2'' dome fullrange

[adason]

That's what Lynn Olsen says

here's kinda
DSM50FFL - Solen Electronique Inc.

"midranges have no spider to keep them under control at high excursion, so domes mostly are low excursion designs. A long excursion is necessary for a 2" driver to be usable at low frequencies."

i am sick of this stupid lie
mid dome should be used from 800 or 900 Hz up, never with low frequencies
mid domes used properly have no issue and need no spider
measurements and listening test prove it
sick of this lie, sick!

Like you, Ed, I am sick and tired of being fed up
with being sick and tired
of being fed up with this nonsense!

What is your complaint Adason? The Olson quote says the dome SHOULDN’T be used at low
Frequencies and you say the same, no?

Aurasound whisper 2" dome full range at parts express. A favorite of Linkwitz. Hot glue a 6 inch long 1.5 inch pipe stuffed with fiberglass on the back and it is amazing. Aurasound NSW2-326-8AT Whisper 2" Extended Range Speaker Driver 8 Ohm

Why do you want a dome?

Because it's normally a sealed back driver

What do you mean by fullrange? You already stated it should go upto 20Khz. Should it also go down to 20Hz (probably not)? What's you use case?

I've said badly, I'd want a dome driver extended to 20 Khz, for sure not to 20 Hz, low end frequency doesn't matter, I apologise for my bad explanation

use something like a sb65 or an fr88 driver and make your own sealed back enclosure, there's many options for back if you don't want to use stuffed PVC tube, eg:

Interesting drivers thanks, but I would be oriented to TangBand W3-1364SA

because it seems to have a very good response, I've found a real test about its big brother W4-1320SI and it seems quite good so, if a family is a good family.. It's small enough to fit in a unused exponential old air port so I would be able to experiment with filling and maybe rear emission too. In the end, it's not excessively expensive.
But I've just found this Michael Chua test about TB W3-1364SA too, indeed it seems not to be so good working alone.
Have you ever experienced with TB W3-1364SA?

So your not looking for a dome, but for a sealed back driver..

But what IS the lowest frequency you need? Closing a normal driver will limit response down below or possibly generate a bump in the response, so the size of the back chamber might be important. Definitely do some quick simulation to find out.

Frequencies and you say the same, no?

I am not Lynn Olson. Here is the original quote:

Domes have a nasty dome resonance and it is difficult to bring it > 20 kHz for a 2" dome, without resorting to materials like diamond. Furthermore, dome tweeters and midranges have no spider to keep them under control at high excursion, so domes mostly are low excursion designs. A long excursion is necessary for a 2" driver to be usable at low frequencies.
