Tang Band W1-1070SE - 1 inch transducer with 170 Hz Fs?

[arjscott]

I just noticed this on Parts Express. I'm not planning on trying to use it for anything, but I find it interesting that this 1 inch driver has an Fs of 170 Hz.

Has anyone tested one of these?

I can't find the datasheet for it. The only thing similar in appearance on the Tang Band website is this tweeter:

It's also 1 inch, but the Fs is 1300 Hz. Note the "Very wild dispersion angle" 😉

Looking at the surrounds, it certainly seems to have a very low Fs.

Hi,

To a rough approximation the lower the sensitivity, the lower Fs can be.

See hear for details of a 1" driver, Fs 225 Hz.

Looks very similar to the speaker in the old iMacs.

Hi!

I listened to this driver is a tiny vented plastic enclosure, it uses the same reverted dome than the TW mentioned. nothing to do with the old mac systeme. By the way it is not bad but nothing to wake me up from a sweet dream... in near field with several unit in a sort of line arrayy coul be good, it remains me something...
