Efficiency difference of 290-8K vs. 16K...?

[N.B.C.]

Does anyone know of any figures from reliable sources?

Thanks,

If Altec spec sheets qualify as a reliable source, see p. 5 of;

Like any typical HF driver offering a choice of diaphragms that differ only in voice coil impedance, the specified sensitivity is the same for either, given equivalent power dissipation, acoustic load, and measurement conditions.

I have to admit not understanding the motivation for your line of questions. That's not a requirement to post, but it might assist anyone helping you get to where you're trying to go. If it's nobody's business, that's cool too.

It's always nice when someone can refresh us with a little sensitivity training....(groan)

Hi bfish,

Thanks for your helpful information.

FYI, I'm simply trying to understand some of the technical differences between Altec drivers.

You're welcome, and as I said, it's cool. I'm kind of like an old dog that has to smell something over real good before he licks it.

Good analogy bfish.

A sensitive 'nose' is a good thing to have!

Sensitive 'ears' too!
