resistence is futile

At least for my non-electrical smart brain. Recently purchased a replacement tweeter for an old JBL cabinet....turns out to be 8 ohm, while the woofer and speakers in the other cabinet are 16 ohm.....any way I can use this new tweeter?

Thank you very much for helping!

need to adjust the crossover. post the details @ and you will get the help you need.

Which JBL? you may be able to purchase the correct driver on ebay, as there are scores of JBL vintage drivers posted all the time, at rather inflated prices I might add ($400 for a pair of the infamous glass tweeters used in the L-300's for example)
The tweeters are LE 20's.
