I sure would like to see a side by side of the two crossovers, (old and new)THAT would tell me a lot.. Any chance you could post a couple of pic in your "details"? If it's lost the highs its a resistor of some type in the HF path.
I'd look where it was hooked to the Highs and see if an inductor or resistor value was added and its GREATER than the original, or as simple as getting the decimal point in the wrong place.
If the HF driver wire was hooked up at the beginning of the HF circuit VS the end of the circuit? That would cause the bass to still be going through the HF side.
A series XO always coming off the + side and on to the next frequency is pretty easy to see the resistance in the path.
Here is the issue I could see in my minds eye. A resistor at the driver that is NOT on the XO. BUT because the resistor was left on or in the HF path the ADDED (but normal) resistor on the new XO doubled the resistance and of course cut the HF signal from getting through.
I would look to see if there is a component that you didn't see or were even looking for. Look at the HF driver terminals and make sure there is nothing in the path and if any type of wiring is going to the Negative side of the driver wire all the way to the new XO. Just a thought..
If I was the builder though, I would have wondered WHY I had to add the greater value from the old? The light bulb should have gone off.. WHY?
And know a Tannoy XO is not going to be that far off.. IF AT ALL!!
Yet the only customer complaint is "It's Old". NOT broke.. old...
All I got for no cost. I woke up at 3:30 thinking about that.. And of course it's time to feed the rabbit.. Junior. :-)
Regards
