In my search for Altec 288, I encounter Altec 291-16A in great condition and I bough them, knowing that theses drivers are the same as the 288C minus the diaphragm (Symbiotik) and that these drivers in good condition are rare and pricey. You can found slignthy different spec sheet on the driver : earlier and later.
To my knowledge, no frequency response or other objective data was published on the net. Opinion are scarce and the few I found said it doesn't go as high as the 288C, but its midrange are smoother. Anyway I planned using either a JBL 2405 or EV T350 (or both) on top. Do you have any experience with this driver (horn coupling, amplifier used (in passive or active crossover configuration), crossover frequencies, blend with woofer and tweeter, etc.) ?

Thank GM. The 291-16A are not well known. It seem that it had little advantage over the 288, save power handling.

I purchased some altec 291 drivers about the same time as this post. I’ve been very pleased with them (mounted on a MRII594) I have found them to be smoother than my jbl 2446 (yuichi 290 or 2380a horns using ribbed or sl coated diaphragms).
Where the jbl benefited from an EV st-350 the 291s were pretty sonically similar with and without the EV (I think the EV dies around 15k) I did add a 2404 to help with the high end ultimately but could have easily been satisfied with just the 291 alone.
Anyway, just my 2 cents for anyone looking on information on these drivers.
