Could be a bargain at a reasonable price .
Pretty sure that the 23746 moniker belongs to the ( rarified ) 806-8B as seen in this page from the 1975 catalogue .

May or may not be tangerine equipped, mine were not but do have very low mileage 23744 phragms in them. For an 806 the HF extension seems substantial, but those 32343 crossovers have some equalization in them and are more likely the reason for the more pleasing HF IMO.Quote:

I think RonSSS has some of these with the tangerines.
Appreciate the corrections guys.
Anyway, seems like 400 there , so may go at a good price...
I'm curious why someone so knowledgeable about the crossovers would not have popped the backs off the drivers to see what they were and do an ohm test. Seems suspiciously strange.
Ohm tests are way over rated IMHO. It's become fashionable to show a digital meter across a speaker when advertised.
They do show continuity I suppose.
Actually to check phase plugs a flashlight down the driver throat works.
I would like to see pics of the frams, agreed.
To ensure they're genuine, a serious value factor IMO.Quote:

Here's another pair on eBay.

John , your photo is quite interesting .
Clearly from all the great information presented in this thread so far, the usage of the 23746 ( oem stamp ) wasn't limited to only one back-cap style neither was it used exclusively with the two phase plug types ( which negates claims for it being either a 806-8A or 806-8B / my bad ! sorry ! ) .
Therefore , I need to ask; what was the actual determining factor ( commonality ) for inking that 23746 stamp onto a driver ?
- ( So far it looks like any 806-8x body type loaded with a 23744 diaphragm covered with any back-cap style, was all that was required )

I think that's a safe conclusion. The "logic" we derive from progressive changes to the loose drivers with model numbers doesn't seem to apply equally to part-numbered OEM drivers Altec installed in factory made systems. From the references, it appears the only common denominator was the intended use (system to be installed in).Quote:

To add to the confusion when looking at the drivers left today, many that Altec re-diaphramed (after the new-style rear caps were in use) came back with a new-style rear cap as part of the terminal conversion kit.
The last 3 entries below show the only 23746 uses prior to the creation of the '75 reference/ What came after may be lost to history.
(of interest to note in the '75 reference is that some OEM drivers listed their model-number counterpart, but others didn't. I believe there was a reason for that.)
