Tweeter Identification (JBL and Other)

[gmilitano]

Hi, I found these tweeters in my closet. I was wondering if someone could help identify them. See picture.

I have 3 pairs of the silver ones and one pair of the dome tweeters.

I understand the silver one is a JBL tweeter. The markings are:
58P60DH-01HD
C5 Wave
Made In Japan

The dome tweeters are:
E69828
281TMB

If you look closely at the picture, you will see a dimple in the dome. They both have this dimple, so i assume it is part of the design.

I am particulary interested in specifications.

Cheers,
GM.

The JBL looks like it is from a Control 5. There are no published specs for this tweeter as far as I know. The other one actually looks alot like a Fostex. I'm not positive though.

No luck finding any info on the tweeter with a lens, but I did find the JBL tweeter on eBay:

http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&category=3276&item=5724521418

The tweeter was used in the JBL Control 5 monitor series of speakers and the following specs are noted:

1" Pure titanium dome magnet, 8oz. 8ohm voice coil, RMS/Peak 25w/50w, SPL 1W/1 - 96dB, 2KHz~22KHz frequency response. Tweeters have an outside diameter of 3.25" .


Do those numbers seem reasonable. The efficiency seems high.

That efficiency is very possible for the Control 5 tweeter. As for the rest, I've never tested one.

I have played around with them and looked at the crossover used in the Control 5. My best guess would be that the efficiency is about 88 - 90 dB. 96 is way too high.
