My two-way active speakers use a Kef B200 SP1014 mid-bass and a Seas H254 tweeter crossing over around 1500Hz. The tweeters have a free-air resonance of 1,400Hz and a recommended operating range of 3k-25kHz, however they use ferrofluid which allows higher power at the lower crossover frequency.
The ferrofluid appears to be drying out as they have developed an 8-dB dip at 10+kHz, so I'm looking for a replacement and given the improvements in driver technology over the years, this seems like an opportunity to upgrade to a driver which can handle the low crossover frequency better and perhaps perform better all round.
According to Falcon Acoustics, who've been very helpful, the Seas H0831-06 is a drop-in replacement, however it has a free-air resonance of 1,200Hz and a recommended operating range of 2-25kHz.
I've looked at a few ranges of tweeters, and found quite a few which may work well, but manufacturers have multiple grades and with their technical data it isn't clear to me whether the improvements with their more expensive offerings are significant.
I'd appreciate suggestions, preferably based on measurements and experience, of good-performing units.
TIA
