An Altec 515 woofer is more sensitive than the 416. IME the 515 (515B)will give you a little better midrange but less bass depth.

Note that the 825-828 VOT cabinet gives a stepped response with the horn loaded region above 125-150 hz several db higher in sensitivity than the region below which is vented. With a 416 woofer you may well be up around 105 db above 150hz.
