Im looking on madisound for 4ohm tweeters for my install and I can across some of the vifa ring radiators. I was wondering if they can be used in CA applications or if I should just use a car tweeter

maybe a link to the tweets you're looking at might help... ****

Ring radiators have a rep for needing to be on-axis.

The XT25s?

Great tweet :)

The SS RR is quite nice, too :D

^This , if you can get them on axis enough they can sound great. :)

I've run the XT25's and the SPX17 tweets, both are ring radiators. When you get them on-axis they can sound VERY nice and have plenty of output. If you can't get them on-axis I'd look at other tweeters as it makes a HUGE diff in output/clarity.

Used them in my vehicle and a few others. Also use them in my house.

Do great on axis.

What's meant by on axis?

I feel stupid asking that.

x6 to the on axis part.

I have the Polk SR6500 comp set and I believe the tweeters are based of the XT25. On axis is a must, I had mine in the a-pillars firing directly accross (works good for many people, with other tweeters) but just didn't have it for me, imaging was good, but missing much of the top end information and not nearly as much output.

If you can get them on axis, then go for it, should be very happy.

Essentially on axis means that the speaker is aimed at the listeners ears, while off axis is just the opposite obviously.

Here my tweeter is mounted roughly on axis, while the mid down in the door is off axis

I am currently testing a set of Ring Radiators for a High End company that will be left nameless... I installed them directly on axis and sound very very very good... one of the smoothest tweeters I have ever listened to... output is still good when playing around (moving head to different angles) but you do notice a drop in higher fz as you move more off axis....Im actually sad that I have to send them back :(

So you came across them, or you were directed to them by someone who specifically recommended them to you for exactly this purpose? Did you forget already?

My SR tweeters are aimed ~10* off-axis relative to the listener. The upper frequencies sound slightly attenuated, compared to on-axis, but I wouldn't call it a night and day difference. It's certainly easy to modify with a PEQ, if one wishes. In my install, the tonal balance benefits from the effect (I'm guessing) due to reflections that tend to emphasize upper-mids/lower-treble.

I'm in the process of molding XT25s into my A-pillars. I tested them at various angles and completely off axis. On axis for ring radiators is the way to go. These tweeters sound great and extend pretty low for 1" tweeters. Great for 2-way systems. They are very detailed and the lower end could almost make it sound like a 3-way system with the output they provide...

Peerless HDS 6.5s (really more like 7s though). The ones that were on buyout at PE for like $32 each. I also have a pair of AA Poly's I picked up so we'll see. And I've taken a few pics along the way but not every step. Still waiting on my amp/processor...

I hope it was these ones pictured. PE had two different buyouts with HDS mids. I guess the ones pictured can be called HDS 'Nomex': http://i8.photobucket.com/albums/a11/mobster909/94CivicHatch/DSC03228.jpg

I listened to the XT25 both small and big versions. They sound great on axis, but thats it. I wouldnt use them in the car, You need long PLD's for them IMHO. If you are too close, the sweet spot is way to narrow, so every time you move your head in the car or adjust or seat it sounds completely different, Your top end will suffer the most. If you have a fairly deep dash or plan to use them in the kick go for it. I would absolutely never mount them in the sails or top of pillars. on the plus side you get less reflections, but the tradeoffs arent worth it enough to use.

he likes to bob his head up and down in the car..........to the music of course :D

I switched from xt25's to the alpine tweets and they sound even better IMO. I have experienced what MJ is talking about as mine are glassed in the sail panels, but I'm not that discerning of a listener. I mean you're in a car so wind noise, other vehicles, etc... all provide less then an ideal listening environment anyway...

Hmm no they aren't the same. Similar but they have "Nubert" on the backplate. The basket and cone look almost identical...
