Hello all!

I have a pair of Celestion F15’s that I got for free. Hooked them up yesterday to find that both tweeters are blown (DMM resistance reads open circuit). Probably from an improper biamp setup. Celestion no longer has replacements available, so I’ll be looking at aftermarket options. I’ve never had to replace a blown tweeter, and I want to make sure I’m looking at suitable options.

Tweeter is 3/4” diameter. I’ve pulled one out, but no specs are listed on it.
Speaker specs:
Impedance: 8 ohms
Sensitivity: 89 db
Power handling: 10-90W
Crossover frequency: 2500hz

Woofer impedance is 6 ohms. Speakers are externally strapped in parallel. Do I have it right that a replacement 3/4” tweeter should be 6ohms, >10w, cut off frequency <2500hz?

Also looking for suggestions on vendors. I’ve looked at parts connection, and they have a few options. Definitely leaning towards “budget friendly” given these speakers weren’t very expensive to buy new.

Thanks in advance!!

my 2 ways and fullrange are published nominally 8 ohms yet they measure up at 6 ohms dc resistance.. Once option could be to take or send it to a speaker repair place. I did this for some midranges I had which were 40 years old and falling apart. They try to use original parts but can improvise when not available. There are youtube videos of people replacing voice coils but looks like finicky work. Probably for the very meticulous and patient.

I did see a listing on ebay for the f15 tweeter too. May or may not be same as yours. In HK though so it may be a gamle. see https://www.ebay.com.au/itm/One-New-Cel ... SwggRfsj0d
