Transducer Lab Tweeters ?

[gowa]

Has anyone used these tweeters?
If so, what are your impressions? (Good and bad)

Thanks

Re: Transducer Lab Tweeters ?

I've used the N26C-A and it is excellent. Dan Neubecker used it in his Echelon speaker too.

Solen and Meniscus carry them I believe.

They are the nicest dome tweeter I've ever heard. Massive motors, huge rear chambers, very low resonance frequency, and smooth extended response. The flange is a bit of a stumbling block as they are very large, but both Dan and I put them behind a waveguide so it became a non issue.

The ceramic dome is incredibly thin and extremely fragile. I'm sure that has a lot to do with the sound, being very light weight coupled to a massive motor.

This guy makes waveguides for them. davepellegrene ;)

Pete,
I would use them without a guide and would hope to cross them at 1.6k. How do you think they would hold up?

Should be no problem at 1600Hz. I think Meniscus even sells little screens to protect the domes from prying fingers.

I'd still recommend a guide though. It only improves their performance and look.

I need to offer a small correction. We used the N26C-G.

I'm looking forward to trying out the N26C-R or N26C-S. Eugen at T-labs says they are a definite step up from the existing versions.

I saw three new ones at the InDIYana event this year. Wolf had them. The domes where made of different materials . Beryllium, Kevlar and carbon fiber? One also had a round faceplate so maybe that will be an option.

They can cross fairly low.
Didn't see fairies flying out of the loudspeaker while listening to them but they sounded fine.
Response I got from the pair I had wasn't quite as flat as manufacturers.
If you absolutely must cross that low, it's one of the better choices. Myself, I'd probably opt for a 3-way and put a midrange there instead of pulling the tweeter to it's limit.

Re: Transducer Lab Tweeters ?

I have a pair on-loan from a forum member here. We can't decide what to pair them with. Any suggestions?

Paul, I have been thinking about drivers, we will come up with something.

Re: Transducer Lab Tweeters ?

I just finished a custom design for siggma. Fairly straightfoward to work with - 3rd order HPF @2.8kHz. It rolled off in the top octave similar to a soft dome, then shows a large hi-Q spike at 30kHz (not a bad thing, IMO).

I can't wait to ship these back to Tom, because if I look at the white dome too long, I'm afraid it will crack.

Re: Transducer Lab Tweeters ?

Fantastic tweeters, IMO. Assuming your talking 2 or 2.5way and not 3way, perhaps a pair of these, possibly TMM 2.5way.

Though sealed might be a better match from a transient response perspective, so one of these sealed might make for a nive 2way, or even a pair in a 2.5way if you don't mind a larger box.

Also, if you were to put the tweeter in a nice Pellegrene elliptical waveguide, cross where the directivity is a good match, even better.

Re: Transducer Lab Tweeters ?

He used an Aurum Cantus 15cm mid in a small sealed box.

He wants a dual-15cm mid center channel next. The two square frame mids will be right next to each other, with the rectangular TL tweeter above those.

I only gave the TM pair a listen on a movie, plus some sitcom TV, just to be sure that there was nothing out of sorts.

Disclaimer: I am not the guy to ask for tweeter recommendations, because I think people obsess too much over tweeter choices, and not enough over midwoofer choices.

Philip, if you do not mind, what drivers did you use and what did you think of the design over all ?

thanks craig
