Does anyone know the box tuning specs of the 4645-K ? -K model, NOT -C model.

I just picked up a pair of 4645-K out of a movie theater, and am curious what the boxes are tuned to?

I found a lot of information on the site for the 4645-C, but nothing for my -K version.

The 4645-K have 2245H drivers in them, were these the drivers the boxes were designed for?

Thank you gentleman.

I'd guess ~30Hz, as that's what the 4645 with 2245 ran, IIRC.

Doing a little poking around here, it may have been that early 4645 examples were tuned for 25Hz,
then up to 30Hz (to keep the 2245 from blowing), then back down to 25Hz when the 2242 driver
was introduced.

... box dimensions, number of ports, dia and depth? That'd help pin it down.
