difference bewteen ring radiator and soft dome vifa
tweeters in terms of suitability and sound character.

thanks.

It would probably help if you had specified the model number, as Vifa have 3 versions of the ring radiator type and also quite a number of soft domes.

The 3 ring radiators have variances in their characteristics thought 2 of them are similar, namely XT25 and XT25neo, the other model being XT19

From my lil' silly experience with Alpine-Scans D2904-6000 and Alpine-Scanspeak Ring radiator Tw.

F13M-Tw - very easy to accept the sound, although I do find the stage is kinda low, position is very crucial on the height of the Tw and it needs a lot of good juice to push it. Not bright, not mellow.

Z15M-Tw - BIG! 1st impression was the sheer size of it compare to the F13M Tw. Untune, I find it overly laid back and slow to certain extent, tune it right, it creates a lovely rainbow of vocal, if you would prefer. Depth is good and it goes a tad lower than the Vifa. There's a certain airy about this Tw that I like a lot, which is missing from the F13M.

It boils down to preference. Both the Alpine-V/S speakers are good to my dumb ears.

foo, sorry to correct you, but the both Alpine variants of the tweeters you mentioned are actually from Scanspeak, only that the midrange and midbass drivers of the earlier Pre F#1 flagship are made by Vifa and the F#1 is a full Scanspeak set.

built, as for the D27 vs the XT25, i can't really say much considering i didn't had any experience with the D27(or the currently easily available D19 variant), but for the XT19 and the XT25 variant, i would say they have a very good dispersion, maybe due to the design they have(with the protruding "nipple"), sounded a bit forward for my liking with aimed on-axis, but then again, they don't sound really good off-axis, very directional type of tweeter so u need to get the aiming right, liking it or not actually depends on the type of music u usually listen to i suppose. The closest retail market variant of the XT19 would be the Alpine SPX-177R tweeter and the XT25 being in the Polk SR6500 set. I personally prefer the XT19 over the XT25 for it's sound, doesn't necessarily mean a bigger dome produces a better sound i suppose.
