in parallel with the tweeter, Mid, and Woofer network actually adjusts the signal to all your crossover inputs in my opinion from listening!
If your using Duelund Resistors I will say this vs. Mundorf or Mills I have used they are slightly more "Transparent" in audiophile terms, and "Bright" in Layman terms.
For example my 2 ohm resistor in the original design was cutting lets say 2 to 3 db. However I found with a Duelund I needed to cut 4.5 to 5 db as its just more out of the signal not damping it as much from my experience, this can be a gift or a careful what you ask for result.
Online you will find a debate about the L pad and its placement that should be AFTER the crossover on any design, not BEFORE the crossover as most generic crossovers do in fact have. Huge difference as now you are loading those expensive caps and high current is really feeding the whole system this way.
Also online you will find several L pad calculators that are easy to use, you plug in the 8 ohm impedance you want, and tell it how much DB you want to cut. It will spit out the Parallel resistor and Series resistor Values that should be used. This is the same formula regardless what speaker you use power cutting is the same on all designs, not saying the same amount of power cutting but the same way to cut it with any L pad vs. just a single series resistor.
Trust me it is FAR superior. I was actually cutting with a single 10 ohm vs. the 2 ohm originally, what a mistake it was cutting the bass, tweeter everything across the board as it was raising the impedance too much at the amp tap. Put the L pad after the crossover and with the correct value and the amp will see it as transparent totally making the speaker balance out to its optimum, and you get full use of those expensive crossover components.
