infinity tweeter replacement

4sfed5 · 27th May 2008, 11:52 AM

Hi everyone.

I have some Infinity reference 51's (circa 1996)and one of the silk dome tweeters has failed.
(part number 974206) 1" dome tweeter.

can anyone recommend a pair of replacements for these?
maybe some Vifas would be ok?

any help would be great if anyone has ANY info on these speakers or parts for them...

For spares, reference 51's do not seem to exist,

Glenn,

The part number you've given for your tweeter is not in keeping with Infinity's standard, which entails three digits followed by four. For instance, a 1" CMMD tweeter will have a part number of 974-7202. Is there a faded digit in there somewhere?

Nope, they still are. Infinity was its own company as founded by Arnie Nudell, Cary Christie and John Ulrich in Arnie's garage in 1968. They had a long run bring about a batch of commercially viable firsts (polypropylene cones, EMITs, servo-feedback woofers, first digital amplifier, first uber-reference [IRS]) and were bought out by Harman International, who also own JBL, ~1990 with Nudell's departure and Christie's following in 1995 (Ulrich was bought out by the other two ~1980).

the reference 51 seems to be an odd ball. iits a 3 way floor stander wih a 8"+5"+ tweeter...Ive googled it and come up with very little info.seems to be the little brother to the reference 61 which is the same except it adds another 8" to the package.

on the back it has "reference 51i" designed in america made in denmark.

the tweeter part number is correct and it has "made in France" on the tweeter sticker too.

What sort of impedance do infinity usually use for this age of speaker?

ANY INFO ON THIS VINTAGE (MID 90'S) INFINITY'S GREATLY APPRECIATED.
CHEERS

Hi,

Seem to be a version of the reference 50.
Pictures of the tweeter would help, Made in France = Audax usually.

Audax TW025A0 8 ohm tweeter, 1" textile dome
Now made by AAC of France

looks very similar and voicecoils are available...cheers
