Product Brand & Model:
Infinity EMIT-R Tweeters (Pair)


Condition of all items:
Used. 8/10. Front looks great. Rear shows signs of mounting.


Total Price: :
$120


Shipping Terms: :

Pictures: - Will add later.


Additional info:
Will not sell individually. Of all tweeters I've heard in-home and in-car, these are by far my favorite. Not harsh but not mellow... a perfect blend. And they're extremely efficient, solidly built, and great looking.

These are highly regarded and originally used in Infinity Reference 50, CS3006, CS3007, CS3008, Delta 60 and other model home speakers.

Apparently the crossover should be 2,000 Hz at 12 dB for these, but I've never seen a spec sheet or graph for these.

Info found online: EMIT stands for Electro Magnetic Induction Tweeter. They use very powerful Samarium Cobalt magnets covered by a thin diaphragm. It was a ribbon style tweeter that was very light, thin, and super fast. Although not indestructible, they had the most crystal clear high end ever reproduced by any speaker. Eventually these EMIT tweeters evolved into ribbon midranges and even upper bass drivers.

Was going to make home speakers with these but I have four EMIT-R tweeters and I really only need two.

Well that's what I've read, but I don't remember where. It is a large format tweeter with a magnet that could be used in a double homicide if the criminal wanted to be creative (don't get any ideas...). I've only put them in the dash of my old pickup to test them during some system design hemming and hawing and crossed at 2,500, 3,000, and 2,500 Hz at 24 dB for about 5 min each crossover at moderate volume. I don't know if that was safe but they sounded so damn good at the 2,500 mixing with a Hertz Mille 6.5" in the door. Only reason they didn't get installed is because they're so big and there was too much crap under where they'd fit on my dash to get them in there without surgery. They sounded really good firing up into the windshield. They will fit in my new truck but I'm wanting to do a 3-way so I don't need a second pair and, if push comes to shove and I want to do the EMIT setup in this truck, I still can.

Adding photos. The mark by the logo on one of them is from the tape I had holding bubble wrap around it. Honestly I was having a hard time rubbing it off because of the texture and wasn't in a position to do a good job of it, but it should come off. You can see a similar mark on the other one - I put a bit of tape in the same spot on each.






The model number is: 902-6759 (76224)

That's good to know. I was between 1/4 and 1/2 volume on a properly gain-tuned Kenwood Excelon amplifier (actually gains were just over half of what they could be before clipping would be present) when I was playing around with these as described above listening to Anna Ternheim and Amel Larrieux (my tuning go-to artists) - not harsh music.
