How to determine crossover frequency?

Hi,

Thanks to members who replied to my previous post:

This one is a follow up.

Is there an easy way to determine crossover frequency without knowing driver parameters? I have speaker cabinets with built in XO and I would like to get matching pair of tweeter/woofer. The problem is, that the XO is permanently glued into the cabinet and some resistors and capacitors are facing down so I cannot read the specs. This prevents me from reverse-engineering XO by studying its components.

Please remember that I am a complete noob in DIY audio stuff 🙂

Thank you,
Alex

you could get a ball park amount by unplugging a driver at a time and doing signal sweeps to figure out where each starts to roll off.

noodle_snacks: The problem is, that all I have is box with XO. No drivers. I know that the tweaters were Seas 6 Ohm model H310 but they are not available anymore.

Any other suggestions?

Thanks,
Alex
