Cone Tweeters

[Jay1]

I guess the proper term nowadays is full range driver... Does anyone have thoughts or recent experiences with foregoing a traditional tweeter, but still having a proper speaker design (not FAST). I've already decided to press ahead with a build using the Vifa TC7 as a tweeter, which is a pretty impressive little 2" cone tweeter for only $10



I has half expecting this little guy to be pretty flimsy, but the rolled steel frame is actually very strong, and still thin enough to surface mount.

I understand off axis will not be as good as a 1" dome, but whether or not that is a negative is highly debatable...

Well alright I guess im the only one who thinks this is a cool idea. This is my favorite thing about DIY, if I like an idea I can just make it happen

Re: Cone Tweeters

I do like the idea and have been mulling something similiar. Maybe repurposing a pair of Realistic Nova 6s, 8" woof and similiar mid/tweet. The Nova 6s actually used a setup that was a bit akin to this, the tweet was open back and sat in its own plastic subenclosure. Crossed at around 3k though

Re: Cone Tweeters

This little TC7 should be able yo do lr2 @1khz or lr4 @500hz with pretty good output before xmax. Im guessing the thermal rating is for full range use.

Re: Cone Tweeters

Looks like an interesting driver. Might have to pick up a couple of those with my next order.


bungelow_ed used the 2" Tymphany buyout as a tweeter in his design linked below.

Re: Cone Tweeters

I used a 2" Tang Band full range for a mid/tweet in a 2 way with a Peerless/Carver 4 ohm 5" whose mids never sounded great. It definitely helped the mids and the highs were okay. Not as nice as even the Dayton 3/4" Neos that were pretty reasonable at the time, but I thought an overall improvement.

Yes, and it has distortion performance similar to a $50 tweeter, with the obvious low frequency advantage




Thanks for the link!

Re: Cone Tweeters

Are those your own measurements? If so, I see you cut them off at 10K. I'm curious how the response is from 10K to 20K.

Zaphs measurements from his blog

Re: Cone Tweeters

Henry Kloss used cone tweeters in his Ensemble speakers to very good effect.

I guess we probably all have built or thought about building what you are suggesting here: to mate a cone FR driver, wich is capable of extending low, with a (sub) woofer which is not capable of reaching high enough to mate with a standard tweeter.

This works reasonably well with a relatively efficient FR driver. However with the driver you suggested, with an SPL of 82.4 dB, this will only work well with a woofer with low efficiency, such as a TB W5-1138 or TB W6-1139.

The one linked would work a little better at a decent price. There are other ones, a little more efficient, probably a little more expensive as well.

+1 just finshed a build with the the FE85. I used with third order at 1,200 hz with no shaping at the top end. Sounds decent. These will be at MWAF if the web site ever gets up.

That's HD measurements, only goes to 10kHz

Re: Cone Tweeters

There are a few high-end manufacturers that have actually investigated cone tweeters for their current products. WLM Loudspeakers of Germany used a Visaton cone tweeter in their Stella and La Scala models for high sensitivity, and Audio Physic has a proprietary new(ish) tweeter that uses a somewhat cone-shaped aluminum diaphragm. The newer Horning loudspeakers use a custom spiderless cone tweeter, which sounded very good when I heard it at last year's RMAF.

Cone tweeters do have the benefit of a larger radiating area than most soft domes, where the outer diameter of a dome is the same as the outer diameter of the voice coil. That being said, unless you're really pursuing a high-efficiency and high-dynamics design, dome tweeters get you most of the way there. If you want extra dynamic capability, use one of the larger dome tweeters available, like the 28mm designs from Dayton, Usher, Scan Speak, and Morel, or the even larger domes from Scan Speak, Wavecor, or Seas, in sizes up to 1-1/2" in diameter.

Cool. I am curious to see what you came up with.
