custom Crossover building service??

I agree, tweeters can fry pretty easily.

If you want to do it simply, try a capacitor in series with the tweeter. This will give all the protection you need. However, depending on the sensitivity of the tweeter as compared to your woofer, you may have to pad it down with a resistor, or two in an L Pad arrangement.

Hi

You can upgrade components in a crossover yourself. If confused about the circuit, make a drawing of what it is now and carefully note values of components. You can easily get a portable test instrument that measures inductance. Plan on spending about $140 for it.

You don't really have to draw a schematic of the crossover, though I'd recommend that you do. This is not rocket science and not impossible. Find a local tech to help you if you need to.

The reward for upgrading cheap caps and inductors with something better will be better sound. You will not hurt the design if you stick to the values in the existing crossover.

Consider the whole project as a learning experience.

George at North Creek Music will measure all the values of the parts for you if you send him the whole crossover. He will return it in a few days and give you a list of parts He uses at several price points than you can choose to upgrade some or all of the parts [ inductors , resistors and caps ]. I do not know the cost of this service so call George and talk to Him about your needs
