The N version just barely meets my spec'd needs... it apparently flattens the upper section of the response... IF you believe the published specs. Apparently there is some internal difference in the rear chamber due to the Neodymium magnets that may be responsible for that. The horn shape has some degree of promise... not sure what these cost...
The HF dispersion angle won't meet the 60 degrees... all tweets like this beam.

Same p-audio tweet sold by monacor germany in the stage line range.
And it cost 31euro over here. About 41dollar.

That is 5dB and very easy to correct with 1 resistor and 1 capacitor. You can't hear frequencies above 15kHz

Yeah, I was going to say I don't worry too much about anything above 15kHz, as I definitely can't hear it. I doubt my wife can either.. In any event I spends me limited money where I can hear it..
I'm pragmatic and old..

Are you sure about that??

PS. ...and with the correction the reference sensitivity drops significantly... I want dogs, children and young people to have the proper listening experience if at all possible... also there is the issue of sum + difference coming out in the audible band...
Here some more Italian drivers.

My supertweeters kick in at 15k and I hear them quite easily.
I'm 46.
You're very fortunate..
I'm in my very early 50s and I don't hear anything approaching 15kHz any more, nor do most of my friends - some much younger and some older. I've had my hearing professionally checked as have most of them. My threshold drops pretty quickly beyond about 12kHz, and 13kHz - 14kHz is about the limit of what I can hear under the best of circumstances.
I have friends in my age range who can't hear above 8kHz, again tested.
Too many loud concerts & discos back in the day, and roller rinks (probably the worst..)
Age and perhaps to a lesser extent heredity play a role as well.The U.S. Navy is having real problems these days finding good candidates for sonar operators as most youth have seriously damaged their hearing by the time they are of enlistment age.
Yes, probably first order filter. you will even hear 3kHz.

All my xover slopes are active 24dB L-R. The supertweeter is additionally protected by a passive 3rd order hi pass at about 7-8k.
Ok, has anyone TESTED or listened to one of the bullet "super tweeters" like the Pyle PDBT-35, also offered by Cadence CLVT-60, Audiopipe and an number of other resellers and importers. (Peavey too?)
There appear to be a few versions in 4 ohm and 8 ohm, ferrofluid and not, also higher claimed sensitivity (~108) and lower (~98), higher and lower power handling. All seem to be China sourced. (would like to know which factory makes 'em).
If anyone has a bonafide curve and waterfall for these I'm interested in seeing it.
Parts Express sells the either the Pyle or the Peavey, can't recall now.
Also there is a Visaton unit at higher price that is somewhat similar in design, the published curve for it is not bad... Visaton - Lautsprecher und Zubehör, Loudspeakers and Accessories
I'm very curious as I am looking for something to augment a very nice horn above ~10khz... (not an easy task in reality). Trying to gauge if these inexpensive units have enough merit to warrant dorking with the obviously flawed horn flare to "gild the lily" or make the "silk purse from the sow's ear"...
Yes, I have actually gone ahead and purchased some to check out - but I'm interested in what others have found and measured...

Hi Bear,
The Visaton that you mention above is very much like the one that Lew Hardy used in his Vivaldi Audio horns and they certainly sounded great! He used a modified Academy cabinet with two Lowther's per cabinet. They were very smooth sounding, one of the best speakers I've heard. Dan Wiggins did the crossover.
Best Regards,

That Monocor MHD-540 looks a lot like the Fane bullets I have. All JBL clones, I suppose.
Maybe they are JBL. Monacor sells stuff produced by others.
Like P-audio,TVM-acoustics,Tangband,celestion as it has a good price performance they sell it as their own.
