Audax?

The only thing I can think of that comes close, is the Audax models. One has a rising response that *might* work for you but I have not tested them. Only looked at the datasheets. I think troels has used an Audax in one of his high efficiency builds. You should be able to find a source for this in the States.
 
Hi M,

Please consider this note a "Monty Phython" Now for something completely different.

When I studied controlled directivity and hearing_error_sensitivity my experiments with soft dome tweeters gave the best results when I researched dome tweeters like the SB29RCDN (*jay1111 *Linkwitz) with steep slopes ~1400Hz to medium diameter midbass speakers(phase plugs helps). The small size and low Fs of the SB29RCDN made it a "standout" in LOW Fs, Xmax, 94db/watt EFFICIENCY, minimal lobing, and SMOOTH with GOOD DETAIL.. not great detail. .. not magic.. just invisible. $60

The 66000 dome always sounded the best in terms of smooth, detail and accuracy. $250

BIG PICTURE: I have never been able to get controlled directivity, or an invisible Xover, or limited lobing, with a tweeter Xover above ~1600 Hz. (13500in_per_sec / 1600_hz / 2x_to_4x_polar == lobing)


Happy to extend post if any interest in Something Completely Different.

WIKI:
Vocal_range is the measure of the breadth of pitches that a human voice can phonate. The most common application of the term "vocal range" is within the context of singing, where it is used as one of the major defining characteristics for classifying singing voices into groups known as voice types.

The following are the general vocal ranges associated with each voice type using scientific pitch notation where middle C=C4. Some singers within these voice types may be able to sing somewhat higher or lower:

Soprano: C4 – C6
Mezzo-soprano: A3 – A5
Contralto: F3 – F5
Tenor: C3 – C5
Baritone: F2 – F4
Bass: E2 – E4

In terms of frequency, human voices are roughly in the range of 80 Hz to 1100 Hz (that is, E2 to C6) for normal male and female voices together.

Fundamental Speech frequency
The voiced speech of a typical adult male will have a fundamental frequency from 85 to 180 Hz, and that of a typical adult female from 165 to 255 Hz.

Neodimium had made the prices rising...
Sica with ferrofluid with small rectangular faceplate, 1,1" with ferrofluid
95,8 dB sensitivity>>>>Model LP 53X58.28/N20>>>Sica code: Z008985

Same brand, double cost, no ferrofluid, alluminium faceplate, a much lower Fs (600 Hz), the top! ( haven't heard it...I went with the 16 € basic model :eek:)

LP 90.28 / N92 >>Code Z009160............94.4 dB/W/m

End of commercial....enjoy:shhh:

I do not doubt that the SB29RCDN is a good tweeter but it does not produce 94dB/1W, it produces 94dB at 2.83V. Being a 4Ohm unit AFAIK that is 2W, consequently at 1W it does 91dB.
 
Gentlemen,

thank you again very much for the additional suggestions.

Kindest regards,

M

Gentlemen? Are "ladies" not allowed to contribute? Am I in a time warp? Let's go into the drawing room and smoke cigars with our brandy and discuss this while the women babble about insignificant matters.

Right on dude! Let's bring back the 19th century!
