Hello again,
After reading so much I've made myself cross-eyed, I've come to the conclusion that nothing I do with my xover or new tweeters is going to fix the biggest problem with my dipoles - ie the vifas.
Looking at local sources has thrown up just one real possibility for a sub-$100 replacement: the Seas CA21RE.
I've read on here (and noticed on the published curves) that the Seas L-series 8-inchers tend to die away even lower than 1kHz and that the latest CA22RNX has an obvious mode at 600Hz which doesn't bode well.
Now I'm looking at the plot for the CA21RE and I was wondering if someone more experienced can tell me whether it looks suitable:
I like the sound of its lower moving mass (22g vs ~30 for my Vifas) & higher Qts (0.48 vs 0.27), but am a bit concerned by its Xmax deficit (3mm vs 6).
What say ye?
TIA,

PS Sorry if this has been discussed, I tried every search I could think of for this particular driver.
