Small Format Drivers - Mounting Distance

[fred76]

Hello.

I want to get some info WRT the mounting distance of mounting bolts of small format Altecs.

Looking at published specsheets online, the modern 902 and 909 has a distance of 3" or 76.2mm radius between the holes/bolts (1.5" or 38.1mm from the center of exit)

The question is, if it has the same distance as the older types like the 802 or 806 series of drivers??? I haven't see drawings for these drivers.

I don't have actual drivers to measure so I thought it's best to ask here....

Thank you.

BTW here are the 902 and 909 drawings:

All two-bolt mount 800 and 900 series drivers have the same distance between the bolts. The proof of this is the 511B horn . . .

Hi whitebroncoii,

Thank you for the info. I wanted to make sure since I don't have the actual 800 series drivers present.
