to me a small book shelf is a 5 or 6 inch driver these are clearly and 8+
That's an 8". 6" bass drivers are for "mini" speakers... like my 760i.
The 762i is essentially the last version of Mission's original 700 speaker module, which had the bass driver on top, the HF is the middle, and the port on the bottom. I've got a pair of those, too (purchased new in 1982).
