Identify JBL cabinet

[altec9440]

hello,

I can get empty JBL cabinets. But no stick or mark helping to identify model.

I would like to get original speakers specifications in order to find close replacement.

thanks.

Hmm, looks too 'modern' for my time, so can only recommend these folks and their discussion forums.

might be AC2212 or 15" version,

@GM : with a pseudo like alte9440B, I already tryed to register to audio heritage !!! But validation system did not worked, and administrator mail returned "permanent error"
@Greg32 : thanks, this AC2215 model seems very close to mine ; Back dimension is around 18cm, height 64cm, large 50cm.

If it's the correct model, it use JBL M115-8A speaker. I have some 421-8LF lying on the shelf but it will not do the job. With my poor knowledge on acoustics, I have only the feeling that AC2215 volume is far from 816A;

Any advice on working device ?

Thanks

I wondered of course as I use a 9444SA/A 😉, but I never cease to be amazed with some folk's laziness and there's lots more diverse folks browsing the forums, so I try to post to the public at large.

Hmm, first time I've heard of this, but will scope it out as time permits. In the meantime, a lot of them plus many others follow the James B Lansing Audio Society (Altec Lansing & JBL) on FB and maybe why the Heritage isn't as 'open' as it used to be.

The 421 8LF’s I have came in the Altec 1233 system which is a ported cabinet of similar size. True it needs EQing or a woofer compliment but it all depends on your goal.

Sealed ?? Altec 1233

Thanks GM, Bit of a brain fart there, I have corrected it to read ported.

the Heritage isn't as 'open' as it used to be.

may be only internet failure...

Not enough acoustic knowledge to make something coherent. I found a new altec restauration project 😉

The cab in the picture is from a JBL AC2215. Good quality well made cab but mediocre drivers for the price ($1500 ea. new) - M115-8A LF and the exceptionally nasty little 2412 HF driver. The 15" woofer isn't half bad for a cheap stamped frame driver, but that garbage 2412 is just unacceptable.
