Knowles Fox speaker available

[jdcolombo]

I've never seen an 8x12mm speaker from Knowles, but I was told one was "in the works."  This from the same source that told me the Wildcat was replacing the Fox, so perhaps I'm now more inclined to give this rumor a chance.

The 8x12's that we hunted down were made by Star Micronics, not Knowles.

The replacement for the Fox apparently is real:

The first speaker listed in the above link is the Wildcat, 9mm x 16mm (the dimensions of the Fox), with an SPL rating of 94db.  Don't know when these will show up at retail places like DigiKey - they apparently are clearing their stock of Fox speakers first.

Still no 8mm x 12mm speaker from Knowles, however, and that's the size we really could use for smaller diesels.  I'm still wondering what kind of speaker will end up in the Atlas S-2, Intermountain SD40-2, Rapido GMD-1 and so forth.  Steamers are no problem; the Cobra or Donau would fit in nearly any tender, and the Grand would be the choice for larger steam tenders.

I don't speak the tech language very well, I noticed Seltech makes the Nith and the Zweigelt (wideband) that both measure 8x15 and have lower frequencies (better prime mover rumble???) would these be desirable alternatives?

Hi Rick.

I believe those two items are listed by Seltech as "receivers" - that is, they are intended for near-field (up against your ear) use, and simply don't have the sound output we need (look at the "air pumping" specification on the Seltech/Knowles web site, and you'll see what I mean).

Thanks John. I was looking at the low frequency listed and getting excited!

Now that just sounds weird Rick!
