My 19's are clones, with 416Z woofers and 9028A horn drivers. Presently they are tri-amped with the horn/woofer x-over at 24 db/oct 1200 hz. Sounds really nice.

But I have a curiosity as to what the originals sounded like. I'd like to try the passive crossovers. So I have an 8ohm horn driver and a 16-ohm low frequency speaker.

Can I build the original x/o and hang a 16 ohm resistor across the woofers? Swap the woofers for 8 ohm versions? Build the Zilch version and adjust for the higher woofer impedance?

Any input appreciated.

thanks
