[R-390] Tellabs Speakers

[Barry]

The local old-timey electronics store is going out of business.  I visited 
this morning (their last official day) and browsed the aisles.  I didn't 
find anything I couldn't live without (even at 50% off everything), but I 
did come across a couple of Tellabs speakers and I wondered if anyone out 
there might be interested in them.

These are some kind of communications speaker made for the 
telecommunications industry and are housed in a very nice heavy all-aluminum 
housing with brushed aluminum front and trim and a gray gloss "shell" for a 
back.  All in all, a very quality-looking speaker (although I didn't hook 
them up and see what they sounded like).

I think they have a 4" speaker with an on/off/volumn control on the front 
and from what I could tell, they had an internal amplifier.  There is a 
little red LED on the front assumably to indicate when the power is on. 
They also come with a data/instruction sheet with wiring diagram.  If I 
recall, they needed some 30 to 50VDC for a power source and, again IIRC, 
about 900ma (seemed like a lot of current draw to me).

At any rate, the thing that made these interesting is that they apparently 
have several impedences for input, 600-ohms being one of them.  Don't qoute 
me on this, but I think they also had 8-ohms and maybe something higher than 
600-ohms as well.

All-in-all, these appeared to be quite nice.  If I still had some mil-radios 
with 600-ohm output, I would have gotten at least one of them but passed. 
If anyone thinks they might be interested in these (in a "man I saw one of 
those one time and would kill to have one now", etc.), I think I can still 
get them even the store is officially closed (and they didn't sell them).

Just wanted to let the group know in case they are uber-cool and I just 
didn't realize it.
