Altec 423-4Z

Hi:

A friend has 2 of these 15"ers, they have a vented back plate and a white die cast frame, ceramic magnets, I cannot find any info here.

Does somebody know more about them?

Thanks.

all I can find on the 423 is that it is an OEM version of the 421A, bass musical instrument driver. There is a 423-8Z listed on JamminJersey,s website and this is what its listed as. 150w speaker! 8Z is 8 ohms and 4Z is 4 ohms.
