Clint Eastwood's HiFi

Xie -- No, I don't think so. There are several differences:

1)The EV has a horn near the top; the mystery speaker has a rectangular opening near the bottom.

2)The grillcloth is different, of course. Although grillcloths sometimes get changed over the years, the cloth on the EV appears to be original, as you can see by comparing to this catalog page.

3)Looking at the photo Shadorne linked to, it appears likely that the mystery speaker is rectangular as viewed from the top, while the EV is shaped for corner placement.

4)As Theo pointed out, the mystery speaker has something behind the grill near the upper right corner, while the EV does not.

They could be the Wharfedale W70 speakers with the Fruitwood cabinets.

Tannoy Lancaster or Devon

Those are close, Shadorne, but no cigar (I believe). They both have the wood surfaces meeting without the 45 degree bevel that CE's speaker had. Also the wood of his speaker appears to be thicker than on the Tannoy's. The Lancaster has the driver mounted closer to the top than on CE's speaker, and the bottom cutout on the Devon is different.

My guess is still that it was a Stephens, similar to the model shown in my 1960 Allied Radio catalog but bigger. Stephens was a California company which made some well regarded speakers, some of which (although I'd assume not this one) were physically designed by the famous furniture designer Charles Eames.

So as a celebrity living in California, he figures to have been aware of the Stephens brand and its reputation. Considering that, and the fact that the rest of the system looks like it could very well have been purchased at an Allied store (which sold Stephens), that theory seems to me to hang together pretty well.
